This International Standard provides guidance for the content and drafting of a technical specification in order to ensure that all technical requirements of a product, process or service are included and can be verified as complying with specified performance requirements, such as may be specified in a functional specification (see ISO 13879). A technical specification may not be necessary for a…

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…

This International Standard specifies a method for the determination of the fat content of animal feeding stuffs. The method is applicable to animal feeding stuffs except oilseeds and oilseed residues. For the purposes of this method, the following two categories of animal feeding stuffs are distinguished. Samples of products in category B need a hydrolysis step prior to extraction. Category B…

This International Standard specifies a method for the determination of the moisture and other volatile matter content of animal feeding stuffs. The method is applicable to animal feeding stuffs with the exception of: a) milk products; b) mineral substances; c) mixtures containing a considerable amount of milk products or mineral substances, for example milk replacers; d) animal feeding stuffs…

This International Standard specifies a method for the determination of the particulate content of middle distillate fuels with a closed flash point of 38 °C or higher, determined in accordance with ISO 2719, ISO 3679 or ISO 13736. It is not applicable to light distillate fuels (gasolines) or to aviation fuels. A gravimetric limitation of the contamination of middle distillate fuels used in…

This International Standard specifies requirements and test methods for evaluation of the permanence and durability of writing, printing and copying on paper stored in libraries, archives and other protected environments for long periods of time. It is applicable to images on paper with the exception of documents within the scope of ISO/TC 42, Photography; multicoloured images. The…

This International Standard specifies a method for the determination of crude fibre content in tea.

This International Standard specifies methods for determining the thickness, bulk density, resilience, permanent linear change on heating, thermal conductivity, tensile strength and shot content of ceramic fibre products. It applies to ceramic fibre bulk, blankets, felts, mats, boards, papers and pre-formed shapes with the exception of products delivered in a wet state. The application of the…

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 a high-performance liquid chromatographic (HPLC) method for the determination of the furazolidone content of premixtures and animal feeding stuffs. The method is applicable to animal feeding stuffs with a furazolidone content of 25 mg/kg to 5 000 mg/kg and to premixtures with a mass fraction of furazolidone of up to 20 % [formerly written as 20 % (m/m)]. NOTE…
