Portable Appliance Testing (PAT)
The frequency of inspection and testing required for each piece of equipment will vary depending on the following:
- The environment:
- Equipment in a benign environment is likely to suffer less damage than equipment in an arduous environment.
- The users:
- If users report damage promptly hazards will be avoided. Conversely, if equipment is likely to receive unreported abuse, more frequent inspection & testing is required.
- The equipment construction:
- The safety of Class 1 equipment is dependent upon a connection with earth. Class 2 equipment is not dependent upon a fixed earth.
- The equipment type:
- Appliances that are hand-held are more likely to be damaged than fixed appliances.
The following table provides guidance on the initial frequencies of inspection and testing, however, the frequency must depend upon the factors listed above, and should be kept under constant review.
