Portable Appliance Testing Explained

The term PAT generally refers to in-service inspection and testing of portable appliances.

Electrical appliances are built to specific standards and these appliances undergo Type Approval Tests and the Production Line Tests by the manufacturer before they reach the customer to ensure that they conform to the required standards.

PAT testing is essentially a repeat of the electrical safety tests that were carried out at the time the product was built. It is a periodic in-service electrical safety inspection and test to ensure that the electrical safety of the appliance is not compromised while the equipment is in service.

A typical PAT test will include inspection and some of the following tests:

- Visual
- Earth Bond
- Insulation
- Load and Earth Leakage
- Touch Leakage
- Polarity
- Substitute Leakage
- Flash
