1. SCOPE 1.1 This standard contains requirements for the design, manufacturing and marking for three types of means of containment used for the transportation of Class 6.2 dangerous goods (infectious substances), diagnostic specimens, biological products and biomedical waste. - Type 1A (high integrity) - Type 1B (routine) - Type 1C (waste). 1.2 This…

This International Standard specifies the mechanical, physical and optical characteristics of a 120 mm optical disk to enable interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase…

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 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…
