ISO 4126-3:2006 specifies the requirements for a product assembled from the in-series combination of safety valves or CSPRS (controlled safety pressure relief systems) according to ISO 4126-1, ISO 4126-4 and ISO 4126-5, and bursting disc safety devices according to ISO 4126-2 installed within no more than five pipe diameters from the valve inlet. It specifies the design, application and marking…

This National Standard of Canada is based on International Standard CEI/IEC 61000-3-3:1994 +A1 :2001. 1 Scope This part of IEC 61000-3 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods…

1 Scope 1.1 This Standard specifies the electrical requirements for safe interconnection of inverter-based micro-distributed resource (micro-DR) systems to low-voltage systems connected to distribution systems. The output of these systems is limited to 600 V (nominal) or less (single or three phase). 1.2 Intentional islanding conditions and interconnection to secondary networks are not…

Object The object of the Code is to specify requirements for the installation and maintenance of electrical equipment to help ensure safe electrical installation. The electrical safety of industrial and similar installations is also ensured through compliance with the objective-based fundamental safety principles of IEC 60364-1 through the implementation of a quality management program or…

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.
