International Standard Publications

The following list of standards, publications and other sources is intended as an assistance for the design engineer working internationally. This list also includes important documentation and publications, which - we think - are important for the product programme of our customers.

ANSI is an organisation composed of many special working groups that concentrate on particular technical areas. U. S. representation at the IEC is organised through ANSI. In addition, ANSI is a major distributor of North American and international publications, such as VDE, cDIN, IEC and others.

BSI, the British Standards Institution.
BSI is a major information source, offering a special division called the Technical Help to Exporters (“THE”) and Technical Information Group. Both BSI and THE offer excellent reference materials on electrical and electronic standards worldwide. In addition, they have translated many foreign Standards into English which are available for purchase.

Suggested BSI/THE 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. In the Interpower Components Limited‘s Designer‘s Reference & Catalogue, this type of plug is referred to as the “Old British” system.

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.

BS 4491:
This standard describes appliance connectors for household and similar general purposes. Several amendments to this standard have been published. Parts of this standard have been replaced by EN 60320.

BS 6500:
Standard on insulated flexible cords. Cross reference with IEC 60227, CENELEC HD21 and 22.

The CEN/CENELEC member countries include Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Sweden, Spain, 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” (Harmonising 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.
