Re: PAT testing - Is it legally required new [Re: Kendo Phil]

One precaution I took at my last but one employer was not to use my normal initial..Still my name! But I included the first letter of my middle name.

Since I was testing 100 or so production items a month I did not want anything coming on top with my monica forged on it!

Dave.

One thing to add (sorry if someone already has lots of replys here) is that I must say the testers do work in many situations where a visual test alone wouldn't have found the fault. Just in case some people might think they are a waste of time. Besides the obvious one of the earth connection hanging on by a single strand - passing the high current through burns it out and you get the fail - there is also the insulation test. The tester puts a high voltage across the connections and can spot many potential problems such as a hairline crack in the insulation of the wires, esp where they have rubbed on a chassis screw or fitting. There might be no connection, but the high voltage arcs across revealing the potential trouble. Of course you still have to use your eyes to find the fault, which can take awhile!, but at least you have confidence in it once it passes.

Some equipment might not like the insulation test, but I think most high voltage stuff would benefit from it. Not even sure if it's part of the PAT "test", even though the testing equipment can do it.
