ECA 186-2E
Passive Electronic Component Parts, Test Methods for; Method 2: Moisture Resistance (Cycling)
Organization:
ECIA - Electronic Components Industry Association
Year: 1978
Abstract: PURPOSE
This test is intended to evaluate in an accelerated manner, the resistance of component parts to deterioration resulting from high humidity and heat conditions typical of tropical environments. This test differs from the steady-state humidity test (Method i), deriving added effectiveness from temperature cycling. This provides alternate periods of condensation and drying essential to the development of corrosion process, and in addition produces a "breathing" of moisture vapor into partially-sealed containers. The test provides a time during which optional low temperature or vibration subcycles may be inserted for revealing the otherwise undiscernible evidences of deterioration.
