According to the American Society of Mechanical Engineers (ASME), a standard can be defined as "a set of technical definitions, instructions, rules, guidelines, or characteristics set forth to provide consistent and comparable results, including:
Items manufactured uniformly, providing for interchangeability
Tests and analyses conducted reliably, minimizing the uncertainty of the results
Facilities designed and constructed for safe operation."
Engineering standards typically fall into three categories:
Limited consensus standards: developed by experts in a given organization and then made available to the organization for their guidance
General consensus standards: developed by experts to serve the need of a given industry; require substantial input from other interested parties
Governmental standards: produced by a wide range of governmental organizations and can be jurisdictional (legally enforced) or non-jurisdictional
A standard is typically represented by the acronym of the issuing organization followed by a number and date of issuance (e.g., ANSI B152.2-1982 or ISO 10096:1997).
