"A standard can be defined as a set of technical definitions and guidelines that function as instructions for designers, manufacturers, operators, or users of equipment." - ASME

"A redline version of a standard indicates the changes made, during the standards revision process, between the active standard and its previous version." - IEEE

Standards are documents that describe the important features of a product, service or system. For example, CSA Standard Z262.34-00 Ice Hockey Pucks specifies a hockey puck's material, size, mass, hardness at room temperature and test methods.

Why use standards?

"Because it’s a catastrophe when a screw doesn’t fit." - ASME

Standards help to ensure quality of products, safety of consumers and interchangabilty of parts.  Use of standards can help companies improve their profit margins and customer satisfaction.  There may also be important ethical reasons to use standards when creating a design.
