Why Standards Matter

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.

Standards can help us:

  • better understand the required specifications for products
  • ensure products, systems, services behave reliably and safely
  • learn how something works (treat standards as “how-to” instructions)
  • meet safety criteria required by law
