What is a Standard?
A standard is a document that prescribes or recommends performance, product characteristics, designs or management objectives. If you want more details you may want to read Standards Systems: A Guide for Regulators from the Standards Council of Canada.
Examples of Standards at Work
Standards are the reason that:
- A lightbulb made in China for GE fits in a socket made in Thailand for Phillips and works using North American power.
- A steam boiler won’t blow up when operated at specified temperature & pressures and will vent if it does exceed those specifications.
- It's possible to assemble a computer from components manufactured by many companies and to use software written by other companies and have it work.
- A test carried out by a lab in Vancouver is comparable to one done in Montreal.
- The cable pulling your elevator box up to the 10th floor doesn’t snap under a half load.
Standards might also be called Recommended Practices, Guidelines, or Military Specifications (aka Mil Specs).
Standards for buildings & construction are often called codes. However, other standards might be called codes, such as the ASME Boiler and Pressure Vessel code.
