© 2009 A C PAT Testing Services
The frequency of the PAT testing is based upon the chance of the appliance being damaged in use. So this depends on the design of the appliance (Class I or Class II), on how easy it is to move (stationary, handheld etc) and also on where it is used (office, school, construction site etc). The table below gives some guidelines.
