The designations of metals and alloys shall be based on the chemical composition limits given in International Standards. International chemical symbols shall be used for the designation of the principal metal and the major alloying elements followed by numbers indicating the metal grade or the nominal alloy content.

Specifies a method to determiine if a flammable material, when maintained at a selected equilibrium temperature and under the conditions of the test, gives off sufficient flammable vapour at this temperature to cause ignition on application of an external source of flame applied in a standard manner. The method is suitable for use over the temperature range 5 to 65 C.

The Standard specifies the following characteristics of the oil: appearance, colour, odour, relative density at 20/20 °C, refractive index at 20 °C, optical rotation at 20 °C, miscibility with 70 % (V/V) ethanol at 20 °C, ester value after acetylation, carbonyl value. Most of the characteristics differ in dependence from the country of origin.

The Standard specifies the following characteristics of the oil. Appearance: Clear, mobile liquid. Colour: Almost colourless to pale yellow. Odour: Characteristic, spicy, sweet. Relative density at 20/20 C: 0,883 - 0,934 1) 0,857 - 0,880 2). Refractive index at 20 °C: 1,4740 - 1,4880 1) 1,4690 - 1,4800 2). Optical rotation at 20 °C: + 2 - + 30 1) + 20 - + 45 2). Miscibility with 90 % (V/V)…

Basis for this method is the laboratory sample obtained by the method specified in ISO 948. The principle of determination consists in grinding the laboratory sample, which has been previously mixed, to obtain particles of the size specified in the International Standard appropriate to the spice or condiment concerned or, if not so specified, to obtain particles of size approximately 1 mm.

Scope 1.1 This Standard applies to mechanical flue-gas exhausters intended to be installed in a flue pipe, breeching, or chimney and serving appliances burning natural gas, propane, or fuel oil. 1.2 This Standard covers the mechanical and electrical features of mechanical flue-gas exhausters for indoor or outdoor installations. 1.3 This Standard classifies mechanical flue-gas…

1. Scope 1.1 This Standard applies to the provision of alternative combustion heads or end-cones intended to be fitted to currently in-service residential gun-type burners for the purpose of improving combustion efficiency. 1.2 This Standard also applies to the provision of complete residential gun-type burners intended for the purpose of improving combustion efficiency.

1. Scope 1.1 This Standard applies to the continuous measurement of ozone in air. 1.2 This Standard sets forth the chemiluminescence method for the measurement of concentrations of ozone between 2 µg·m-3 and 10 mg·m-3 at 25°C and 101.3 kPa (approximately 0.001 ppm v/v and 5 ppm v/v). Notes: (1) All concentrations referred to throughout this Standard are based on a temperature…
