development and delivery of international voluntary consensus
standards. Today, some 12,000 ASTM standards are used around the
world to improve product quality, enhance safety, facilitate market
access and trade, and build consumer confidence.
ASTM’s leadership in international standards development is driven by
the contributions of its members: more than 30,000 of the world’s top
technical experts and business professionals representing 150
countries. Working in an open and transparent process and using
ASTM’s advanced electronic infrastructure, ASTM members deliver the test methods, specifications,
guides and practices that support industries and governments worldwide.
The International Electrotechnical Commission (IEC) is the world’s leading
organization that prepares and publishes International Standards for all
electrical, electronic and related technologies. Over 10 000 experts from
industry, commerce, government, test and research labs, academia and
consumer groups participate in IEC Standardization work.
Globally relevant!
The IEC is one of three global sister organizations (IEC, ISO, ITU) that
develop International Standards for the world. When appropriate, IEC
cooperates with ISO (International Organization for Standardization) or ITU
(International Telecommunication Union) to ensure that International Standards fit together
seamlessly and complement each other. Joint committees ensure that International Standards
combine all relevant knowledge of experts working in related areas.
The Bureau of Indian Standards (BIS) is the national Standards Body
of India working under the aegis of Ministry of Consumer Affairs, Food
& Public Distribution, Government of India. It is established by the
Bureau of Indian Standards Act, 1986 which came into effect on 23
December 1986.
The organization was formerly the Indian Standards Institution (ISI),
set up under the Resolution of the then Department of Industries and
Supplies No. 1 Std.(4)/45, dated 3 September 1946. The ISI was registered under the Societies
Registration Act, 1860.
