source and/or CCRL.
Follow all AAP Procedures for completion of corrective actions by the specified deadlines.
Laboratory Assessment Program
The AASHTO re: source Laboratory Assessment Program (LAP) provides on-site assessments of laboratories that perform testing of materials used for construction and the preservation of roads, bridges, and vertical infrastructure. Participating laboratories include state DOT’s and other government laboratories, universities, research facilities, material producers, and commercial testing laboratories.
AASHTO re:source’s rigorous on-site assessments are a critical step in obtaining and maintaining accreditation through AASHTO.
Benefits
By receiving an AASHTO re: source on-site assessment, your laboratory is able to demonstrate conformance to specific national and international standards experience a thorough examination of technician competency get expert advice and first-hand feedback on laboratory best practices seek AASHTO accreditation
Scope of On-Site Assessments
During on-site assessments, our expertly trained assessors observe a demonstration of each standard test method or practice by the laboratory’s technical staff, and the apparatus associated with each test is evaluated. We currently offer assessments for AASHTO, ASTM, and ISSA standards, as well as some state methods. A full list of standards offered by LAP may be found on the Tests and Fees page (see AASHTO re:Source website). The assessment may also include a thorough review of the laboratory’s quality management system for conformance to AASHTO R 18 and other quality system standards (D3470, D3666, C1077, E329), including internal policies and procedures, records of technician training and competency evaluations, equipment calibration, standardization and check records, as well as internal audits.
For laboratories that require an assessment in concrete, cement, or pozzolan, slag cement, or mortar, these on-site assessments are conducted by the Cement and Concrete Reference Laboratory (CCRL).
Laboratories who obtain an assessment through CCRL are also eligible for participation in the AASHTO Accreditation.
On-Site Assessment Process
Laboratories must submit an Assessment Request in order for our staff to schedule an on-site assessment at your facility. You will be notified of the specific on-site assessment date approximately 4- 6 weeks in advance. View the estimated schedule to determine when we will be visiting your area as part of our normal tour schedule. If you would like to have an assessment at a time other than that shown on the schedule, additional travel costs for an out-of-sequence assessment may apply. Regular assessment fees are calculated based on the requested scope of testing.
Before the Assessment
For Laboratories Seeking Accreditation Only
Once your assessment has been scheduled, you may be asked to submit pre-assessment documentation through our online system. You may be asked to provide:
Personnel qualifications and certifications held by your technicians
A list of field and laboratory technicians at your facility An organizational chart A copy of your laboratory’s quality system policies and procedures that demonstrate conformance to AASHTO R 18 (new laboratories only).
For All Laboratories
Your assessor will be in contact with you 2-4 weeks before the scheduled start date of your on-site assessment. The assessor will be able to answer any technical or logistical questions that you have about the assessment process. The assessor will also send you an official agenda for the assessment that will provide you with additional information on what to expect while the assessor is visiting your facility.
Laboratories should be familiar with the specific requirements for each requested test or procedure. Current versions of each applicable test method should be available at the testing laboratory for review by the Assessor.
Review Assessment Preparation Lists that are available on our website. These lists describe the steps that laboratories should take to prepare for each test, such as sample preparation and testing guidance.
During the On-Site Assessment
A typical assessment begins with an opening meeting, where the assessor reviews the scope and schedule of the assessment with laboratory personnel.
The laboratory’s technical personnel demonstrate each test method while being closely observed by the Assessor. The testing is performed on samples of construction materials that are provided by the laboratory.
The apparatus associated with each test method is also examined for conformance to AASHTO and/or ASTM requirements. Our assessors are equipped with specialized equipment for this purpose, such as standard masses, and digital calipers, and thermometers.
If the laboratory is seeking or wishes to maintain accreditation through AASHTO, a thorough review of the laboratory’s quality management system for conformance to AASHTO R 18 will occur. Our assessors will conduct interviews with key personnel, review equipment records, training and competency evaluation records, test reports, internal audits, and other critical documents as part of this process.
At the conclusion of the assessment, the Assessor will conduct a closing meeting with laboratory staff. A preliminary report of the findings uncovered during the assessment is provided. The findings are discussed and questions are answered by the assessor to ensure that each finding is thoroughly understood by laboratory staff.
After the Assessment
Upon return to the AASHTO re: source office, the official final report is issued and then distributed to the testing laboratory within 30 days of the closing meeting.
If participating in the AASHTO Accreditation Program, laboratories are required to resolve nonconformities noted in the on-site assessment within 90 days of the issuance of the report.
CCRL Laboratory Inspection Program
Laboratory Inspection Process
The program provides a laboratory with a comprehensive account of how its procedures, practices, equipment and facilities compare with ASTM standards requirements. The CCRL laboratory inspector checks critical equipment dimensions and operating characteristics; watches a technician demonstrate test procedures; and reviews the quality system when covered by appropriate ASTM standards. The goal is to provide a consistent and fair evaluation so that the laboratory and its clients may have confidence that testing is of high quality and that ASTM standards are being used correctly.
The sponsors have stipulated that CCRL shall not act as a referee in disputes concerning the quality of materials, the suitability of testing apparatus, or the ability of a laboratory to perform testing work in a satisfactory manner. Because of these prohibitions, all of the services rendered are advisory in nature and laboratories are not rated, certified or accredited by CCRL. However, because of the reputation of CCRL the programs are often used by others in providing accreditation.
CCRL Proficiency Sample Program (PSP)
Proficiency Sample Program Overview
CCRL Proficiency Sample Programs also support accreditation programs conducted by others.
Participation in proficiency sample programs also permits laboratories to check consistency of their testing. Results from such programs can be used to evaluate quality of testing between laboratories, and to help identify problems with equipment or procedures. Laboratories are required by ASTM C1222 and C1077 to participate in a proficiency sample program. The Proficiency Sample Programs were developed as a means for a laboratory to monitor the quality of its testing between CCRL on-site assessments. The programs are overseen by ASTM Committees C-1 on Cement and C-9 on Concrete and Concrete Aggregates. Responsibility for the assignment of fees is assumed by the committees, and their payment is made to ASTM. The Proficiency Sample Programs are based on the two-sample system described in papers by Youden [1], and by Crandall and Blaine [2] in the 1959 Proceedings of the American Society for Testing and Materials.
All programs are conducted in a similar manner. At intervals of either 6 or 12 months, quantities of two slightly different lots of a material (cements, pozzolans, concrete aggregates, masonry sand, and masonry units) are procured from commercial sources. This material is then homogenized using well defined procedures and divided into individual test samples at the National Institute of Standards and Technology (NIST). Special instructions, and all necessary reporting forms, are furnished with each set of samples. The test procedures to be performed are taken from current ASTM specifications. The specified tests are performed and the results reported to the CCRL for review and evaluation. Test results reported by an individual laboratory are treated confidentially as to source. Approximately six weeks after the samples are distributed, all participants receive a preliminary report which shows tentative average values and standard deviations for each determination, based on a limited number of returned results.
Within two months, a detailed final report is distributed. This report contains average values, standard deviations based on all applicable data, and scatter diagrams. In addition, precision values and other statistical information are produced for use by ASTM committees and other interested organizations.
Scatter diagrams are prepared for each test performed by the laboratories. For each pair of samples, the test results of the odd-numbered sample are plotted on the X (horizontal) axis, and the results of the even-numbered sample are plotted on the Y (vertical) axis. A substantial variation of its test values from the center of the diagram is generally of concern to a laboratory. A continuing trend of large variations indicates a need for some corrective action, either in apparatus or technique. To focus attention on significant deviations from the average, each laboratory is given a rating on each determination using a rating scale based on the standard deviation. The ratings have no significance beyond indicating the difference between the individual laboratory result and the average for a particular test. To help give meaning to the ratings obtained by an individual laboratory over a given period of time, performance charts were developed. These charts, which are distributed annually to laboratories, visually show a participant's deviation from the average value on the ten most recent sample pairs, thereby providing a means of monitoring the general tendencies and bias of a laboratory's test results. This information gives some indication of a laboratory's overall proficiency for given tests.
