4. TESTING ORGANIZATIONS AND ITS COMMITTEE
ASTM International, formerly known as American Society for
Testing and Materials, is an international standards
organization that develops and publishes voluntary consensus
technical standards for a wide range of materials, products,
systems, and services.
Some 12,575 ASTM voluntary consensus standards operate globally.
A group of scientists and engineers, led by Charles Dudley, formed
ASTM in 1898 to address the frequent rail breaks affecting the fast-
growing railroad industry.
The group developed a standard for the steel used to fabricate rails.
ASTM International has offices in Belgium, Canada, China, Peru,
and Washington, D.C.
5. ASTM International predates other standards organizations such
as the
1. BSI (1901), British Standards Institution
2. IEC (1906), International Electrotechnical Commission
3. DIN (1917), German Institute for Standardization
4. ANSI (1918), American National Standards Institute
5. AFNOR (1926), French Standardization Association
6. ISO (1947). International Organization for Standardization
6. BSI (1901), British Standards Institution
BS 12 Specification for Portland Cement
BS 37 Specification for Electricity Meters
BS 49 Specification for Ammeters and Voltmeters
BS 56 Definitions of Yield Point and Elastic Limit
BS 499 Welding terms and symbols.
7. IEC (1906), International Electrotechnical Commission
IEC prepares and publishes international standards for
all electrical, electronic and related technologies – collectively
known as "electrotechnology".
IEC standards cover a vast range of technologies from power
generation, transmission and distribution to home appliances
and office equipment, semiconductors, fibre optics,
batteries, solar energy, nanotechnology and marine energy as
well as many others.
All electrotechnologies are covered by IEC Standards, including
electronics, magnetics
and electromagnetics, electroacoustics, multimedia, telecommu
nication and medical technology.
8. DIN (1917), German Institute for Standardization
DIN 476: international paper sizes (now ISO 216 or DIN
EN ISO 216)
DIN 1451: typeface used by German railways and
on traffic signs
9. ANSI (1918), American National Standards
Institute
The programming language COBOL had ANSI standards in
1968, 1974, and 1985.
The original standard implementation of
the C programming language was standardized as ANSI
X3.159-1989, becoming the well-known ANSI C.
10. AFNOR (1926), French Standardization
Association
The AFNOR Group develops its international standardization
activities, information provision, certification and training
through a network of key partners in France who are members
of the association. They are:
ACTIA (Association of Technical Cooperation for the
food industry)
ADEME (French Agency for Environment and Energy
Management)
ADEPT (Association for the development of international trade
in food products and techniques)
CSTB (Scientific and Technical Center for Construction)
CTI (Center Network industrial technology)
11. ISO (1947). International Organization for
Standardization
ISO is a voluntary organization whose members are recognized
authorities on standards, each one representing one country.
A council with a rotating membership of 20 member bodies
provides guidance and governance, including setting the annual
budget of the central secretariat.
The technical management board is responsible for more than
250 technical committees, who develop the ISO standards
ISO/IEC Guide 65:1996 General requirements for bodies
operating product certification
ISO/PAS 11154:2006 Road vehicles — Roof load carriers
