How long does PAT Testing take?

The item of equipment will need to be unplugged from its electric socket*, so obviously it will be out of use during the inspection and testing procedure. When working in offices, I typically inspect and test the equipment at one person's desk at a time, which allows everyone else to get on with their work undisturbed. Typically, the average office desk set-up with a computer, monitor, printer, table lamp, phone charger, extension lead, etc., will take about fifteen minutes to carry out all of the tests. Therefore, that person would be without her/his computer for that length of time. In the case of file servers, email servers, network switches/hubs and telecommunications equipment, etc. (which are only inspected/tested by me with the express permission of the client), this would obviously inconvenience all users for what would hopefully be a short period or time*. I can typically inspect and test around twenty-five items per hour (which includes smaller items such as power leads, etc.).

If suitable and convenient to both parties, and also if it doesn't invalidate the client's business insurance, the work could be carried out outside normal office hours. Again, express permission would have to be granted before working on 'system-critical' equipment.


* Having said this however, I may be able to carry out the important 'earth continuity' test on some of this equipment even when it is switched on and running, providing that there is a spare electric three-pin wall or extension lead socket very close by.
