What Is Portable Appliance Testing?
Portable Appliance Testing or as it is more commonly known as PAT testing, involves a process of periodically inspecting and testing of electrical equipment or appliances to ensure they are safe for use.
Firstly all appliances will receive a formal visual inspection to ensure both the flexible cable and the appliance are free from wear and tear, damage, signs of burning, plug tops are also opened to ensure correct wiring, correct fuse rating and again free from damage or signs of overheating.
Providing the appliance successfully passes the formal visual inspection, the appliance will then be subjected to a series of electrical tests depending on its classification; all testing will be performed by a PAT tester with a valid calibration certificate.
Equipment passing both the formal visual inspection and testing will be clearly labelled with a PASS label containing a unique asset number, test date, re-test date and engineer's initials.
Equipment failing either the formal visual inspection or testing will be clearly labelled with a FAIL label containing a unique asset number, test date, engineer's initials and reason for failure. The appliance will also be removed from service and reported to your nominated responsible person.
In order to maintain standards all testing performed will be in accordance with the IET's Code of Practice for In-service Inspection and Testing of Electrical Equipment 4th edition.
