  4. 4. Implementing and practicing the bestInternational Standards & ReferencesASTM International, formerly known as the American Society for Testingand Materials (ASTM), is a globally recognized leader in thedevelopment and delivery of international voluntary consensusstandards. Today, some 12,000 ASTM standards are used around theworld to improve product quality, enhance safety, facilitate marketaccess and trade, and build consumer confidence.ASTM’s leadership in international standards development is driven bythe contributions of its members: more than 30,000 of the world’s toptechnical experts and business professionals representing 150countries. Working in an open and transparent process and usingASTM’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 leadingorganization that prepares and publishes International Standards for allelectrical, electronic and related technologies. Over 10 000 experts fromindustry, commerce, government, test and research labs, academia andconsumer groups participate in IEC Standardization work.Globally relevant!The IEC is one of three global sister organizations (IEC, ISO, ITU) thatdevelop International Standards for the world. When appropriate, IECcooperates with ISO (International Organization for Standardization) or ITU(International Telecommunication Union) to ensure that International Standards fit togetherseamlessly and complement each other. Joint committees ensure that International Standardscombine all relevant knowledge of experts working in related areas.The Bureau of Indian Standards (BIS) is the national Standards Bodyof India working under the aegis of Ministry of Consumer Affairs, Food& Public Distribution, Government of India. It is established by theBureau of Indian Standards Act, 1986 which came into effect on 23December 1986.The organization was formerly the Indian Standards Institution (ISI),set up under the Resolution of the then Department of Industries andSupplies No. 1 Std.(4)/45, dated 3 September 1946. The ISI was registered under the SocietiesRegistration Act, 1860.
