A standard is a technical document designed to be used as a rule, guideline, or definition. Standards are published documents that establish specifications and procedures designed to ensure the reliability of the materials, products, methods, and/or services people use every day. They are fundamental building blocks for product development by establishing consistent protocols that can be universally understood and adopted.
Standards are created by bringing together all interested parties such as National organizations, Professional Societies, Manufacturers, Consumers, and Regulators of a particular material, product, process, or service.
All parties benefit from standardization through increased product safety and quality; and lower transaction costs and prices—ensuring product functionality and compatibility, facilitating interoperability, and supporting safety.
In summary, standards fuel the development and implementation of technologies that influence and transform the way we live, work, and communicate.
