MIL-STD-1330-SUP-2 Precision Cleaning and Testing of Shipboard Oxygen, Helium, Helium-Oxygen, Nitrogen, and Hydrogen SystemsThis standard provides the requirements for precision cleaning and testing of oxygen or oxygen-enriched systems and components; oxygen generating plants including nitrogen, hydrogen, and demineralized water support systems and components; and helium, helium-oxygen, and hydrogen life support systems and components. Each activity will implement the applicable requirements of this document through a locally prepared and approved procedure. Activities subject to additional quality assurance requirements such as NAVSEA SS800-AG-MAN-010/P-9290 or NAVSEA SS521-AA-MAN-010 will obtain procedure approval from the applicable certifying activity.

A.3 PROCEDURE

A.3.1 Compatibility testing. Compatibility is determined by evaluating material properties such as weight, volume, tensile strength, elongation, or hardness and, for metals, inspecting the surface for discoloration and degradation after exposure to the fluid of interest. Guidelines for performing material compatibility testing are as specified in A.3.2 through A.3.4. These guidelines are conservative. Accordingly, local engineering review of compatibility testing performed or actual experience may result in different conclusions. Results of compatibility testing using these guidelines are provided in tables XIII through XV. If experience or testing indicates that a material is less compatible than as indicated in these tables, contact NAVSEA. If a material of interest is not

listed in these tables, compatibility testing shall be accomplished using the following guidelines.

A.3.2 Metal. ASTM D 930 or ASTM D 1280 provide guidance for performing compatibility testing on metals. The allowable corrosion limits are as specified in MIL-DTL-24800.

A.3.3 Rubber. ASTM D 471 or ASTM D 1414 provide guidance for performing compatibility testing on rubbers. The criteria to determine the exposure limits are as specified in table XVI.

A.3.4 Plastic. ASTM D 543 provides guidance for performing compatibility testing on plastics. The criteria to determine the exposure limits are as specified in table XVII.
