International Standards and Conformity Assessment for all electrical, electronic and related technologies

August/September 2011

 

Nominations

Officers of IEC Consultative and Technical Committees

As well as its regular Technical Committees, the IEC has a number of Strategic Groups, Sector Boards and Technical Advisory Committees which report to the SMB (Standardization Management Board). This month, e-tech announces various changes and nominations.

ACEA
Advisory Committee on Environmental Aspects

ewaste

ACEA considers all aspects of the protection of the natural environment against detrimental impacts from a product, group of products or system that uses electrical technology, including electronics and telecommunications. EMC aspects are excluded as they are covered by ACEC (Advisory Committee on Electromagnetic Compatibility).

 

SMB approved the nomination of Richard Hughes to a second term on ACEA (Advisory Committee on Environmental Aspects). Hughes serves as a member of US TAGs (Technical Advisory Groups) to IEC TC (Technical Committee) 111: Environmental standardization for electrical and electronic products and systems, WG (Working Group) 1: Material declaration for electrical and electronic equipment. The second term runs from 1 August 2011 to 31 July 2014.

 

SMB approved the nomination of Bongjin Jung to a first term on ACEA. Jung serves as a member of IEC TC 111WG 1. The first term runs from 1 July 2011 to 30 June 2014.

ACOS
Advisory Committee on Safety

Medical equipment

ACOS deals with safety matters that are not specific to a single TC (Technical Committee). Its task is to guide and coordinate IEC work on safety matters to ensure consistency in IEC safety standards. Reporting to SMB, ACOS assigns horizontal and group safety functions to TCs to ensure this consistency.

 

SMB approved the nomination of Norbert Bischof to a third term on ACOS (Advisory Committee on Safety). Bischof serves on IEC TC 62: Electrical equipment in medical practice. The third term runs from 1 May 2011 to 30 April 2014.

 

Insulation

SMB approved the nomination of Preben Holm to a first term on ACOS as representative of IEC TC109: Insulation co-ordination for low-voltage equipment. The first term runs from 1 May 2011 to 30 April 2014.

TC 39
Electronic tubes

SMB has announced the nomination of Nam Je Koh to a second term as Chairman of IEC TC 39: Electronic tubes. The new term runs from 1 September 2011 to 31 August 2014.

 

IEC TC 39 prepares International Standards relating to electronic tubes, including integrated components and/or circuits. This also covers accessories with regard to their compatibility aspects. X-ray tubes are excluded.

Electronic tubes

 

The Committee’s scope covers several electronic tube technologies, e.g. receiving tubes, CRTs (cathode ray tubes) and magnetron tubes.

 

An electronic tube or vacuum tube is a sealed glass or metal-ceramic enclosure used in electronic circuitry to control the flow of electrons between the metal electrodes sealed inside the tubes. The air inside the tubes is removed by a vacuum. Vacuum tubes are used for amplification of a weak current, rectification of an alternating current to direct current (AC to DC), generation of oscillating radio-frequency (RF) power for radio and radar, and so forth.

TC 68
Magnetic alloys and steels

Micrograph soft magnetic alloy

SMB has announced the nomination of Hugh J. Stanbury to a fifth term as Chairman of IEC TC 68: Magnetic alloys and steels. The new term runs from 1 October 2011 to 30 September 2014.

 

The global magnetics and electrical engineering industries employ soft magnetic alloys and steels which are fundamental to the generation and distribution of electrical power, electrical machine and related technologies. At the other end of the spectrum of magnetic material behaviour are the magnetically hard compounds and alloys which are crucial for a large number of magneto-mechanical applications and some examples of technical energy transformation.

 

IEC TC 68 develops International Standards that address:

  • the classification and specifications of alloys and steels with regard to their magnetic and other physical properties which are relevant to their electrotechnical usage;
  • the methods by which those properties are determined, appropriate for practical normative use in industry and test laboratories, i.e. proven to show proper reproducibility and economic efficiency.
