The Standard specifies the following characteristics of the oil. Appearance: Clear, mobile liquid. Colour: Almost colourless to bluish-green. Odour: Characteristic, recalling that of whole pepper. Relative density at 20/20 °C: 0,870 - 0,890. Refractive index at 20 °C: 1,4800 - 1,4920. Optical rotation at 20 °C: Range from - 16 to + 4 . Miscibility with 95 % (V/V) ethanol at 20 °C: 1 : 3.

Only leak detectors are described which have an integral high vacuum system to maintain the sensing element of the mass spectrometer at a low pressure. Two procedures are outlined, one to determine the minimum detectable leak rate and the other for determination of the minimum detectable concentration ratio.
Specifies the recommended procedure for the installation of asbestos-cement pipelines for both pressure and non-pressure installations. Covers the types of laying conditions most commonly encountered in practice. Describes handling and storage, stringing out, lowering, laying, jointing and anchorages of the pipes as well as excavation and preparation of the trench and house service connections.
