PAT testing definition: PAT testing, is the ‘abbreviated’ version of the correct term of Portable Appliance Testing, also known as “PAT Inspection” or “PAT Testing“. It is the name given to a process of inspection and testing by which electrical appliances are routinely checked for safety.
PAT testing is carried out in the United Kingdom, Republic of Ireland, Australia and New Zealand.
Health and Safety regulations require electrical appliances to be safe, and to undergo regular maintenance to prevent accident or incident at work.
Equipment manufacturers tend to recommend testing at particular intervals to ensure continual safety. The intervals between tests depends on the type of appliance and the environment in which it is used.
Portable appliance testing is commonly abbreviated to “PAT”, however the correct term for the process is “In-Service Inspection and Testing of Electrical Equipment”.
British law requires all electrical installations (including portable appliances) to be maintained to prevent danger (more information on portable appliance testing law).
