IEC 61462:2023 applies to composite hollow insulators consisting of a load-bearing insulating tube made of resin-impregnated fibres, a housing (outside the insulating tube) made of elastomeric material (for example silicone or ethylene-propylene) and metal fixing devices at the ends of the insulating tube (see Figure D.1 and Figure D.2 for examples). The object of this document is to define the…

1 Scope This International Standard specifies requirements and tests for cable cleats used for securing cables in electrical installations and for intermediate restraints used for holding cables together in formation in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This document includes cable cleats that rely on a mounting surface…

1 Scope 1.1 Inclusions This Standard establishes methods of testing and rating for constant volume and/or variable refrigerant flow gas-fired, heat pumps for space-conditioning performance. These methods apply to factory-made, space-conditioning, unitary heat pumps that use gasoline as the primary fuel. This Standard applies to engine-driven heat pumps, absorption-cycle heat pumps, desiccant-…

1 Scope 1.1 Applications This Standard applies to the construction, performance, and installation procedures for a newly produced automatic damper device (referred to as “device” in this Standard) constructed entirely of new and unused parts and materials, and designed to be used with a gas-fired appliance listed by a nationally recognized certification body. 1.2 Inclusions This Standard…

Scope This National Standard of Canada applies to two types of automotive fuel: type 1, 50% to 85% by volume denatured fuel ethanol with gasoline and type 2, 20% to 25% by volume denatured fuel ethanol with gasoline. Both types are for use in flexible-fuel vehicles over a wide range of climatic conditions. Users of this standard are advised to consult the owner’s manual and/or the original…

Objet La présente Norme nationale du Canada s’applique à deux types de carburant pour véhicules automobiles : le type 1, constitué de 50 % à 85 % en volume d’éthanol-carburant dénaturé avec de l’essence et le type 2, constitué de 20 % à 25 % en volume d’éthanol-carburant dénaturé avec de l’essence. Les deux types sont destinés aux véhicules polycarburants utilisés dans des conditions…

This document specifies requirements for materials used in vulcanized rubber seals for the following: a)       cold drinking-water supplies (up to 50 °C); b)       drainage, sewerage, and rainwater systems (continuous flow up to 45 °C and intermittent flow up to 95 °C). The different designations of seals specified are defined according to their type, application, and requirements (see Table 5).…
