Method for the determination of the proof and the comparative tracking indices of solid insulating m...
Specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. The standard provides for the determination of erosion when required. Test results cannot be used directly for the evaluation of safe creepage distances when designing…
Methods of measurement for radio equipment used in the mobile services - Part 5: Receivers employing...
Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using single-sideband amplitude modulation. The standard is intended to be used in conjunction with IEC 489-1.
Methods of measurement for radio equipment used in the mobile services - Part 3: Receivers for A3E o...
Deals with the definitions, the conditions and the methods of measurement used to ascertain the performance of receivers having audio-frequency bandwidths generally not exceeding 10 kHz for the reception of voice and other types of signals, using angle modulation (phase/frequency modulation), or
double-sideband amplitude modulation with full carrier. This standard is intended to be used in…
Deals with sound level meters of four degrees of precision, designated Types 0, 1, 2 and 3. Specifies the following characteristics: directional characteristics, frequency weighting characteristics, time-weighting, detector and indicator characteristics, sensitivity to various environments. Establishes electrical and acoustical tests to verify compliance with characteristics specified and…
Methods of measurement for radio transmitters. Part 7: Cabinet radiation at frequencies above 1 GHz
Specifies the method which is essentially the same as that described in CISPR publication 11, sub-clause 5.2.2. With this method, emphasis has been laid on simplicity and reproducibility, rather than on rigorous scientific method. lt has been purposely developed for use in an ordinary laboratory room to avoid the use of an expensive anechoic room. The method is intended for type tests but it may…
Three-Phase, Dead-Front, Pad-Mounted Distribution Transformers
1. Scope
1.1 This Standard covers the features of three-phase dead-front pad-mounted distribution units consisting of transformer and cable entrance compartment with provision for separable insulated high-voltage connectors. For other details, reference s hall be made to CSA Standard C2, Single-Phase and Three-Phase Distribution Transformers, Types ONAN and LNAN.
1.2 The rated kVA…
Applies to the grammage of fine papers, expressed in grams per
square metre (g/m2). Standard grammages for various types of fine
papers are as shown in Appendix A in grams per square metre.
Appendix B lists the grammages with the former basis weights they
are intended to replace and the latter's equivalent in g/m2.
