This part of IEC 60749 describes a salt atmosphere test that determines the resistance of semiconductor devices to corrosion. It is an accelerated test that simulates the effects of severe sea-coast atmosphere on all exposed surfaces. It is only applicable to those devices specified for a marine environment. The salt atmosphere test is considered destructive In general, this salt atmosphere test is in conformity with IEC 60068-2-11 but, due to specific requirements of semiconductors, the clauses of this standard apply.
