When Carrying out Portable Appliance testing (PAT) an example method statement is as follows:-
- Arrive at client premises, identify PAT Tester to Reception and sign in if required.
- Conduct appliance/cable testing in methodical and logical manner.
- Inform PC users or Network Administrator in advance when testing IT equipment.
- Place” tested” sticker onto each item and record unique number into the asset register.
- Inform users/management of any items that fail testing; these items are to be removed from use immediately.
General Checks Carried Out:-
- check that plug has no cracks
- look for signs of overheating
- check that flexible cable is properly secured in the cord anchorage
- check the plug has been correctly connected
- check that the cable screws are tight and secure and no loose strands
- check the rating of the fuse and make sure it is securely gripped
- check that the fuse( BS 1362), plug( BS 1363) and ASTA mark is shown
- check the cable length and equipment in use for damage
When these visual checks have been done then a sequence of electrical tests are performed
Class 1 Appliances (Example:- Kettles, Toasters, Irons, Microwaves, Electric Heaters and Fridges)
- earth continuity test
- insulation resistance test
- dielectric strength test
- protective conductor current test
- wiring polarity check/functional checks
Class 2 appliances (Example:- Televisions, DVD Players, Lamps and Power Tools)
- insulation resistance test
- dielectric strength test
- touch current test
- functional checks
