Essential PAT Testing procedures:

1. Preliminary Visual Inspection to check for visible defects

•Damaged or incorrectly wired plugs
•Non-British Standard or incorrect value of fuse
•Damaged cables or switched/controls
•Sub-standard connection of cable to appliance
•Damage to appliance case

2. Earth bond Test (Class I equipment only)

•To test the integrity of the protective earthing circuit. (The appliance is connected to a portable appliance test machin to check the continuity resistance of the protective circuit is within IET tolerances)

3. Insulation Resistance Test

•To test the integrity of the insulation of the appliance between the live and protective earth parts of the appliance
•The appliance is subjected to 500V DC between the phase and neutral conductors connected

4. Load/operation Test

•To verify that the appliance is working safely and does not have excessive leakage
N.B.: Other tests may be carried out as necessary, as specified by the IET (Institution of Engineering and Technology) Code of Practice
