A standard is a published document that contains a technical specification or other precise criteria. These are designed to be used consistently as a rule, guideline, or definition in order to increase the reliability and the effectiveness of the products and services we use. Standards are created by bringing together the experience and expertise of all interested parties such as the producers, sellers, buyers, users and regulators of a particular material, product, process or service.
Subject coverage of standards collections includes science, technology and business service specifications. The collection is updated daily and 2,000 new or revised standards are added annually to ensure that technical content is current. Many international standards are implemented into British Standard, if this is the case then it will clearly say it, i.e. BS EN ISO.
