How do I test class I equipment with no exposed conductive parts?

There may be instances where class 1 equipment has no exposed earthed metal parts, which makes the earth continuity test impossible to carry out.

The device under test cannot be tested as Class II equipment. The test should be carried out as  normal but the earth continuity test should be emitted, and then a supporting comment recorded in the results. The duty holder must then alter the risk assessment relating to this item.

The manufacturer will always remain the ultimate authority on testing its products so can seek guidance from the manufacturer.
