Why do washing machines fail PAT testing?
Why do washing machines fail PAT testing?
The most common reason why equipment often appears to fail a leakage test is that an incorrect limit is used. Some equipment is designed to operate with a leakage higher than the 5mA limit. Because there is a risk of an electric shock if the protective conductor becomes disconnected, extra precautions are required.
What happens if a PAT test fails?
What if an appliance fails a PAT test? Items that actually fail tests are usually removed from service with immediate effect, and supervisors, contractors and users suitably notified.
When carrying out leakage tests What should you always ensure?
It can be used as an alternative to the insulation resistance test when it can’t be performed. When carrying out this test and using rotating machinery such as drills and grinding machines, always secure the appliance so that when the power is applied the appliance will not cause injury.
Why do things fail PAT test?
Any cracks or damage to the plug, or excessive damage to the appliance itself that may expose it’s electrics will fail. A cracked or damaged plug, could potentially be an electric shock risk when the end user is removing or plugging in the item.
Can I do PAT testing myself?
Yes, your business can carry out its own PAT tests, as long as the person doing the testing is a ‘competent’ person. If you decide to do your own PAT testing we would strongly recommend taking a PAT testing course as it’s important to perform the PAT tests correctly.
What does PAT testing actually test?
A PAT test is a routine inspection of some types of electrical appliance to check they are safe to use. Its purpose is to prevent electrical accidents in the workplace. This test includes earth continuity, lead polarity, and insulation resistance checks.
Can you PAT test washing machine?
Stationary equipment is basically things such as fridges, washing machines and other appliances that stay in a fixed position for most of their life cycle. It may look big and bulky and basically the opposite of portable, but stationary equipment is still part of the PAT testing procedure.
How do you do a leakage test?
- Step 1 : Remove the spark plugs and rotate the engine to put the cylinder to be tested at TDC.
- Step 2 : Figure out which spark plug adapter works best and connect the gauge into the hole.
- Step 3 : Record leakage percentage for the cylinder.
Who is responsible for PAT testing?
Those responsible for having PAT testing done include anyone who uses electrical equipment as well as administrators with responsibility for electrical maintenance who may or may not have detailed technical knowledge.
Can I PAT test myself?
In theory, yes, you can PAT test without a qualification. Guidance says you have to be ‘competent’ to test electrical equipment, not that you have to be qualified. The Portable Appliance Testing Trade Association say that you should undergo thorough training by a competent person in order to become competent yourself.
