2 Scope and field of application 2.1 Type of equipment This Standard applies to fusion welded wrought aluminium and aluminium alloy enclosures pressurized with dry air, inert gases, eg, sulphur hexafluoride, carbon tetrafluoride, or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally…

2 Scope and field of application 2.1 Type of equipment This Standard applies to fusion welded wrought steel enclosures pressurized with dry air, inert gases, eg, sulphur hexafluoride, carbon tetrafluoride, or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric and/or…

2 Scope and field of application 2.1 Type of equipment This Standard applies to welded composite enclosures of cast and wrought aluminium and aluminium alloy enclosures pressurized with dry air, inert gases, eg, sulphur hexafluoride, carbon tetrafluoride, or nitrogen or a mixture of such gases, used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the…

This part of ISO 11126 specifies requirements for staurolite abrasives, as supplied for blast-cleaning processes. It specifies ranges of particle sizes and values for apparent density, Mohs hardness, moisture content, conductivity of aqueous extract and water-soluble chlorides. The requirements specified in this part of ISO 11126 apply to abrasives supplied in the "new" condition only.…

This International Standard specifies two test methods for determining the refractive index of plastics, namely: Method A: a refractometric method for measuring the refractive index of moulded parts, cast or extruded sheet or film, by means of a refractometer. It is applicable not only to isotropic transparent, translucent, coloured or opaque materials but also to anisotropic materials. The…

1.1 This part of ISO 9327 covers the technical delivery conditions for forgings (see note 1) and for rolled or forged bars for pressure purposes manufactured from the following internationally used steels (see note 2): a) non-alloy and alloy ferritic or martensitic steels with specified room temperature properties and supplementary requirements for elevated temperature properties covered in ISO…

This International Standard describes the operating principles and the most important performance characteristics of automated flow-measuring systems for determining the volume flowrate in the ducts of stationary sources. Procedures to determine the performance characteristics of automated volume flow-measuring systems are also contained in this International Standard. The performance…

1 Scope B45.0-99 1.1 This Standard applies to the following plumbing fixtures: (a) bathtubs; (b) kitchen and bar sinks; (c) lavatories; (d) laundry tubs; (e) shower enclosures and receptors; (f) drinking fountains and water coolers; (g) water closets; (h) bidets; (i) urinals; (j) non-recirculating toilets and waste-holding tanks for use in recreational vehicles; and (k)self-…

1. Scope 1.1 This Standard applies to macerating/pumping systems that collect waste from a single water closet, lavatories, and/or bathtubs located in the same room, and that grind these macerated wastes and pump them to some point in the sanitary drainage system. Note: A macerating system may comprise three major components: the container that houses the operating mechanisms, the…

This International Standard specifies mechanical safety requirements and test methods applicable to walk-behind powered edgers that employ rigid cutting means with a blade tip circle not more than 305 mm in diameter, and where the plane of the blade tip circle is designed to operate at not more than 15° from the vertical. This International Standard applies to hand-held portable and powered…
