Agents de surface — Poudres à laver — Détermination de la masse volumique apparente — Méthode par pe...
La présente Norme internationale spécifie une méthode de détermination de la masse volumique des poudres à laver par pesée d'un volume donné.
La méthode est applicable aux poudres s'écoulant facilement et, à condition d'utiliser un entonnoir approprié, aux poudres légèrement collantes. Cette méthode est applicable à toute autre substance sous forme de poudre ou granulés. Dans le…
Pressure vessel steels not included in ISO 2604, Parts 1 to 6 — Derivation of long-time stress ruptu...
Defines a procedure for obtaining and for assessing the data necessary to establish long-time stress rupture values for steels for pressure purposes for steels where properties different from those internationally agreed are being claimed. The purpose of a standard procedure is to minimize any differences in long-time estimates obtained in different countries due to differences in the quantity…
Shipbuilding — Inland navigation — Coupling winches for push tows — Main dimensions
Specifies the dimensions and requirements necessary to allow the interchangeability. Does not specify the types of vessels on which the coupling winches may be installed; the decision being left to the shipowner.
Road vehicles — Motorcycles — Symbols for controls, indicators and telltales
Specifies the symbols, i. e. conventional signs, used to identify certain controls, indicators and tell-tales on a motorcycle and to facilitate their usage. Indicates the colours of possible optical tell-tales which warn the driver of the operation or malfunctioning of the devices and equipment connected to the corresponding controls.
Manganese ores and concentrates — Determination of potassium and sodium content — Flame atomic emiss...
The method is applicable to a concentration range of 0,08 to 3 % (m/m) of potassium and 0,02 to 1 % (m/m) of sodium. ISO 4571 should be read in conjunction with ISO 4297. Specifies principle, reagents, apparatus, procedure and expression of results.
Polypropylene (PP) pipes and fittings — Density — Determination and specification
The density shall be determined according the method described in ISO 1183 with an accuracy of 0,001 gram per cubic centimetre. The density shall be between 0,90 and 0,95 gram per cubic centimetre. This does not apply to pipes and fittings from PP-materials containing fibres or fire retardant additives.
