Foreword

This Standard provides a framework and supporting processes for determining elements of an audiovisual system that need to be verified, the timing of that verification within the project delivery cycle, a process for determining verification metrics, and reporting procedures.

As audiovisual systems have increased in complexity, the chances of misconfiguration, improper installation, and failure to conform to project requirements increase. Managing expectations and verifying conformance with stated project requirements of audiovisual (AV) systems is the major goal of this Standard. While many organizations have internal processes and verification procedures, there is an industry-wide need to utilize project documentation along with this Standard to identify elements within an AV system that require measurement and verification. Use of this Standard supports a comprehensive, systematic, and practical approach to verifying performance of AV systems.

This Standard requires that project documentation has been created for the project being verified.

Documentation will vary from project to project and the standard does not prescribe the nature and extent of the project documentation. Conformance to the Standard is not possible without project documentation.

This Standard assumes that a project owner’s operational specifications have been established in the system/project documentation.

This Standard does not provide a “one size fits all” verification pathway, but a means to enable the user of the Standard to develop a project-specific list of system performance verification items based on performance requirements defined in the project’s documentation. Being able to assess the performance of the audiovisual system based on what was defined in the project’s documentation should reduce dissatisfaction at the end of the project.

Using the Standard, consultants, integrators, manufacturers, technology support staff, owners, third-party commissioning agents, and architects who have system performance verification processes in place can integrate those existing processes into the framework this Standard provides, adding customized items to those already defined in the Standard.

Benefits of using this Standard are not limited to but include:

Ability to streamline verification tests and reporting;

Providing a verifiable outcome;

Creating a common language between all parties;

Aligning outcome and performance expectations at an early stage in the project;

Creating reporting that completes the project documentation; and Reducing project risk through early identification of problems, thereby reducing the likelihood of remedial work.

This Standard should be used in conjunction with ANSI/INFOCOMM 2M-2010 Standard Guide for Audiovisual Systems Design and Coordination Processes as well as other relevant performance standards.

About ANSI

The American National Standards Institute, Inc. (ANSI) is the national coordinator of voluntary standards development and the clearinghouse in the United States for information on national and international standards. An American National Standard implies a consensus of those substantially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered and that a concerted effort be made toward their resolution. The use of an American National Standard is completely voluntary. Its existence does not in any respect preclude anyone, whether he or she has approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard.

InfoComm International Standards Development

InfoComm International maintains a Standards Steering Committee that provides oversight to the standards development task groups responsible for specific standards. The Steering Committee reports to the InfoComm International Board of Directors, whose approval is required before standards may be submitted to ANSI.

1 Scope, Purpose, and Application

1.1 Scope

1.1.1 This Standard provides a comprehensive evaluation framework and associated processes to verify functionality and performance of an audiovisual system in accordance with the system’s project documentation. The Standard identifies the timing of verification; a list of reference items to be considered, delineated by their function as related to the system; a process for determining verification metrics; and reporting procedures.

1.1.2 This Standard identifies audiovisual system performance-evaluation requirements for the following 13 functional categories:

Audio Performance Video Performance Audio/Video Performance Cable Management, Termination, and Labeling Control Performance Electrical Information Technology Operations and Support Physical Environment Physical Installation Serviceability Wireless System and Record Documentation

1.2 Purpose

1.2.1 The purpose of this Standard is to provide a framework for the verification and reporting of the performance of an audiovisual system based on the requirements specified in the system’s project documentation. The Standard defines 160 potential verification items; a process for determining which items are germane to the project and a way to incorporate additional items; a process for defining the evaluation metrics for verification; a process for verifying the items; and a process for how and when to report those results.

1.3 Application

1.3.1 This Standard can be utilized by all parties involved in the audiovisual system installation process including consultants, integrators, manufacturers, technology support staff, owners, third-party commissioning agents, and architects to verify the performance of audiovisual systems throughout the integration process.

1.3.2 Planning for the use of this Standard should begin with the project’s initiation. The framework provided by this Standard should be integrated into the project’s project management and/or quality management processes. For organizations that have existing project management and/or quality management programs, the framework provided by this Standard can be integrated into existing processes. Conformance to the Standard shall require that all requirements of the Standard are included; this Standard does not provide for partial conformance.

© 2013 by InfoComm International® Page 8

1.3.3 This Standard is aligned with ISO 21500:2012:Guidance on project management, where the activities of this Standard take place within the Implementing, Controlling, and Closing process groups. The Standard is aligned with ANSI/INFOCOMM 2M-2010, Standard Guide for Audiovisual Design and Coordination Processes, where the activities of the Standard take place within the construction phase. For projects where it is known that this Standard is being implemented at project initiation, it is recommended that users of this Standard begin planning for conformance to the Standard at that time.

Figure 1 – Illustration of Implementation Phases

1.3.4 This Standard can be applied to any size (scope and/or value) audiovisual system as long as its project documentation clearly cites (and completes) a project-specific verification list during initiation and then subsequently documents verification through the project phases.

1.4 Exceptions

1.4.1 Specific measurement metrics

This Standard does not provide measurement metrics for any defined reference verification items in Section 9. Metrics (beyond pass/fail) should be determined by following the process in section 6.2 of this Standard.

1.4.2 Measurement methodology

This Standard does not prescribe any specific methodology for achieving the required metrics. Comparable measurement techniques and methods exist in many cases, and the user of this Standard shall choose a method by using the metrics selection process hierarchy as defined in Section 7 of this Standard once a project-specific reference verification item is identified.

1.4.3 This Standard does not include prescription for corrective action.

1.4.4 In addition, this document is not designed as a technical training manual or roadmap for specific actions. It is expected that all parties using this Standard have or will obtain the necessary training and experience through other means.

4 Verification Framework

4.1 Overview

4.1.1 This Standard provides a customizable methodology that yields project-specific performance verification reporting for an audiovisual system. While there is an overarching methodology for the framework, there is no “one size fits all” approach when it comes to system performance verification. This framework is intended to be used with existing project and quality management processes implemented by the organization. Additionally, existing organizational verification processes can be adapted to be in conformance with the Standard.

Figure 2 – Framework Process Groups

4.2 Implementation

4.2.1 Implementation of the Standard requires that project documentation shall exist. If project documentation does not exist, then it shall be created prior to the application of this framework.

4.2.2 ANSI/INFOCOMM 2M-2010, Standard Guide for Audiovisual System Design and Coordination Processes, provides descriptions for audiovisual system project documentation and can be used as a guideline for creating project-specific documentation.

4.2.3 This Standard and ANSI/INFOCOMM 2M-2010 are complementary and not mutually exclusive.

4.2.4 Users of this Standard shall create a project-specific verification report at verification phases utilizing the processes outlined in this Standard. Workflow for the application of the Standard can be subdivided into four sequential process groups:

4.2.4.1 Verification Item Selection Process Group

The first group defines the process for selection of verification items that are germane to the system. Selection is based on the performance requirements as defined in the project documentation. All reference verification items included in the reference verification list in this Standard may not be applicable to project-specific performance requirements.

Additionally, the Standard provides for the ability to include project-specific verification items not defined in this Standard but defined by performance requirements in the project documentation.

4.2.4.2 Verification Metrics Selection Process Group

The second group defines the process for selection of project-specific verification metrics for each item selected as defined in 4.2.4.1. The specific verification metric shall be based on the stated requirements in the project documentation and determined using relevant sources identified by the process outlined in this section.

4.2.4.3 Performance Verification Process Group

The third group defines the process for completing the performance verification for the project. Performance verification shall occur multiple times throughout the project. During this process, testing of performance and conformance with metrics as defined in 4.2.4.2 will occur.

4.2.4.4 Verification Reporting Process Group

The fourth group defines the process for issuance of a verification report based on the outcome of the system’s performance. Reports shall be issued multiple times during the project to provide the most up to date verification information as the project progresses. The verifier shall be required to acknowledge conformance to the Standard with each report issued.

5 Verification Item Selection Process Group

5.1 Overview

This process, as noted in 4.2.4.1, defines the means that will be utilized to determine which reference verification items will be included within the project-specific verification.

The items selected serve as the basis for establishing metrics (4.2.4.2) and verifying the system’s performance.

5.2 Implementation

5.2.1 The system verifier shall be responsible for conducting this process in consultation with all applicable stakeholders for the project.

5.2.2 Verification items shall be selected based on the information and requirements defined in the project documentation.

5.2.3 In all cases, items mandated by regulatory requirements shall be included.

5.2.4 The Standard provides a reference list of 160 potential verification items. Verification items are organized by both functional categories and verification phases. The functional categories group verification items by system function. The verification phases identify at what point in a project verification should take place. Certain items identified as reference verification items require verification during multiple verification phases.

5.2.5 The reference verification items provided shall not be regarded as an exhaustive list when a project’s documentation outlines the need for additional specific requirements or an organization’s processes require additional items. Provisions are made to include these additional verification items in the project-specific verification process and reporting.

5.2.6 To determine which verification items are required:

1) Review regulatory requirements relating to the audiovisual system (e.g., requirements for the system to respond to an emergency condition), identify applicable reference verification list items, and include these items on the project-specific verification item list.

2) Review project documentation to determine specific performance requirements, identify applicable reference verification list items, and include these items on the project-specific verification item list.

3) Review manufacturer-provided information for equipment on the project, identify applicable reference verification list items, and include these items on the project-specific verification item list.

4) Review remaining reference verification list items, identify all additional applicable verification list items which were not included in the project documentation but are necessary to ensure the system performs as specified and include these items on the project-specific verification item list.

5) Identify any specific client-/owner-required tests not already covered and include these items on the project-specific verification item list.

5.2.7 The above process shall be applied for each system on the project.

5.2.8 A separate verification list shall be completed for each system.

5.2.9 All reference verification items in the Standard shall be included in verification reports.

Items identified as not applicable (N/A) shall be listed either in sequence or as a list at the end of the verification report.

5.3 Reference Verification Items

5.3.1 Overview

This Standard defines 160 reference verification items that exist within 13 functional categories, four verification phases, and two milestones. Although each reference

© 2013 by InfoComm International® Page 14 verification item exists within only one functional category, some items are included in multiple verification phases. A comprehensive reference verification list has been provided;

however, specific projects may include systems, technology, or functional requirements that require additional verification items. Users of the Standard may add customized verification items to the items identified during the Verification Item Selection Process (see 4.2.4.1) and include additional tests that exceed items required in each functional category. A complete list of reference verification items identified by functional category and verification phase is found in Section 11.

5.3.2 Implementation

5.3.2.1 For consistency, users of this Standard shall maintain the exact numbering scheme for verification items as defined in this Standard.

5.3.2.2 For applications that require project-specific verification items, those items shall be numbered as PROJ-XXX where XXX is the incremental number of each additional project-specific item, numerically starting with 100 (i.e., PROJ-100).

5.5 Verification Phases and Milestones

Figure 4 – Verification Phases and Milestones

The verification phases and milestones are defined as follows:

5.5.1 Pre-Integration

Verification items that take place prior to systems integration. These items will generally verify existing conditions or coordinated trades activities required for AV system installation (e.g., device enclosures, backing/blocking/framing).

5.5.2 Systems Integration

Verification items that take place while the audiovisual system(s) is/are being integrated or built, including off-site and on-site work. These items will generally verify proper operation or configuration so that the system can function (e.g., equipment mounted level and plumb, phantom power, termination stress, AV rack thermal gradient performance).

5.5.3 Post-Integration

Verification items that take place after the audiovisual system(s) has been completed.

These items will generally verify system performance against verification metrics as defined in the project documentation (e.g., projected image contrast ratio, audio and video recording, control system automated functions).

5.5.3.1 Substantial/Practical Completion

Verification milestone that indicates conditional acceptance of the project has been issued by the owner or owner's representative, acknowledging that the project or a designated portion is substantially/practically complete and ready for use by the owner, however some requirements and/or deliverables defined in the project documentation may not be complete. This milestone occurs at the end of the post-integration verification phase.

5.5.4 Closeout

Verification items involved with closing out the project. These items will generally be related to documenting the As-Built/As-Is status of the system(s) and transfer of system software, among other (e.g., control system test reporting, As-Built drawings complete, warranties) items.

5.5.4.1 Final Acceptance

Verification milestone that acceptance of the project has been issued by the owner or owner's representative, acknowledging that the project is 100% complete and all required deliverables, services, verification lists, testing, verification, and signoffs have been received, and all requirements defined in the project documentation have been satisfied and completed that occur at the completion of the closeout verification phase. No further project activity will take place after this milestone is verified.

© 2013 by InfoComm International® Page 17

5.6 Verification Phases Implementation

5.6.1 Certain verification items may need verification at multiple times during a project.

5.6.2 The reference verification items provided in this Standard define the verification phases at which those items should be tested. Where additional items are added on a project-specific basis, these shall also be allocated a verification phase.

6 Verification Metric Selection Process Group

6.1 Overview

6.1.1 Once the verification items have been identified, each item shall require a pass/fail verification.

6.1.2 There are 16 (out of 160) specific verification items identified in this Standard that require a measurement in addition to pass/fail to validate performance. These verification items are identified in Section 9 item descriptions. The item descriptions include a sentence that reads, “This verification item shall require a metric to be verified.”

6.1.3 There are 11 (out of 160) specific verification items identified in this Standard that it is recommended include a measurement in addition to pass/fail to validate performance.

These verification items are identified in Section 9 in the reference verification list item descriptions. The item descriptions include a sentence that reads, “This verification item should require a metric to be verified.”

6.1.4 This Standard does not identify the method or measure beyond pass/fail; this should be identified and defined by the user of the Standard.

6.2 Selection Process Implementation

6.2.1 Each project-specific verification item that has been identified and requires a metric in addition to pass/fail shall follow this selection process:

1) Review client/owner’s key priorities – in terms of cost, quality, time, functionality, and performance.

2) Start with the best-case metrics for the given type of installation (e.g., general meeting room, boardroom, video conferencing, stadium).

3) Review metrics with owner, building designers and/or equipment manufacturers to confirm that best-case metrics are achievable.

4) Modify metrics to suit project and define target metrics for the project.

6.2.4 In many instances, best-case metrics may not be achievable as part of a system installation due to the existing or planned building environment. When conflict exists between the building environment and best-case metrics for the audiovisual system, a discussion should take place between the system verifier and the owner to determine an agreeable metric.

8.1 Overview

8.1.1 The system verifier shall provide reporting to the client/owner and/or the contractually identified stakeholder(s) throughout all verification phases of the project. At a minimum, the system verifier shall issue reports at the end of the pre-integration, integration, post integration, and closeout verification phases.

8.1.2 If project reports are issued only once per verification phase, the reports shall include the results of all project-specific verification items for that verification phase in a completed and documented manner to be considered in conformance with this Standard.

8.1.3 Reports may be issued multiple times per verification phase based on project requirements. When considered together, the reports shall include results of all project-specific verification items for that verification phase in a completed and documented manner to be considered in conformance with this Standard.

8.1.4 If an event (e.g., change order, remediation work, audiovisual system design changes, building design changes, program scope change) causes a project-specific verification item to be verified additional times, the system verifier shall reissue the verification report for all project-specific verification items that have been verified again.

8.1.5 At the conclusion of the project, the system verifier shall issue a verification report for the final acceptance milestone. This report shall be cumulative and contain all required report elements and the results of all project-specific verification items that have been verified in all verification phases of the project. After the final acceptance report has been issued, no further reports shall be issued. This report shall be organized by the sequential verification phases.

8.2 Reporting Format and Implementation

8.2.1 The format of the report shall be either printed, electronic, or both. Electronically formatted reports shall be issued in a format that prevents subsequent editing.

8.2.2 Each issuance of the verification report shall include the following:

8.2.2.1 Report Header

1) Project name

2) Name of system verifier

3) Date of issuance of report

4) Verification phase covered by report

5) To whom the report is being issued

8.2.2.2 Project-specific verification items from the verification phase covered by the report

1) Verification item number

2) Verification item name

3) Verification item-defined metric (e.g., visual inspection, measure image contrast ratio of 7:1, SPL at least-favored listener measured at 80 dBSPL)

4) Verification item measurement result (if required – see section 6.1)

5) Verification item pass/fail result

6) Name of the verifier/party completing item

7) Date of the verification

8) Notes and comments (if necessary)

8.2.3 The reports shall organize the verification items in the same categorical order as they are presented in the Standard. Verification items shall be ordered according to the following hierarchy:

1) Functional category

2) Item number

8.2.4 Optional elements may be included in the reporting that are required for the project. Items such as report version numbers, traceability, item descriptions, recommendations for remedial actions, and change logs may be included at the discretion of the system verifier or as required by project documentation.

8.2.5 In the event that the project is suspended or delayed indefinitely, a report shall be issued noting that the process cannot be continued, and all relevant and supporting files that are used to track, monitor, and/or note the verification process and status shall be transferred to the owner for future use.
