4 materials

4.1 This standard does not stipulate the material of the joint, but the materials used in all relevant components should be used with the aircraft drinking water, toilet water and platoon.

The water used in the water system is compatible with the chemicals. For stainless steel materials, the strength and hardness of the intended application should be guaranteed. Should pass the test

Verify that the material selected is suitable for the joint used to make the fluid used in the aircraft.

4.2 The surface and dimensions in Figures 1 and 1 shall meet the requirements of ISO 129-1, ISO 1101 and ISO 1302.
