Portable Appliance Testing - Frequency

There is no specific schedule set out. There are however guidelines to help. The frequency of testing depends on the type of equipment and the environment in which it is used. For example a high-risk item such as an electric drill should be tested more frequently than a low risk item such as a PC. Furthermore a drill that is used everyday in a high density manufacturing plant should be tested more frequently than a drill used only occasionally in an office environment.
