Hello, We have a switch with a 0.010" thick cartridge brass contact arm that may be exposed to ammonia gas. We are concerned about the potential for SCC. Is there a 'safe' concentration of ammonia gas (ppm)? The switch environment is underground with moist air that may contain ammonia gas. The operating temperature range is 40F to 130F. Thank you.
