Requirements for Enclosures

• Usage of an IEC 62208 enclosure or

• Design Verification

• Resistance against corrosion

- Damp heat cycling (IEC 60068-2-30)

- Saltspray test (IEC 60068-2-11)

• Resistance to heat

- Dry heat test plus cloth ribbing and normal heat (IEC 60068-2-2, -2-10)

- Glow-wire test (IEC 60695-2-10) or pre-selection

• UV radiation (ISO 4892-2)

• Lifting per 10.2.5

• Mechanical Impact (IEC 62262)

• IP rating (IEC 60529)




IP testing IEC 60529 for IPX5 waterjet

Slide 10




Why do we need to repeat tests already

conducted at component level ?• Test with components are mainly done without an enclosure

• Usage within a specific enclosure may change test results (more

difficult or less difficult).
