1. l 1 4 Introduction to Product Safety Testing 1 4 1 The Importance of Safety Testing Product Safety Tests are specified during the design and development stages of a product as well as in the production of the products to insure that it meets basic safety requirements These tests are designed to verify the safety of the electrical products in that they do not jeopardize the safety of the people domestic animals and property of anyone who may come in contact with these products In an era of soaring liability costs original manufacturers of electrical and electronic products must make sure every item is as safe as possible All products must be designed and built to prevent electric shock even when users abuse the equipment or by pass built in safety features To meet recognized safety standards one common test is the dielectric voltage withstand test Safety agencies which require compliance safety testing at both the initial product design stage and for routine production line testing include Underwriters Laboratories Inc UL the Canadian Standards Association CSA the International Electrotechnical Commission IEC the British Standards Institution BSI the Association of German Electrical Engineers VDE and TUV the Japanese Standards Association JSI These same agencies may also require that an insulation resistance test and high current ground bond test be performed 1 5 The Different Types of Safety Tests
