This National Standard of Canada is based on International Standard ISO 8835-4:2004. 1 Scope IEC 60601-1:1988, Clause 1 applies except as follows. Addition: This part of ISO 8835 specifies particular requirements for the essential performance of anaesthetic vapour delivery devices (AVDDs), as defined in 3.1. This part of ISO 8835 is applicable to AVDDs which are a component of an anaesthetic…

1 Scope 1.1 This Standard covers the features of three-phase submersible transformers rated 75 to 3000 kV.A. Note: For details not covered herein, reference should be made to CSA C2.1. 1.2 This Standard applies only to three-phase distribution transformer units intended for use in a ventilated vault or enclosure below grade level, with all terminations and accessories cover mounted, or nearly…

1 Scope 1.1 This Standard covers the features of single-phase submersible transformers rated 25 to 333 kV'A. Note: For details not covered herein, reference should be made to CSA C2.1. 1.2 This Standard applies only to single-phase distribution transformer units intended for use in a ventilated vault or enclosure below grade level, with all terminations and accessories cover mounted, or…

This National Standard of Canada is based on International Standard CEI/IEC 61000-3-11:2000. 1 Scope and object This part of IEC 61000 is concerned with the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system. It specifies the limits of voltage changes produced by equipment tested under specified…

ISO 6149-1:2006 specifies dimensions for metric ports for use with the adjustable and non-adjustable stud ends detailed in ISO 6149-2:2006 and ISO 6149-3:2006. Ports in accordance with ISO 6149-1:2006 may be used at working pressures up to 63 MPa (630 bar) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon port size, materials…

Determines the suitability of solderless crimped connections under specified mechanical, electrical and atmospheric conditions and provides a means of comparing test results when the tools used to make the connections are of different designs or manufacture.

ISO 6149-3:2006 specifies dimensions, performance requirements and test procedures for metric adjustable and non-adjustable light-duty (L series) stud ends and O-rings. Stud ends in accordance with ISO 6149-3:2006 may be used at working pressures up to 40 MPa (400 bar) for non-adjustable stud ends and 31,5 MPa (315 bar) for adjustable stud ends. The permissible working pressure depends upon the…

ISO 6149-2:2006 specifies dimensions, performance requirements and test procedures for metric adjustable and non-adjustable heavy-duty (S series) stud ends and O-rings. Stud ends in accordance with ISO 6149-2:2006 may be used at working pressures up to 63 MPa (630 bar) for non-adjustable stud ends and 40 MPa (400 bar) for adjustable stud ends. The permissible working pressure depends upon the…

ISO 7240-12 specifies requirements, test methods and performance criteria for line type smoke detectors for use in fire detection systems installed in buildings. The detectors consist of at least a transmitter and a receiver and can include reflector(s), for the detection of smoke by the attenuation and/or changes in attenuation of an optical beam. This part of ISO 7240 does not cover line-type…

Covers particular requirements for surge arresters for specific use in fixed installations of d.c. traction systems. They consist of one or more non-linear resistors which may be in series with single or multiple spark gaps. Covers also low-voltage limiters, that is protective devices mainly used in fixed installations of d.c. traction systems to connect certain portions of the circuit.
