A standard is an agreed and repeatable way of doing something. A standard is a collective work that is created by bringing together the expertise and experience of all interested parties, such as manufacturers, sellers, buyers, users and regulators of a particular material, product, process or service. Standards are designed for voluntary use and do not generally impose any regulation, but some laws and regulations may refer to standards and even make compliance with them compulsory. There are many different types of standards ranging from British Standards to labelling standards such as the Fairtrade trade mark,  the Forest Stewardship Council Standards mark and the European Flower mark.
