This is a question that we probably get asked most often.
Making sure an electrical appliance is safe to use is Law - although PAT Testing does not exist in legal terms as it is a slang term.
The Law states that it is a Duty Holder's responsibility to check to make sure that ALL electrical systems are of such construction and are maintained as a practicable step to prevent danger. The Electricity at Work Regulations (1989) Sec. 4 and other Legislation reiterates this.
There is a lot of misinformation on the internet so all we need to do is to point you directly to :
The Electricity at Work Regulations 1989 (sec.4). sec 4-6 refers to InspectionThe Electricity at Work Regulations 1989 (sec 8) sec 7-8 refers to inner conductors including the integrity of the earthing conductor and sufficient insulation which would require a test.There is no denying that formal inspections and electrical testing is required but the Health and Safety Executive only state that appliances must be safe to use and will not tell anybody how to to it but offer suggestions and guidance.
Formal Inspections are necessary to check if an item of
electrical equipment is of such construction for continued use. (Usually skipped by a lot of providers as it takes time to open plug tops)
Testing is necessary to ensure that the safety features incorporated at the time of manufacture such as 'Earth Bonding' and 'Insulation' are there throughout the working life of an electrical appliance.
This should be carried out to equipment that is likely to be
In-service between inspections/tests.
So if you look back at the highlighted words you will see:
In-service, Inspections, Testing, Electrical Equipment.
The IET (Institution of Engineering and Technology) has a Code of Practice which ALL 'PAT Testing' Companies should follow as it is considered best practice.
The IET Code of Practice for in-service Inspection and Testing of Electrical Equipment (5th Edition).Although it is usual for the Duty Holder to ask a 'PAT Testing' company to carry this out on their behalf it is ALWAYS the responsibility of the Duty Holder to ensure that it is being carried out correctly and fully itemised and detailed inspection/test results should be issued by the provider so that the 'responsible person' can interpret results and determine ongoing frequencies based on risk...not the PAT Testing Company.
