VME are unable to undertaking Portable Appliance Testing for individual items through to complete equipment inventories at schools, offices, theatres etc.
All our PAT testing conforms to the latest IEE guidelines.
A visual inspection of the equipment is carried out, along with an electrical test, comprising of the following:
(i) Earth bond continuity tests
(ii) Insulation resistance testing
(iii) Functional checks
(a) Earth Bond Test (Class 1 equipment only):
Readings should show less than 0.1+R Ohms (where R is the resistance of the lead)
Tested at a current of 1.5 times the rating of the fuse and no greater than 25A for a period of between 5 and 20 seconds or with a short-circuit test current within the range 20mA to 200mA.
(b) Insulation Resistance Test:
The applied test voltage should be approximately 500 Vdc
Class 1 heating equipment < 3kW 0.3M Ohms
Class 1 All other equipment 1M Ohms
Class 2 Equipment 2M Ohms
Class 3 Equipment 250k Ohms
(c) Optional Tests:
Flash Test: No flashover or breakdown shall occur
Operation/Load test: Compare reading with stated details on nameplate
Earth leakage test:
Class 1 Handheld Appliances 0.75mA
Other Class 1 Appliances 3.5mA
Class 2 Appliances 0.25mA
We are able to offer the most competitive rates for PAT testing, and guarantee to beat any like-for-like quotation.
