1.1 This part of ISO 8257 establishes a system of designation for poly(methyl methacrylate) (PMMA) thermoplastic materials, which may be used as the basis for specifications. 1.2 The types of PMMA plastics are differentiated from each other by the classification system based on appropriate levels of the designatory properties a) Vicat softening temperature, b) melt mass-flow rate, c) viscosity…

1.1 This International Standard establishes a system of designation for filament yarns of carbon fibre which may be used as the basis for specifications. 1.2 This designation system is applicable to filament yarns used for the reinforcement of polymer composites. It does not apply to discontinuous fibre products pyrolized in the form of staple yarns, woven fabrics, braids, knits, mats, etc. 1…

1.1 Scope This Standard applies to the safety of tungsten filament lamps intended for use in lighting equipment, designed to be installed on branch circuits not exceeding 750 V and used in accordance with the rules of the Canadien Electrical Code (CEC), Part I. Note: Manufacturers designing products for use in Canada may find a helpful summary of the equipment-related requirements of…

The recommendations of this technical report are applicable to electrical and electronic equipment with a rated input current exceeding 16 A per phase and intended to be connected to public low-voltage a.c. distribution systems of the following types: - nominal voltage up to 240 V, single-phase, two or three wires; - nominal voltage up to 600 V, three-phase, three or four wires; - nominal…

This part of ISO/IEC 13719 specifies PCTE in abstract, programming-language-independent, terms. It specifies the interface supported by any conforming implementation as a set of abstract operation specifications, together with the types of their parameters and results. It is supported by a number of standard bindings, i.e. representations of the interface in standard programming languages. The…

Is applicable to two-pole voltage detectors to be used on electrical systems for nominal voltages not exceeding 1 000 V a.c. and/or 1500 V d.c and below 500 Hz (nominal frequencies). The detector types are classified as follows: voltage class A: up to and including 500 V a.c./750 V d.c.; voltage class B: up to and including 1 000 V a.c./ 1 500 V d.c. Low-voltage detectors covered by this…

1. Domaine d'application 1. Cette norme vise les émetteurs radio électriques conçus pour être alimentés par des circuits d'alimentation standard conformément au Code canadien de l'électricité, Première partie. Comprend tous les émetteurs radio quel que soit le type de modulation.

1. Scope 1.1 This Standard applies to factory-made automatic ice-makers with a capacity between 23 and 1000 kg/d (measured at standard rating conditions). These machines produce cube, flake, crushed, or fragmented ice in either a batch or continuous process, as defined in Clause 2. They are electrically operated and designed for a 60 Hz operating current with nominal nameplate voltage…

1. Scope 1.1 This Standard applies to commercial refrigerator, refrigerator-freezer, and freezer cabinets that are intended for storing or holding food products and other perishable merchandise. 1.2 This Standard applies to (a) manufacturers' standard catalogue-type equipment; (b) closed cabinets of the unitary, self-contained type; (c) commercial refrigerated storage cabinets,…
