This document specifies the requirements for rubber hoses and rubber hose assemblies used for the transfer of liquefied petroleum gas (LPG) in liquid or gaseous phase and natural gas with a maximum working pressure of 25 bar (2,5 MPa) and vacuum within the temperature range of -30 °C to +70 °C and, when designated -LT, -50 °C to +70 °C.

 

This document specifies the design, materials, dimensions and marking requirements for cam locking couplings that serve as the link between hoses and connections to transport liquids, solids and gases, except liquid gas and steam. For all sizes of aluminium cast material couplings and for all couplings of size DN 100, the pressure range is from -0,8 bar to 10 bar in the working temperature range from -20 °C to +65 °C. All other couplings according to this document are capable of operating within the pressure range from 0,8 bar1 to 16 bar in the working temperature range from -20 °C to +65 °C.

 

This document specifies a method for the determination of the water vapour transmission rate (often erroneously called “permeability”) of sheet materials. This method is not generally recommended for use if the transmission rate is expected to be less than 1 g/m2 per day or for materials thicker than 3 mm. In such cases the method specified in ISO 9932 is preferred. The method cannot be applied to materials that change dimensionally (shrink or expand) to an appreciable extent under the test conditions used. In the case of materials that are damaged by hot wax, only mechanically-sealed test dishes can be used. For some purposes it may be necessary to determine the transmission rate of creased material; a procedure for this is given in Annex B.

 

 

This document defines terms, gives guidance for classification and establishes requirements for nucleic acid- and protein-based bio-devices. This document is applicable to bio-devices incorporating natural, modified and synthetically derived nucleic acid and/or protein. This document does not apply to medical devices or products.

 

This part of ISO 8502 describes a method of extracting and analysing of water-soluble contaminants from a surface by use of filter paper which can be attached to any surface, regardless of its shape (flat or curved) and its orientation (facing in any direction, including downwards). The method described is suitable for use in the field to determine the presence of water-soluble contaminants before painting or a similar treatment. NOTE The extraction method can give a false conductivity result or not take all the water-soluble material off the surface because of: (1) Soluble materials hiding in the crevices or under folds of metal; (2) Soluble materials under corrosion layers, passivation layers produced by corrosion inhibitors, oil, grease, or other non-visible thin films.

 

 

This document specifies requirements for utility lighters to ensure a reasonable degree of safety for normal use or reasonably foreseeable misuse of such lighters by users. This document applies to all flame-producing consumer products commonly known as utility lighters (also known as grill lighters, fireplace lighters, lighting rods or gas matches), and similar devices. It does not apply to matches and flame-producing products intended for igniting cigars, pipes and cigarettes.

 

This document specifies a method of determination of the sieve residue (gross particle and coagulum content) of polymer dispersions. This document is only applicable to coagulum type content.

 

This document specifies requirements for high chromium white cast iron grit, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements, metallographic structure and chemical composition. The requirements specified in this document apply to abrasives supplied in the new condition only. They do not apply to abrasives either during or after use. High chromium white cast iron grits are used in both static and site blasting equipment. They are most often selected where there is a possibility for the recovery and re-use of the abrasive. NOTE 1 Although this document has been developed for preparation of steelwork, these materials are predominantly used for non-ferrous substrates. The properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques, and can be used for applications where no subsequent coating is applied. NOTE 2 Whenever dissimilar metals are used together, galvanic corrosion can occur.

 

This document specifies requirements for lighters to ensure a reasonable degree of safety for normal use or reasonably foreseeable misuse of such lighters by users. This document applies to all flame-producing products commonly known as cigarette lighters, cigar lighters and pipe lighters. It does not apply to matches and flame-producing products intended solely for igniting materials other than cigarettes, cigars, and pipes.

 

This document specifies the principal specifications of the thermoplastic water meter cabinets in terms of  the thickness of material, design drawing, dimensions and accessories incorporated into the construction of it for pipe sizes from 1/2” to 1 1/4” (from 12,7mm to 31,75 mm).

 

This document specifies a method for the extraction of phosphorus soluble in mineral acids in inorganic fertilizers.

 

This document specifies a method for the extraction of the total sulfur contained in fertilizers in elemental form and/or in other chemical combinations. The method is applicable to inorganic fertilizers for which a declaration of the total sulfur present in various forms (elemental, thiosulfate, sulfite, sulfate) is provided.

 

This document specifies a method applicable to inorganic fertilizers for the extraction with diluted mineral acid of total calcium, total magnesium and total sodium and for the extraction of total sulfur present in the form of sulfates, so that the same extract may be used for the determination of each nutrient required.

 

This document specifies a method for the extraction of water-soluble calcium, magnesium, sodium and sulfur (in the form of sulfates), so that the same extract can be used for the determination of each nutrient required. This document is applicable to inorganic fertilizers.

 

This document lists the best available acute-toxicity data of gases taken from a search of the current literature to allow the classification of gases and gas mixtures for toxicity by inhalation.

 

This document specifies requirements of rubber hoses used in the automotive turbocharger system to connect turbocharger, intercooler, and internal combustion engine at the working temperatures from -40 °C to +250 °C and the working pressures from -0,01 MPa(-0,1 bar) to 0,5 MPa(5 bar). Hoses covered by this document are straight or shaped.
