Dried milk — Determination of titratable acidity (Reference method)
Applies to all types of dried milk. The principle constitutes in preparing reconstituted milk by adding water to a test portion of dried milk. The reconstituted milk is then titrated with sodium hydroxide solution to the pH of 8,40. The number of millimetres used in the titration is multiplied by the factor 2 in order to obtain the number of millimetres required to titrate a quantity of milk…
The purpose is to establish certain basic requirements for the marking of steam traps, and to give recommendations for additional information markings. Has, in general, to be considered in conjunction with the specific requirements which may be agreed between the partners concerned. Specifies mandatory and optional markings for steam traps.
Shipbuilding — Deck machinery — Warping end profiles
Specifies the types, nominal sizes, dimensions and designation of warping end profiles mounted on extensions of vertical or horizontal shafts and intended for windlasses, capstans, mooring winches and various shipboard winches including winches used for fishery and for hauling in steel wire rope and ropes of natural and man-made fibre.
Steel and cast iron — Determination of sulfur content — Gravimetric method
The method is applicable to products having sulphur contents greater than 0,003 % (m/m). It is particularly suitable as a reference method for the standardization of samples on which certified standard values are to be established. Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
Laboratory sintered (fritted) filters — Porosity grading, classification and designation
Filters are graded according to their pore size index in one of the eight classes specified. This is applicable to laboratory filters made of glass, vitreous silica, ceramics, metals and plastic materials. Annex A specifies a method for determination of pore size index. Annex B and C concern with a procedure for assessing uniformity of filters and for determination of air permeability.

Applicable to products having contents, expressed as sulphate2- , between 0.03 % (m/m) and 0.5 % (m/m). Reduction of the compounds to hydrogen sulphide by heating with a mixture of hydriodic and hypophosphorus acids in the presence of hydrochloric acid. Entrainment of the hydrogen sulphide in a flow of nitrogen and absorption in an excess of ammoniacal cadmium acetate solution. Liberation of the…
The requirements specify a basic series of liquid-in-glass solid-stem thermometers not exceeding 375 mm in length for accurate measurement of temperature. Temperature scale, materials and construction, marking, and accuracy are described. The annex deals with a method of determing change in zero indication.
