What Is PAT Testing Mainly Used For?

Typical portable electrical home equipment found in a workplace embrace drills, hair dryers, vacuum cleaners, buffing machines, energy saws, photocopiers and laptops, to name but a couple of! Electrical items that aren't considered to be portable home equipment include things like ceiling lamps and cookers that are hard-wired into the mains supply.

There isn't any legal requirement as such in UK law to PAT test electrical equipment, however it does come beneath well being and safety law, within the type of the Electrical energy at Work Rules 1989. These rules require all electrical systems, including items of portable electrical equipment, to be maintained so they do not grow to be dangerous. PAT testing is a technique to meet this requirement. There is not any authorized timeframe as to when appliances needs to be tested and at what intervals, but many employers test appliances on an annual basis, or more frequently if they're exposed to harsh conditions (e.g. used outdoor or in moist, scorching or cold environments).

Ultimately, the frequency of testing must be decided by a risk evaluation for every merchandise of equipment. Risk assessments are a legal requirement, in accordance with the Management of Well being and Security at Work Rules 1999. An excellent danger assessment for a chunk of portable gear must determine the main risks from using the gear, to identify items at a higher threat of losing their integral security by injury, misuse or degradation. The danger assessment should also put in place control measures to minimise risk. PAT testing is one instance of a management measure to decrease risk. The higher the risks identified in the threat evaluation, the more ceaselessly PAT tests ought to be carried out, together with different management measures to lower risk.

The actual testing procedure for portable appliances features a visual inspection, as well as a test using a particular PAT testing instrument. The visible test ought to check the condition of cables and wires, integrity of the casing and the plug. PAT test instruments carry out more detailed checks on equipment. Mains powered PAT testing Padstow testers are used, as well as battery operated testing devices. These are self-contained and straightforward to use. They carry out an earth continuity test, insulation resistance test and a check on the wiring of the mains cord. They'll additionally include tests that energy up the appliance so it can be tested when linked to the mains supply. Most testing machines use a straightforward pass or fail result. As well as their pass and fail message, they have completely different settings for metal and plastic appliances, analysing earth continuity, polarity and insulation resistance.

More advanced PAT testing machines are available and are able to provide more detailed information about the appliance, with more subtle testing features. These are primarily aimed at more complex portable appliances with a higher factor of risk when used at work. Advanced PAT testing devices display more information than a simple pass or fail message. Their earth continuity resistance test gives a more refined measurement vary and might address lower test currents, which enables a wider vary of appliances to be tested (e.g. computers, which are sensitive to regular PAT testing). They will also carry out insulation resistance tests at voltages of 500 V DC and 250 V DC, earth leakage tests, fuse tests and lead polarity tests.

Of course, all outcomes from a PAT test should be interpreted by someone who's competent to do so. Competency is outlined in well being and security legislation as having adequate information, training, expertise and experience to hold out a certain activity correctly and safely. Visual inspections might be carried out by the equipment customers themselves. Electricians should pass stringent examinations to qualify for their trade and the readings from an official PAT test must be interpreted and logged, which is normally greatest carried out by an electrician or somebody who as sufficient talent and time to get round even the most important of workplaces. PAT testing makes up an necessary part of services management because it will possibly document the location and safety status of portable electrical equipment. Most giant employers contract out their PAT testing to an electrical contractor on an annual basis, to an organization like Fluke Ireland.
