This International Standard defines how user oriented performance of computer-based software systems (CBSS) may be measured and rated. A CBSS is a data processing system as it is seen by its users, e.g. by users at various terminals, or as it is seen by operational users and business users at the data processing center. A CBSS includes hardware and all its software (system software and…

This International Standard specifies the essential dimensional requirements for size "S" fuel nozzles used in diesel engines. These requirements allow the assembly and interchangeability of the nozzles in the corresponding nozzle holders. This International Standard is applicable to size "S" nozzles, which comprise hole type, long-stem nozzles (types A1 and A2) and pintle…

This International Standard specifies requirements for fusion-bonded, epoxy-coated, or epoxy-coated and filled, seven-wire prestressing steel strand for the prestressing of concrete. NOTE Use of epoxy-coated strand in pre-tensioned applications such as fire-rated construction should be approached with caution.

This International Standard specifies a general procedure for the production, by injection-moulding, of tubular test pieces for the determination of the resistance to internal pressure. It also specifies the design of the mould to be used. By using the same material as for injection-moulded piping components, such as fittings, these test pieces make it possible to determine the time-related…

1 PURPOSE This standard specifies the physical and dimensional characteristics of prefabricated reinforced concrete and unreinforced concrete pipes and monolithic lateral connections. This standard also specifies control and test methods to verify these requirements. 2 SCOPE This standard applies to round sections of reinforced concrete and unreinforced concrete pipes intended for burial…

This National Standard of Canada is equivalent to International Standard ISO/TS 16949:1999 (first edition, 1999-03-01). 1. Scope This Technical Specification specifies, in conjunction with ISO 9001:1994, the quality system requirements for the design/development, production and, when relevant, installation and servicing of automotive-related products. This Technical Specification is…

This National Standard of Canada is based on International Standard CEI/IEC 1264:1994. 1 General 1.1 Scope This standard applies to hollow insulators made of ceramic metarial, with their fixing devices, intended for use with a permanent gas pressure greater than 0,5 bar having an internal volume equal to or greater than 1 litre (1 000 cm³). They are intended for use in electrical…

This National Standard of Canada is based on International Standard CEI/IEC 61230: 1993. 1 Scope This International Standard is applicable to portable equipment, with or without matching fixed connection points, for temporary earthing or earthing and short-circuiting of electrically isolated a.c. transmission and distribution systems, including railway systems, for the protection of…

This International Standard specifies a method for determination of water up to 25 % in petroleum products, bitumens, tars and products derived from these materials, excluding emulsions, by the distillation method. The specific products considered during the development of this test method are listed in Table 3. This International Standard may be used to determine water content in excess of 25…
