A PAT test refers to the examination of portable electrical appliances to ensure they are safe to use.
An effective PAT testing programme helps identify faulty appliances before they can cause harm. Any equipment found to be defective must not be used until it has been repaired or replaced.
There are three main types of PAT tests:
-
User checks
-
Formal visual inspections
-
Electrical tests using specialised equipment known as a Portable Appliance Tester
The type of test chosen depends on the risk associated with each appliance. For example, appliances that are frequently moved or have metal casings are considered higher risk and may require more thorough testing.
