1. FOREWORD

Materials selection requirements for oxygen service have changed significantly since the last revision of this document. Historically, flammability and mechanical impact ratings were the main criteria for materials selection for oxygen service. Materials used in liquid oxygen (LO2) or gaseous oxygen (GO2) environments must be evaluated as described in NASA-STD-6001B, section 6.3. Materials selection for LO2 and GO2 environments in accordance with NASA-STD-

6001B begins with pre-selection of materials based on flammability and combustion test data, followed by flammability assessment of materials in the worst-case configuration and environment. Material flammability ratings based on NASA-STD-6001B test results for many materials, including those identified in this document, are found in the Materials and Processes

Technical Information System (MAPTIS) database and ASTM G63 and ASTM G94. If test results are not available through ASTM, NASA, or other sources, materials should be submitted to NASA/NE-L2-T for testing. Requests for flammability testing should be addressed to

NASA/MC: NE-L2-T, Kennedy Space Center, FL 32899. The test results will be electronically archived locally at KSC by NASA/NE-L and submitted for inclusion in MAPTIS II. If the materials are determined to be nonflammable in their use configuration and environment, and no additional material control is required, the materials may be used.

If the materials are determined to be flammable, an oxygen compatibility assessment

(OCA) must be performed on the components and systems in accordance with NASA/TM-2007-213740, which provides an overview of oxygen fire hazards and procedures which are consistent with the latest versions of ASTM G63, ASTM G94, and ASTM MNL 36. The OCA is used to determine whether the material may be used, or whether there is a need to perform supplemental material, configuration, or component testing. Requests for oxygen compatibility testing of materials should be addressed to NASA/MC: NE-L2-T, Kennedy Space Center, FL 32899. Oxygen compatibility test results will be transmitted to the customer by NASA/NE-L. The test results will be electronically archived locally at KSC by NASA/NE-L and submitted for inclusion in MAPTIS II.

Contact NASA M&P for further information on configuration or component testing.

Oxygen Compatibility Assessment (OCA) is the terminology used by NASA to describe the process formerly known as

Oxygen Hazard Analysis (OHA). The terminology was changed to avoid confusion between OHA and the non-oxygen-related Hazard Analysis performed by Safety. The OHA terminology is still used outside of NASA and is considered to be synonymous with OCA.

RELEASED - Printed documents may be obsolete; validate prior to use.

Materials used in oxygen systems for the Shuttle program were typically been tested for flammability and mechanical impact, which have been the basic criteria for materials selection for oxygen service for more than 20 years. Materials selection for post-Shuttle programs will be in accordance with the materials selection and OCA requirements called out in NASA-STD-6016 for flight and NASA-STD-5005C for GSE. Materials used in existing oxygen system designs with a history of safe use are considered acceptable for continued use; however, changes to materials used in such systems must be assessed on an individual basis. Contact NASA M&P for further information on materials with a history of safe use in oxygen systems and assessment criteria for new or untested materials.

When a material has been determined to be flammable by the NASA-STD-6001B Test 1, for nonmetals or Test 17 for metals, but has been determined suitable for use by an OCA, then a system/component safety rationale must be documented and must be approved by NASA M&P, either through a Material Usage Agreement (MUA) for existing drawings or NASA M&P signature on new or revised drawings. NASA Design Engineering and NASA M&P Engineering, through the signature of the cognizant organization, are responsible for ensuring that materials used in oxygen system designs have been assessed and determined acceptable for use. All new and modified oxygen system designs are required to be routed to NASA M&P Engineering for evaluation.

2. SCOPE

This document is intended as a resource for materials selection for design of oxygen systems for

KSC ground support equipment (GSE) and ground support systems (GSS). Flammability and combustion data extracted from NASA, ASTM, and industry documents for materials commonly used in KSC oxygen systems are summarized in Table 1 (Nonmetallic [Soft Good] Materials) and

Table 2 (Metals), in order to facilitate selection of materials for oxygen service. Autogenous

Ignition Temperature, Heat of Combustion, and Oxygen Index data are presented for nonmetallic materials; Promoted Ignition (NASA-STD-6001B, Test 17) data are presented for metallic materials. Codes are assigned to each material per KTI-5209, Material Usage Code.

The nonmetallic materials listed in Table 1 were also tested per NASA-STD-6001B supplemental tests for mechanical impact in ambient pressure LO2 (Test 13A) and variable pressure GO2 and

LO2 (Test 13B). The materials listed in Table 1 are rated A for mechanical impact up to the operating pressures listed in the table. Mechanical impact is only considered a credible ignition mechanism in certain components; mechanical impact test results can be utilized as an aid to the

OCA process when mechanical impact is identified as a credible ignition mechanism. Batch/lot testing for mechanical impact is no longer required for all soft goods used in oxygen service in the

1,650 - 6,700 psi range. NASA Design Engineering or NASA M&P may still require mechanical impact testing for operating pressures higher than the pressures at which the materials are rated A, in cases where mechanical impact is a credible ignition mechanism. In these cases the mechanical impact testing requirement will be stated on the drawing.

Meets the measurements/test condition requirements of NASA-STD-(I)-6001B Appendix A.5, Mechanical Impact for

Materials in Ambient Pressure LOX (Test 13A) and Mechanical Impact for Materials in Variable Pressure GOX and LOX (Test 13B), and does not require batch testing; number of tests = 20 and the number of reactions = 0 (zero), or number of tests = 60 and the number of reactions = 1 (one). Standard impact energy is 72 ft-lb, but may vary. Consult

MAPTIS for actual test conditions.

The vendors and applicable specifications for the materials listed in this KTI have been updated from the previous revision. These listings do not take into account the effects of unknown formulation and/or process changes that could be performed by a manufacturer, which could result in a material performing differently than these test results would indicate. Materials requiring initial testing, revalidation testing, or mechanical impact testing in accordance with NASA-STD-

6001B may be submitted to the KSC Materials Science Laboratory.

3. GUIDELINES FOR MATERIALS SELECTION FOR OXYGEN SYSTEM DESIGN

The list is new to this revision and is intended as a starting point for materials selection in the preliminary design phase. This list is to be utilized only as reference prior to evaluation of the system for oxygen service.

3.1 Nonmetallic Materials (Soft Good Materials and Lubricants)

Nearly all soft goods and lubricants are flammable in oxygen at ambient pressure. Selection of soft goods is based on their relative performance in various oxygen compatibility studies (autogenous ignition, heat of combustion, oxygen index, mechanical impact, and gaseous impact tests) and histories of use within NASA and other institutions. In addition to material compatibility, mechanical properties of soft goods and lubricants must be considered, e.g., cold flow of PTFE.

Information on material trade names within the chemical classes is found in Table 1. Consult

ASTM G63 for further information on selection of nonmetallic materials for oxygen service. The following nonmetallic materials are recommended for consideration for oxygen service:

Plastics

Polytetrafluoroethylene (PTFE)

Fluorinated ethylene propylene (FEP)

Perfluoroalkoxy (PFA)

Polychlorotrifluoroethylene (PCTFE)

Polyimide (PI)

Amorphous fluoropolymers

Elastomers

Fluorocarbonelastomer (FKM)

Perfluoroelastomer (FFKM)

Fluorosilicone elastomer (MVQ)

Lubricants

Perfluoropolyether (PFPE)

Chlorotrifluoroethylene (CTFE) oligomers

Molybdenum disulfide (MoS2) dry lubricants

3.2 Ceramics

All ceramics without organic fillers or binders may be used in oxygen service; however, due to the brittleness of many ceramics, consideration of the effects of failure, including the functionality of components within the system, is recommended. Contact NASA M&P for further information on use of ceramics in oxygen service.

3.3 Metals

Metals that burn in oxygen at 14.7 psia or less, or pose a toxicity hazard, are to be avoided in direct oxygen service. When selecting a metal for oxygen service, situational flammability must be considered. In general, metals, including those that normally exhibit high resistance to ignition, are more flammable in oxygen when they have thin cross-sections, such as thin-walled tubing, or when they are finely divided, such as in wire mesh or sintered filters. If a metal is found to be situationally flammable, special care should be taken to avoid ignition sources. Consult ASTM

G94 for further information on selection of metals for oxygen systems. The following metals are recommended for oxygen service:

Commercially Pure Nickel

Monel K-500 UNS

Monel 400

Inconel MA754

Commercially Pure Copper

Tin Bronze

Yellow Brass

Red Brass

Stainless steel is frequently used in high-pressure oxygen systems, even though it is flammable in certain configurations, such as meshes and thin sections. The use of stainless steels in high-pressure oxygen systems is possible, as long as the severity of the environment is controlled in order to minimize the probability of ignition and minimize the risk if ignition occurs. The following controls should be implemented when using stainless steels in high-pressure oxygen systems:

Systems are initially clean, to KSC-C-123 level 300A or better.

Proper system assembly practices are followed, in order to avoid contamination.

Inert gas blow-downs are performed, in order to reduce contamination.

System designs eliminate the use of tubing with a 90-degree bend radius wherever possible.

Valves are designed to reduce generation of contaminates, e.g. non-rotating stems.

Valve soft goods are surrounded by metal with low Heat of Combustion, such as Monel.

Remote or limited operations are employed, in order to minimize personnel exposure.

Gas velocities in lines are low (< 100 ft/s).

Kindling chain is taken into consideration.
