Testing and approval of electrical appliances

The paper describes the development of the Electricity Council Appliance Testing Laboratories, formerly known as the EDA Testing House, and surveys the various schemes associated with the approval of electrical appliances and accessories in the UK. The relationship with international standardising bodies is explained, and the tests specified in the British Standards are compared with those of the international CEE specifications. The extent to which the British and international standards have been brought into agreement is shown.
