This part of IEC 62435 is related to deterioration mechanisms and is concerned with the way that components degrade over time depending on the storage conditions applied. This part also includes guidance on test methods that may be used to assess generic deterioration mechanisms. Typically, this part is used in conjunction with IEC 62435-1 for any device long- term storage whose duration may be more than 12 months for product scheduled for long duration storage. Mechanisms that apply to specific component types are detailed in IEC 62435-5 to IEC 62435-9 (proposed).
