Materials that contaminate oxygen or are adversely affected by continuous service with oxygen shall not be used. The following test methods shall be used to verify compliance with material requirements established in a design specification.’

Paragraph 3.1.1

a. Resistance to Flammability

To be revised: ‘Except for small parts like knobs, triggers, fasteners, seals, and electrical parts that don’t contribute significantly to fire propagation, materials including packaging shall comply with CS 25.853(a) and Appendix F, Part I(a)(1)(iv)’

The cleaning method shall be either manufacturer recommended, or according to SAE ARP1176, Oxygen System Component Cleaning and Packaging. Cleaning and sterilising procedures shall be included in the Component Maintenance Manual (CMM).’

Paragraph 3.1.4

To be revised: ‘Elastomeric Components: A tag or leaflet describing service life limits of elastomeric components and a suggested method to inspect for deterioration in these components shall be attached to the mask. If not attached, the tag shall be included with the packaged mask as delivered to the user. Silicone rubber parts, having unlimited shelf life, are exempt from this requirement.
