PAT Testing

Cambs-PAT provides testing that is carried out under the IEE's Code of Practice for In-Service Inspection and Testing. This testing includes all electrical equipment as detailed in the IEE Code of Practice. The test process consists of:

Visual Inspection:
- Flex inspected for damage to ensure it is free from cuts, fraying or stress. - Plug opened to ensure that the flexible cable is secure and correctly wired, that the fuse is of the correct rating for the appliance, free from any sign of overheating and in physically good condition.

- The Appliance is inspected to ensure that it is in good working order, including ensuring that it switches on and off properly and that there is no damage that could result in access to live parts.

- Polarity Test (carried out on extension cables and supply leads)

- Earth Continuity Test (not carried out on Class II appliances that have no earth)

- Insulation Resistance Test - Operational Test (if possible)

- Earth Leakage Test (if Operational Test carried out)

- A bar-coded label will be attached to each appliance that passes its testing.

- Appliances that fail testing will be labeled DO NOT USE Failed Safety Test.

- A full-colour, comprehensive register of all equipment tested on the premises. This means that you comply with regulation 29 of the Electricity at Work Regulations (1989)
