ME 340: Mechanical Engineering Design Methodology

Course Guide to support the product design course.

Standards Explained

A Standard is Defined by the National Standards Policy Advisory Committee as:

A prescribed set of rules, conditions, or requirements concerning definitions of terms; classification of components; specification of materials, performance, or operations; delineation of procedures; or measurement of quantity and quality in describing materials, products, systems, services, or practices.

How are Standards Developed?

  • Usually in response to a request from industry or stakeholders, such as consumer groups.
  • They are drafted by a panel of international experts within a technical committee.
  • All aspects of the standard, including scope, key definitions and content, are negotiated by the panel.
  • Development is through formal stages of drafting and consultation, aimed at achieving consensus and maximum stakeholder input.

Is it a Standard, a Code, or a Regulation?

  Properties Example
Standard A standard is a technical publication created to ensure the reliability of the materials, products, methods, and/or services. Standards are not mandatory by law. The Universal Serial Bus
Type-C Cable and Connector
Specification.
Code A code is a type of standard that is adopted and enforced by one or more governmental agencies. Unlike a general industry standard, a code MUST be followed when it has been adopted into law in a specific geographical/political region or when it has been included in a contractual agreement. The National Electrical Code (NFPA-70) is an example of this type of standard. Every state in the United States adopted it to protect people from electrical hazards.
Regulation A regulation is a type of standard that has been mandated by law. Regulations specify legally obligated requirements that must be met under specific laws and implement general agency objectives. Occupational Safety and Health Administration (OSHA) Regulations.
