This International Standard specifies a method of determining the viscosity of industrial cellulose nitrate, usually referred to as nitrocellulose, the nitrogen content of which can vary between 10,7 % by mass and 12,6 % by mass, depending on the type. It also gives a classification system for industrial cellulose nitrate solutions (see annex A) which is based on viscosity measurements made using…

This International Standard specifies the characteristics of a case for use with 120 mm DVD-RAM disks as specified in ISO/IEC 16824. This International Standard specifies three related, but different implementations of such cases, viz. Type 1 Provides a case for a one-sided (Type 1S) or a two-sided (Type 2S) DVD-RAM disk such that the disk can not be removed from the case. This case is reversible…

1. Scope 1.1 This Standard covers the design, construction, operation, and maintenance of oil and gas industry pipeline systems that convey (a) liquid hydrocarbons, including crude oil, multiphase fluids, condensate, liquid petroleum products, natural gas liquids, and liquefied petroleum gas; (b) oilfield water; (c) oilfield steam; (d) carbon dioxide used in oilfield enhanced…

1 General The purpose of this standard is to harmonize as far as practicable all rules and requirements of a general nature applicable to low-voltage switchgear and controlgear in order to obtain uniformity of requirements and tests throughout the corresponding range of equipment and to avoid the need for testing to different standards. All those parts of the various equipment standards…

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…

2 Scope 2.1 Type of equipment This Standard applies to cast resin partitions pressurized with inert gases, eg, sulphur hexafluoride, carbon tetrafluoride, or a mixture of such gases, such as sulphur hexafluoride and nitrogen used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric and/or arc-quenching…

In general, this standard applies to the safety of automatic electrical controls, including controls using NTC or PTC thermistors, for use in, on, or in association with equipment for household and similar use, including controls for heating, air-conditioning and similar applications. The equipment may use electricity, gas, oil, solid fuel, solar thermal energy, etc., or a combination thereof.…
