Defines type, production and optional test on thyristor valves used in thyristor controlled reactots (TCR), Thyristor switched reactor (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. the requirements of the standard apply both to single valve units (one phase) and to multiple valve units (several phases). Clauses 4 to 7…

Defines the standard interface dimensions for the type LSH family of connectors. The parent connector for the type LSH connector family is a single-position plug connector which is characterized by a 2,5 mm. nominal ferrule diameter. It includes a push-click-pull coupling mechanism, which is spring-loaded relative to the ferrule in the direction of the optical axis. The optical alignment…

This International Standard establishes specifications for the stability of photographic films intended for storage of records; specifically, microfilms with a base of safety polyester [poly(ethylene terephthalate)] having predominantly silver behenate salts dispersed in nongelatinous emulsions, and thermally processed to produce a black-and-white silver image. This International Standard applies…

This National Standard of Canada is equivalent to International Standard ISO 14024:1999. 1 Scope This International Standard establishes the principles and procedures for developing Type I environmental labelling programmes, including the selection of product categories, product environmental criteria and product function charateristics; and for assessing and demonstrating compliance.…

1. SCOPe 1.1 These requirements cover hose nozzle valves that are intended to be used to control the flow of flammable and combustible liquids. They are of the type used in the assembly of motor fuel dispensing equipment. Valves covered by this Standard are for use with flammable and combustible liquids which are handled at temperatures within the range of -40°C to +50°C at a working pressure…

Defines the standard interface dimensions for the type FS connector family which is a duplex connector set of plug and adaptor configuration. The plug has a pair of cylindrical spring loaded abutting ferrules of 2,5 mm nominal ferrule diameter. The optical alignment mechanism is a rigid bore or resilient sleeve contained within the adaptor. It includes a hand-released latch coupling. The plug has…

1. Scope 1.1 This Standard provides requirements for polyethylene pipe, tubing, and fittings for use in gas mains and services, including gathering, transmission, and distribution applications, that carry fuel gases containing not more than 1% aromatic hydrocarbons. 1.2 This Standard also applies to all types of fittings and connections used in a plastic gas pipe system, including…

1. Scope 1.1 This Standard covers performance testing of socket- and saddle-type polyethylene electrofusion fittings that are used to join polyethylene pipe where the heat source is an integral part of the fitting. Note: Fittings covered by this Standard are connected to an electrical power source during the fusion process. Power sources, cables, and electrical connections are covered…
