Recording results. While there is no legal requirement to record your ‘PAT Test’ results, it is seen as good practice. Whether you use a test device with a data logging facility, an app on a tablet, or good old pen and paper, this is your way of demonstrating due diligence.
If there was an incident, which is investigated, you can show that you have a maintenance schedule in place and also what condition the equipment was in at its last check. Obviously the condition can change, but on that day it was okay.
It also allows you to see if there has been any deterioration in the item. Has it needed a repair since last time? Have the test results got worse? Has the item changed location into an unsuitable area? If we are being thorough, a ‘PAT Test’ looks at the bigger picture, not just a narrow snap-shot.
