ASME CODES & STANDARDS
ASME BACKGROUND
Founded: 1880
120,000 individual members; no corporate members
<400 staff
Not-for-profit organization
Focused on technical, educational and research issues
One of the world’s largest technical publishing operations
Holds numerous technical conferences worldwide
Offers professional development courses
Sets internationally recognized industrial and manufacturing codes and standards that enhance public welfare and safety
WHAT IS A STANDARD?
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.
Standards, not having the force of law, are considered
voluntary and serve as guidelines. ASME publishes
standards and accredits users of standards to ensure that
they are capable of manufacturing products that meet
those standards.
WHAT IS A CODE?
A standard is a code when it has been adopted by one or more governmental bodies and is
enforceable by law, or when it has been
incorporated into a business contract.
ASME CODES AND STANDARDS
ASME’s Codes and Standards organization develops and maintains standards and conformity assessment programs
First standard issued in 1884
Approx. 600 consensus standards
Over 100 ASME standards committees
Over 3,600 volunteer committee members
Standards address pressure technology, nuclear, safety, standardization, and performance test codes
Conformity Assessment programs to accredit manufacturers of equipment
ASME CODES AND STANDARDS
ASME’s Voluntary Consensus Process
Openness, balance of Interests, consensus, due process
American National Standards Institute (ANSI) accredited procedures
Compliance with World Trade Organization (WTO) Technical Barriers to Trade (TBT) principles for international standards development
Transparency, openness, impartiality and consensus, effectiveness and relevance, coherence, and development dimension.
HOW DOES ASME PRODUCE CODES AND STANDARDS?
ASME’s Council on Codes and Standards oversees six standards-developing supervisory boards and three advisory boards, which manage more than 100 committees and 3,600 volunteer members (see figure on next page).
The supervisory boards are responsible for pressure technology, nuclear installations, safety codes, performance test codes, conformity assessment, and standardization.
The advisory boards deal with international standards, hearings and appeals, and council operations.
