Electrical safety testing has been implemented and enforced for one reason: to protect consumers from potentially fatal electric shock. These tests are performed to ensure that products, including anything from household electric coffee makers to hairdryers and computers meet industry standards for construction, performance, ratings, markings and instruction manuals.
Not only do manufacturers want to prevent faulty components from being installed in their products, but they also want to catch workmanship defects in assemblies before installation. Following a proper safety testing procedure can help to identify production problems before a product is shipped preventing costly recalls and embarrassing public announcements. Still other manufacturers test to protect themselves from product liability suits. Whatever the reason may be, electrical safety testing makes good sense for any consumer product manufacturer.
