What is PAT Testing?

Portable Appliance Testing (commonly known as PAT or PAT Inspection or PAT Testing) is a process in the United Kingdom by which electrical appliances are routinely checked for safety.

Do I need a PAT test?

If you can answer YES to any of these questions then YES you do!

  1. Are you an employer using portable appliances?
  2. Do you employ more than 5 employees?
  3. Do you carry out health and safety risk assessments?
What checks do PAT testers do?

One of the main checks that is required is a visual check, this contains a list of checks that are essential before an electrical test can be performed.

  • check that plug has no cracks
  • look for signs of overheating
  • check that flexible cable is properly secured in the cord anchorage
  • check the plug has been correctly connected
  • check that the cable screws are tight and secure and no loose strands
  • check the rating of the fuse and make sure it is securely gripped
  • check that the fuse(BS 1362), plug(BS 1363) and ASTA mark is shown
  • check the cable length and equipment in use for damage

When these visual checks have been done then a sequence of electrical tests are performed.
