4.0 REQUIREMENTS

4.1 MATERIAL RATING

Section 6.0 lists those materials that have been determined to be compatible with LOX and/or GOX using NASA-STD-6001 criteria. Ratings indicate the following:

4.1.1 "A" Rating

Materials rated "A" for LOX are exempt from batch testing when used in LOX systems at pressures not exceeding that shown and temperatures not exceeding -275°F (-171°C). Materials rated "A" for GOX are exempt from batch testing when used in GOX systems at pressures not exceeding that shown and temperatures not exceeding 160°F (71°C) unless specified otherwise in section

6.0. Batch testing is required for any "A" rated material when used at a pressure higher than shown in section 6.0 or temperatures exceeding 160°F (71°C) for GOX, unless specified otherwise in section 6.0, or -275°F (-171°C) for LOX.

Materials listed by trade name. When an "A" rated material is identified by trade name (e.g., Halocarbon grease) the listed trade name material is exempt from the requirements for batch testing for pressures not exceeding that shown. If a specific material is listed (e.g., Halocarbon 25-5S grease) only that specific material is exempt. Unlisted trade name materials with the same composition as listed trade name materials must be qualified by batch testing unless purchased to a listed specification.

Surface Cleanliness Standard of Fluid Systems for Rocket Engine

Test Facilities

1. SCOPE

1.1. Purpose

The purpose of this standard (STD) is to specify the cleanliness levels and the minimum contamination control requirements (processing, handling, protection, and test/inspection) for surfaces that come in contact with any fluid medium. These requirements pertain to the “critical surfaces” of parts, items, components, equipment, assemblies, subsystems, and systems used for

NASA’s rocket propulsion test program.

1.2 Applicability

a. This standard is applicable to ground-based rocket propulsion test facilities for propellant, pressurant, pneumatic, and hydraulic systems that require cleanliness certification.

Specifically, these are the test stands and facilities under the purview of the NASA

Rocket Propulsion Test (RPT) Program.

b. All system and product cleanliness levels shall meet or exceed program or test article requirements. Program- or customer-specified requirements may impose additional cleanliness or process requirements. In such situations, process changes and supplemental procedures may be required to satisfy any additional program- or customer-specified requests.

c. This standard may be cited in contract, program, and other Agency documents as a technical requirement.

d. Mandatory requirements are indicated by the word “shall.”

e. Tailoring of this standard for application to a specific program or project shall be approved by the Technical Authority for that program or project.

1.3 Responsibilities

1.3.1 General

a. NASA and contractor personnel responsible for engineering design, manufacture/fabrication, propulsion test operations, cleaning and inspection, calibration, and analysis activities shall implement this STD.

b. NASA and the Contractor shall ensure compliance with requirements of this STD through surveillance, auditing, and process verification.

c. Design specifications and drawings shall identify cleanliness levels by the alphanumeric or numeric designations defined in this STD.

d. The user is responsible for assuring suitability of the cleaned item for its intended use.

1.3.2 Quality Assurance

The performing organization’s QA (quality assurance) shall review and verify that the surface cleanliness requirements for fluid systems are satisfied.

1.3.3 Safety and Environmental

a. All users of this standard must review pertinent Material Safety Data Sheet (MSDS) material specifications and work instructions to assure safety of personnel and protection of the environment and facilities in fulfilling the requirements of this STD.

b. All materials and processes required to fulfill the requirements of this STD are subject to applicable Federal, State, and local environment, health, and safety regulations, standards, codes, and operating procedures (e.g., work instructions). The performing organization is responsible for determining and establishing the appropriate environmental, health, and safety practices that are in compliance with all applicable regulations.

c. Questions regarding these activities, including air emissions, spills, solid and hazardous waste inventory, storage, removal, disposal, discharges, and waste minimization (e.g., recycling) shall be referred to the cognizant personnel within the performing organization.

1.3.4 Training

a. The performing organization or contractor shall assure that all personnel responsible for contamination control functions are trained as required to assure proficiency within their assigned tasks.

b. The processing organization or contractor shall establish personnel certification with traceable documentation.

2. APPLICABLE DOCUMENTS

2.1 General

a. The documents listed in this section contain provisions that constitute requirements of this standard as cited in the text of Section 4.
