Deals with essential ratings and characteristics of semiconductor devices and general principles of measuring methods. This publication is intended to be used in conjunction with IEC 147-1 and 147-2.
Nominal cross-sectional areas and composition of conductors of insulated cables
Specifies standardized nominal cross-section areas from 0.5 mm2 to 2 000 mm2, numbers and diameters of wires and resistance values of conductors in electric cables and flexible cords.
Classifies conductors for:
1) Cables for fixed installations
- Class 1, solid conductors;
- Class 2, stranded conductors.
2) Flexible copper conductors
- Class 5,
- Class 6 (more flexible than…
Lays down the conditions and procedure for carrying out impulse tests on cables and their accessories, with a view to rationalizing the practice in different laboratories, and thus to facilitate valid comparisons between the results obtained on cables made to different specifications.
Notes:
1.This publication should be read in conjunction with IEC 60060 and 60141.
2.For voltage measurements…
Fixe les conditions et les modalités d'essais de choc des câbles et de leurs accessoires en vue d'uniformiser la pratique des différents laboratoires et de faciliter les comparaisons valables entre les résultats obtenus sur des câbles répondant à des spécifications différentes.
Note:
1. Cette publication doit être lue conjointement avec les CEI 60060 et 60141.
2. Pour la mesure des…
Gives dimensions and tolerances for electronic tube and valve bases, holders and caps, together with the relevant gauges and gauging procedure, to ensure interchangeability. Also includes recommended practice for the preparation of drawings of electronic tubes and valves. This is a loose-leaf publication and supplements, containing new or revised sheets, are issued from time to time.
