2. 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

3. 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.

4. 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.

5. 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

6. 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.

7. 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.

9. Standards development steps
