NEC 40 treedt op als schaduwcommissie van IEC/TC 40, CLC/TC 40XA en CLC/TC 40XB. Voor de volledigheid hieronder taak en werkgebied van deze commissies.
IEC TC 40: Capacitors and resistors for electronic equipment:
To prepare international standards for :
a) Capacitors, resistors, thermistors and varistors intended for use in electronic equipment.
b) Capacitors, resistors and inductors and complete electromagnetic interference (EMI) suppression filter units for EMI suppression (see note).
c) Passive integrated circuits or networks containing resistors, capacitors, inductors or their combinations. For the dimensional standardization of the final package, requirements laid down by TC 47 shall be adopted whenever possible.
d) Packaging of electronic components for automatic handling, which is an activity undertaken on behalf of all relevant component technical committees.
e) Electric double layer capacitors for use in electrical and electronic equipment.
Note : In this work, use is to be made as far as possible of any relevant work of TC 51 on inductors, and of the CISPR on the measurement of radio interference suppression characteristics. Liaison is also to be maintained with TC 61 and other appropriate IEC Technical Committee on the safety aspects of Radio interference suppression components and filter units.
CLC/TC 40XA: Capacitors and EMI suppression components
To prepare European standards, which are required to facilitate the trading activities of European component users and manufacturers, in the following areas:
a) capacitors, fixed and variable, for use in electronic equipment;
b) capacitors, resistors and inductors, and combinations of these, used for electro-magnetic interference suppression, and complete electro-magnetic interference suppression filter units;
c) networks and passive integrated circuits containing capacitors, or combinations of resistors, capacitors and inductors.
CLC/TC 40XB: Resistors
To prepare and maintain European Standards in the field of fixed and variable resistors and networks for use in electronic equipment.
These standards are for use within a suitable system for quality assessment of electronic components, and aim to support the trading activities of European component users and manufacturers.
