The IET Code of Practice for In-service Inspection and Testing of Electrical Equipment 5th Edition is the definitive guide to inspection and testing of portable electrical appliances in the UK. Anyone carrying out PAT testing should have a copy ready for consultation.

Featuring a larger emphasis on electrical equipment within the workplace, specifically items such as air-conditioning units and security access control systems not covered by other maintenance regimes. New appendices are included with sections providing guidance for low-risk equipment, example risk assessments, basic electrical theory primers and more.

As the portability of an item is irrelevant to an equipments safety, the fifth edition of the IET Code of Practice removes long-standing terminology including ‘portable’ and ‘appliance’ except in explanatory notes.

Reference information is included on:

  • Legislation
  • Hand-held equipment
  • Surge Protected devices
  • Testing procedures
  • Common faults
  • Risk based assessments
  • Pass and fail levels
  • Frequency of inspection
  • Formal visual inspections
