Hi, I am doing a bit of work for a landlord & he has asked whether i would pat test a few of his flats. I always pat test the fixed appliances as well and quote accordingly when testing a cooker especially if it earth leakage i only put on one of the rings at a time and test so as not to overload kt71 pat tester. But i need to test storage heaters would i best using my multifunction & testing earth continuity & IR rather than pat tester

Cheers

I'm sorry I'm not the greatest of PAT testers but what do you mean you turn one ring on at a time, I thought that all appliances must be isolated to do testing.

Hi, Quite new to pat testing myself, dont really want to do it, but i have been getting asked for it. If the cooker contains electronics, earth leakage test (live test) putting on all the rings or all rings & oven may take it over 3 kw to much for test instrument. So as storage heater usually contain no electronics could i just multifunction? Cheers

I think you mean if the storage heater is on an off peak supply well how do you test it so as it is a fixed appliance you would have to disconnect it at the switch on the wall fine if you are an electrician but if you are a PAT tester you are not authorised or insured for this.This would be the same with the cooker.

You have touched on a sensitive subject here as there is problems within the PAT industry with regards to testing fixed appliances
 
Again I maybe wrong here, but I thought the Earth leakage test which is associated with electric strength test was a manufacturing test and is not needed in a normal PAT testing regime

I was taught to conduct this test instead of IR where the unit contain electronic equipment such a microwave. I also maybe wrong!!

Class I = Earth Bond and IR Test.
Class II = Insulation Test.

You can optionally do a flash test (if you have the equipment to do it and understand the consequences of getting it wrong!). It is generally recommended to do an operational test at the appropriate voltage (230/110).

Class II insulation test yet I get told most guys do a visual as the tester links out L&N and then references the test to earth or have I got this wrong?

No that's spot on mate. You are checking the L+N together against the case (and want a high reading), usually at 500V(DC).

Portable appliance testing is for portable items of equipment not cookers and storage heaters the clue is in the portable bit

Emmmm no actually it has been ISI&TEE (formally PAT) since last year because people are saying the same thing of the phrase Portable Appliance Testing is only for portable equipment the problem is the ISI&TEE COPs says otherwise. HSE have commissioned a report into the industry because of this so whats the problem well I&T covers fixed wiring and ISI&TEE covers all electrical equipment the only problem is that guys who are PAT tester trained only are not (and never will be) authorised or insured to open up FCU,cooker switches etc. Yes this is a headache but as usual it will be the insurance companies who get thing changed

Surely it has always been called In-Service Inspection and Testing of Electrical Equipment as that is what it says on the cover of the Code of Practice. PAT is a slang term which is used - can't say it was ever an official term certainly for a long time now.

Portable Appliance Testing Testing (PAT Testing) is just what people know it as? I do the testing on one of the clubs near by and they get all the fixed stuff tested too but it's all on the MF tester visual etc, IR and continuity. There's provisions for portable, fixed, hand held and movable now isn't there?

Yep I agree thats what I meant to say is that the lecturer of the ISI&TEE course I went on was telling us that the term PAT has now taken hold to urban myth status and this is causing much hand ringing as the Schemies are just ignoring it whilst as he says it is non compliance with the COP not to test fixed appliances plus he said the colleges were asked to certify PAT testers to do this equipment and it was a straight no and there lies the problem the Schemies have sold and promoted PAT for non electricians who now find they can only part of it. He reckons that there will be a relaunch this year to eradicate the term PAT
