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 toensure 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, per formance test codes, conformity assessment, andstandardization.

The advisory boards deal with international standards, hearings and appeals, and council operations.

Standards development steps Initiate Standards Action Prerequisite technical work, R&D Draft standard – project team Distribute to cognizant groups for review

and comment Standards Committee approval Public review Supervisory Board approval ANSI approval
