ISO 10465-3:2007 gives supplementary information on parameters and application limits for the underground installation of flexible glass-reinforced pipes based on unsaturated polyester resin (GRP-UP). It is particularly relevant when using an ATV-A 127 type design system. Explanations for the long-term safety factors incorporated into the GRP system standards based on simplified probabilistic…

This standard covers the connection assembly of fluid-filled and extruded cables to gas-insulated metal enclosed switchgear (GIS), in single- or three-phase arrangements where the cable-terminations are fluid-filled or dry type and there is a separating insulating barrier between the cable insulation and the gas insulation of the switchgear.

ISO 3994:2007 specifies the requirements for three types of helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of water, weak aqueous chemical solutions and abrasive solids and slurries, for use in the ambient temperature range from -10 °C to +55 °C. The three types of hose are for light-, medium- and heavy-duty applications. The types of hoses covered in the standard…

1 Scope 1.1 This standard applies to pin and sleeve type plugs, receptacles, power inlets, and connectors, rated up to 800 amperes and up to 600 volts ac or dc, and which may include two or fewer pilot contacts. These devices are intended to provide power from branch circuits, or are for direct connection to the branch circuit in accordance with the Canadian Electrical Code Part I (CEC), C22.1,…

1. SCOPE 1.1 This method of test for surface burning characteristics of building materials is applicable to any type of building material that, by its own structural qualities or the manner in which it is applied, is capable of supporting itself in position or may be supported in the test furnace as described in this standard or in a manner comparable to its recommended use. 1.2 The…

1. SCOPE 1.1 These requirements cover air filter units of both washable and throw-away types for removal of dust and other airborne particles from air circulated mechanically in equipment and systems.

L'ISO 10440-1:2007 spécifie les exigences relatives aux compresseurs rotatifs hélicoïdaux à lobes droits, à sec et plongés dans l'huile, utilisés dans les services d'industries du pétrole, de la pétrochimie et du gaz naturel pour créer des surpressions ou des dépressions ou les deux à la fois. Elle concerne les compresseurs à service spécial. Elle ne s'applique pas aux…

Applies to flexible cables with insulation based on ethylene propylene rubber (EPR), polyvinyl chloride (PVC) or silicone rubber (SiR) for portable earthing and short-circuiting equipment. For this type of cable no rated voltage is given as such cables are exclusively intended for earthing and short-circuiting equipment. The particular types of cable and their code designations are specified in…
