Guide to International Standards Publications

The following is a list of standards, publications, and other resources that may be of use to the International Design Engineer. Major sources of documents and publications which we believe are pertinent to the Interpower Corporation product lines are also noted.


AEA (American Electronics Association) — Washington D.C. Office, 601 Pennsylvania Avenue, N.W., North Building, Suite 600, Washington, DC 20004. Telephone: (202) 682-9110. Fax: (202) 682-9111.Santa Clara Office, 5201 Great America Parkway #520, Santa Clara, CA 95054-1120. Telephone: (408) 987-4247. Fax: (408) 986-1247. American Electronics Association is an association for the high-tech industry. www.aeanet.org.


ANSI (American National Standards Institute) — 25 West 43rd Street 4th floor, New York, NY 10036. Telephone: (212) 642-4900. Fax: (212) 398-0023. www.ansi.org. ANSI is an organization composed of many special working groups that concentrate on particular technical areas. U.S. representation at the IEC is organized through ANSI. In addition, ANSI is a major distributor of North American and international publications, such as VDE, DIN, IEC, and others.

BSI (British Standards Institution) — BSI is a major information source. BSI offers excellent reference materials on electrical and electronic standards worldwide. In addition, they have translated many foreign standards into English which are available for purchase. For information, contact BSI Group HQ, 389 Chiswick High Road, London W4 4AL, United Kingdom. Telephone: +44 (0) 208 996 9000. Fax: +44 (0) 208 996 7001. www.bsi-global.com.• Suggested BSI references:
BS 546: This standard describes a grounded plug system with three round contacts oriented in triangular geometry. BS 546 specifies three different connectors for ratings of 2, 5, and 15A. These connectors are not intermateable because both contact diameters and spacing increase with the increasing current rating. BS 546 is being replaced by BS 1363. However, the 15A rated connector, currently the basis for the Indian standard, is used in several African countries, and in Malaysia on air conditioning units.

BS 1362: Defines the parameters for a fuse that is installed in all British plugs conforming to BS 1363 (see below).

BS 1363: This standards document describes a grounded primary power connector system with solid rectangular contacts. The plug is always fused, and the rating is 13A. This is the current British standard, and it is used in countries like Malaysia for circuits rated up to 13A.

CEN/CENELEC [Comité Européen de Normalisation Electrotechnique (European Committee for Electrotechnical Standardization)] — 35 Rue de Stassartstraat, B-1050 Brussels, Belgium. Telephone: (32) 2 519 6871. Fax: (32) 2 519 6919. www.cenelec.org.The CEN/CENELEC 28 member countries include Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Hungry, Germany, Greece, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, and the United Kingdom. The goal of CEN/CENELEC is to remove trade barriers among its members. After a very complicated standards writing process, which usually revolves around existing IEC standards, an EC Directive is issued. This results in documents called “ENs” (European Norms) and “HDs” (Harmonizing documents). All members are required to accept their use, instead of their own national standards. One special certification scheme for cables and cords illustrates the effect very well. When cable is certified and marked HAR, it is mandatory for all member countries to accept its use, regardless of what member country actually did the certifying. Thus, a trade barrier is removed.• Suggested CENELEC references:

IEC (International Electrotechnical Commission) — 3, Rue de Varembé, P.O. 131, CH-1211, Geneva 20, Switzerland. Telephone: (41) 22 919 02 11. Fax: (41) 22 919 03 00. www.IEC.ch.IEC writes and distributes consensus standards created through an elaborate network of worldwide committees made up of experts in the areas of concern. In effect, an IEC standard is a treaty, signed by many nations to foster international standardization. The standards on electrical products and components include references to safety and performance. The IEC does not perform any testing; this function is left to the national testing agencies. National standards are frequently based on IEC publications. Inquiries regarding IEC standards may also be made to the U.S. National Committee of the IEC, American National Standards Institutes (see previous reference to ANSI for address).• Suggested IEC references:

IECEECB Scheme is the same as the old CEE—CB Scheme that issued CEE standards. This is a worldwide program for reciprocal recognition of safety testing results of electrical equipment, among participating countries. Over 30 countries now have membership on the IECEE, including Japan, all members of CEN/CENELEC, and some Eastern European countries. The IECEE is headquartered at the IEC, in Geneva (see IEC for address). A bulletin covering many issues including national deviations from the IECEE standards is available from the IEC. www.cbscheme.com.
