Applies to electrical and/or electronic equipment that have a rated input current up to 16 A per phase. Aims to establish a reference for evaluating the immunity of electric and/or electronic equipment when subjected to positive and negative low amplitude voltage fluctuations. Only conducted phenomena are considered, including immunity tests for equipment connected to public and industrial power…

Establishes a reference for evaluating the immunity of electric and electronic equipment when subjected to variations of the power frequency. Only conducted phenomena are considered, including immunity tests for equipment connected to public and industrial networks. This consolidated version consists of the first edition (1999) and its amendment 1 (2001). Therefore, no need to order amendment in…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61000-4-16:1998 (first edition, 1998-01), including Amendment 1:2001. 1 Scope This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment to conducted, common mode disturbances in the range d.c. to 150 kHz. The object of this standard is to establish a…

Is applicable to portable phase comparators with or without a built-in power source to be used on electrical systems for voltages from 1 kV to 36 kV a.c. and frequencies from 50 Hz to 60 Hz. This standard is applicable to two-pole phase comparators having a connecting lead between them, two-pole phase comparators operating with a wireless connection and single-pole phase comparators operating…

This part of ISO 727 specifies the dimensions of plain sockets (cylindrical and conical) in fittings made from unplasticized poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride) (PVC-C) or acrylonitrile/butadiene/styrene (ABS), intended for connecting by solvent cementing to pipes of the corresponding material for use under pressure. The resulting joint does not require mechanical…

This part of ISO 727 specifies the dimensions, in millimetres, of plain sockets (cylindrical and conical), for the inch-based pipe series, in fittings made from unplasticized poly(vinyl chloride) (PVC-U), chlorinated poly(vinyl chloride) (PVC-C) or acrylonitrile/butadiene/styrene (ABS), intended for connecting by solvent cementing to pipes of the corresponding material for use under pressure. The…

This Recommendation | International Standard specifies the Enhanced Communications Transport Protocol (ECTP), which is a transport protocol designed to support Internet multicast applications over multicast-capable IP networks. This Recommendation | International Standard specifies the ECTP for the simplex multicast transport connection that consists of one sender and many receivers. This…

Gives guidance and explanatory comments on the existing procedures for lightning and switching impulse testing of power transformers to supplement the requirements of IEC 60076-3. Also generally applicable to the testing of reactors (see IEC 60289), modifications to power transformer procedures being indicated where required. Information is given on waveshapes, test circuits including test…
