An example of a nationally recognised qualification of competence in PAT testing is offered by City & Guilds: 2377-77 Level 3 Award in the In-service Inspection and Testing of Electrical Equipment (603/6790/8), [21] while the current (2023) guidance is the 'Code of Practice for In-service Inspection and Testing of Electrical Equipment – 5th ...
The main advantage of a three-point flexural test is the ease of the specimen preparation and testing. However, this method has also some disadvantages: the results of the testing method are sensitive to specimen and loading geometry and strain rate.
All countries have their own electrical safety standards that must be complied with. To meet to these standards, electrical products and installations must pass electrical safety tests. Some types of electrical safety tests include: dielectric withstand test (also called a hipot test) insulation resistance test (IR test) earth continuity test ...

Values for the flexural strength measured with four-point bending will be significantly lower than with three-point bending., [8] Compared with three-point bending test, this method is more suitable for strength evaluation of butt joint specimens. The advantage of four-point bending test is that a larger portion of the specimen between two ...
Electrical equipment is important to be safe because apart from the obvious danger of causing electric shocks, faulty electrical equipment such as electric blankets can cause fires. Where fires have been caused by domestic electrical appliances, they are examined at the laboratory to determine what caused the fire.
The Izod impact test differs from the Charpy impact test in that the sample is held in a cantilevered beam configuration as opposed to a three-point bending configuration. The test is named after the English engineer Edwin Gilbert Izod (1876–1946), who described it in his 1903 address to the British Association , subsequently published in ...
