1. Scope 1.1 This Standard applies to manually operated and mechanically operated special use switches that are: (a) for use on dc, ac/dc or ac only; and (b) rated for not more than (i) 60A at 250V or less; or (ii) 30A or 2hp at 600V or less. 1.2 This Standard does not apply to (a) switches forming parts either of electrothermal appliances or automatic temperature-responsive switches; (b)…

Describes the measurements of the appropriate hardness where only medium precision is required. The method and apparatus used are essentially those described in ISO 7619, the measurements in this case being made on the curved surface. Shore-type A and D instruments are specified, the latter being used for measurements on rollers of high hardness. Part 1 and 3 of this standard deal with the IRHD…

1. Scope 1.1 This Standard specifies the mechanical, dimensional and electrical requirements for ceramic and glass type station post insulators for indoor or outdoor service in electrical installations or equipment operating with a rated voltage greater than 1000 V and a rated frequency not greater than 100 Hz. 1.2 This Standard covers insulators intended primarily for use as support…

1. Scope 1.1 This Standard applies to insulated conductors intended for use in power-operated electronic devices and is issued to supplement clauses dealing with conductors in CSA Standard C22.2 No. 1. 1.2 The voltage rating of any type of wire covered by this Standard is governed by the requirements of CSA Standard C22.2 No. 1.

1. Scope 1.1 This Standard applies to single and multiple conductor fire alarm and signal cables for use in buildings in dry or damp locations having a nominal voltage rating of 300 V or less and a minimum temperature rating of 60°C for use in accordance with the Rules of Sections 16 and 32 of the Canadian Electrical Code, Part I. 1.2 All constructions suitable for use as fire alarm…

1. Scope 1.1 This Standard applies to central warm air electric resistance type furnaces which are either incorporated in a solid fuel fired furnace or are attached to a solid fuel fired furnace, so as to form a single unit which can be used as an electric furnace, a solid fuel fired furnace, or both simultaneously if so designed. 1.2 This Standard applies to electric furnaces in…

1. Scope 1.1 This Standard applies to mineral-insulated cables with copper, nickel-clad copper, or nickel conductors, enclosed in a copper or stainless steel sheath. 1.2 The constructions covered by this Standard are intended for use in power, instrumentation, control, and fire alarm systems in accordance with the Rules of the Canadian Electrical Code, Part I. 1.3 The…

1. Scope 1.1 This Standard specifies the requirements for air conduction pure tone audiometers used in determining the hearing threshold level of an individual in comparison with the standard reference threshold levels. These audiometers may be manual, automatic recording, or computer controlled. This Standard does not include requirements for sweep-frequency audiometers and excludes…

Specification of dimensions of and requirements for the twelfe most commonly used forms of steel and carbide finishing burs to ensure the interchangeability of these instruments. Other characteristics of bur heaeds, for example spiralled blades or cross-cut, are not covered by this standard. Attention is drawn to the number coding system of ISO 6360 which specifies a 15 digit number for…
