What is electrical safety testing?
Testing electrical and electronic products for electrical safety is intended to identify the potential risk of electrical shock to users. Evaluating a product for electrical safety usually includes the following tests:
- High voltage test (dielectric withstand test) - measures the ability of an electrical product to withstand a high voltage applied between a product’s electrical circuit and ground.
- Leakage current test - evaluates whether current that flows between an AC source and ground does not exceed a specified limit.
- Insulation resistance test - calibrates the quality of the electrical insulation used.
- Ground continuity test - ensures that a clear path is available between all exposed metal surfaces and the power system ground.
In addition to pre-market testing and certification, manufacturers of electrical and electronic products must also conduct production line testing. Depending on certification requirements, production line testing may include some or all of the tests required for certification.
Why is electrical safety testing important?
In addition to achieving compliance with the relevant directives, regulations and standards, full or partial testing of electrical and electronic products and devices enables manufacturers to meet customer requirements. Electrical safety is mandatory for legal access to every major country in the world. It can help prevent unsafe products from reaching the market, reducing the number of deaths and injuries, as well as costly product recalls and potential litigation. Manufacturers whose products that have been tested and certified to applicable electrical safety standards send a clear signal to buyers and the general public of their commitment to user safety.
