1 Scope 1.1 This Standrd applies to corrugated electrical nonmetallic tubing (ENT) and mechanically-attached fittings, for use in accordance with the Canadian Electrical Code, Part I (CE Code, Part I), and the ANSI/NFPA 70 National Electrical Code (NEC), in nonhazardous locations. These requirements also apply to mechanically-attached fittings integral with an outlet box. 1.2 Products…

This National Standard of Canada is equivalent to International Standard CEI/IEC 1000-1-1:1992 1 Scope The object of this report is to desribe and interpret various terms considered to be of basic importance to concepts and practical application in the design and evaluation of electromagnetically compatible systems. In addition, attention is drawn to the distinction between electromagnetic…

This National Standard of Canada is equivalent to International Standard CEI/IEC 1000-2-1:1990. 1 Scope This section of IEC 1000-2 is concerned with conducted disturbances in the frequency range up to 10 kHz with an extension for mains signalling systems. Separate sections give numerical compatibility levels for different system voltage levels. This section does not deal with the application…

This National Standard of Canada is based on International Standard CEI/IEC 1000-2-2:1990. 1 Scope This section of IEC 1000-2 is concerned with conducted disturbances in the frequency range up to 10 kHz with an extension for mains signalling systems. This section gives numerical compatibility levels for low voltage a.c. distribution systems with a nominal voltage up to 347 V, single-…

This National Standard of Canada is equivalent to International Standard IEC 300-2:1995. 1 Scope This Part of IEC 300 describes the elements of a dependability programme and gives guidance on the selection of tasks necessary to achieve specified dependability of products. This standard cross-references and complements ISO 9004-1. It is applicable to hardware and systems containing…

This National Standard of Canada is equivalent to International Standard IEC 300-3-9:1995. 1. Scope This section of IEC 300-3 provides guidelines for selecting and implementing risk analysis techniques, primarily for risk assessment of technological systems. The objective of this standard is to ensure quality and consistency in the planning and execution of risk analyses and the presentation…

This National Standard of Canada is equivalent to International Standard ISO 14040:1997. 1 Scope This International Standard specifies the general framework, principles and requirements for conducting and reporting life cycle assessment studies. This International Standard does not describe the life cycle assessment technique in detail.

The object of this technical report is to give general information about the systems of plugs and socket-outlets for household and similar purposes which are used in the IEC countries. The report only contains National Systems which are commonly used in homes and offices. It is therefore limited to systems for a.c. with a rated voltage above 50 V but not exceeding 440 V, intended for household…

This Technical Report (type 2) aims at providing advice on methods for developing climatic load databases. This is necessary for the implementation of IEC 60826 which provides the framework for National Standards on overhead line design.

1.1 SCOPE 1.1.1 This standard applies to manually-operated gas valves (see Part IV, Definitions), hereinafter referred to as valves, not exceeding 4 inches (102 mm) pipe size, and pilot shut-off devices (see Part IV, Definitions), hereinafter referred to as devices. Except for hose end valves not intended for permanent connection to a hose, and appliance…
