Information sources: Standards


Standards are intended to ensure compatibility between products and appliances from different suppliers. They are produced by both national and professional organisations.

Most countries in western Europe have a national organisation, which is responsible for standards, eg AFNOR in France, DIN in Germany and the British Standards Institution (BSI). In the USA, there is both a national body, the American National Standards Institute (ANSI), and also professional bodies each with its own standards, eg. the American Society for Testing Materials (ASTM). There is also an international body for standards, the International Standards Organisation (ISO).
