CGA G-4.10

This publication addresses high pressure oxygen breathing gas systems with pressures higher than 435 psig (3000 kPa) and with an oxygen content above 23.5% by volume. It applies in particular to nonmetallic materials which if they ignite or decompose could contaminate the gas stream with toxic products. The recommendations of this document can be beneficially applied at pressures lower than 435 psig (3000 kPa).

NOTE--Ceramics and glass are excluded from the scope of this document.
