Content
This specification covers the test procedure for producingenvironmentally related corrosive atmospheres to determine thereaction of plated or unplated surfaces when exposed to differentconcentrations of flowing gas mixtures1&2.
Description
Samples that are to be evaluated may be mated or unmatedconnectors, components, or experimental materials. They are placedin an environmentally controlled chamber that is monitored by algasanalyzing system for controlled concentrations of the gas mixture.Corrosion rates are monitored by copper and, unless otherwisespecified, silver, control coupons placed in the chamber for eachtest. These control coupons are removed and analyzed usingcoulometric reduction for factors related to amount and type ofcorrosive product growth to confirm corrosivity control level.Methods are based upon those developed by W.H.Abbott, BattellColumbus Laboratories, for the Environmental Studies Group.
Safety
This procedure involves the use of hazardous materials,operations, and equipment. This specification does not purport toaddress all of the safety problems associated with its use. It isthe responsibility of whoever used this specification to consultand establish appropriate safety and health practices and determinethe applicability of regulatory limitations prior to use.
