Pat Testing Association

Any appliance that has a plug that will be connected to a wall socket or generator needs PAT testing. All these various electrical appliances need to be PAT tested to ensure that they are safe to use. Each appliance goes through a visual inspection first followed by an earth continuity test, lead polarity and insulation resistance checks.

All electrical appliances are categorised into different classes which determines which appliances need PAT testing. Electrical appliances are categorised into class 1, 2 or 3.

Class 1 appliances are the most dangerous and require a full PAT test. Examples of Class 1 appliances are:

          Floor standing printers

          Desktop computers

          Industrial machinery

          Fridges

          Washing machines

          Kettles

          Irons

          Mobile phone chargers

          Tumble dryers

Class 2 appliances have extra insulation so they only require a PAT insulation test. Examples of Class 2 appliances are:

          Desktop printers

          Lamps

          Televisions

          Food mixers

          Hairdryers

          Hair straighteners

Class 3 electrical appliances are the least dangerous and do not require a PAT test at all. Their charging cables may need to be PAT tested. Examples of Class 3 appliances are:

          Laptops

          Mobile phone chargers

          Cameras
