Earth-moving machinery — Operation and maintenance — Format and content of manuals
Establishes guidelines on the general rules necessary for the preparation and preservation of manuals for earth-moving machinery. A manual shall be simple to understand and have adequate explanatory notes, incorporate the use of internationally recognized symbols, and be easy to use and compact.
Specification for solventless polymerisable resinous compounds used for electrical insulation - Part...
Gives methods for tests for thermosetting coating powders as defined in Sub-clause 3.7 of IEC 60455-1. These tests are for material before cure and in cured form. The contents of the corrigendum of August 1991 have been included in this copy.
Specification for solventless polymerisable resinous compounds used for electrical insulation. Part ...
Contains the requirements for unfilled polyurethane resinous compounds in the cured form for classes PUR-U-4 to PUR-U-8 with an ash content of not more than 6%.
Manganese ores — Sampling — Part 2: Preparation of samples
Specifies methods of preparing samples of manganese ores for determining the chemical composition and moisture content of a consignment. The methods are applicable to natural or processed manganese ores. Details of the riffle divider to be used are given in the annex.
Fertilizers — Determination of ammoniacal nitrogen content in the presence of other substances which...
The method consists in entraining, by means of a strong current of air, of the ammonia from a moderately alkaline test mixture at ambient temperature into standard volumetric sulfuric acid solution, and back-titrating of the excess sulfuric acid solution with standard volumetric sodium hydroxide solution.
Phthalic and adipic esters for industrial use — Determination of free alcohols content — Spectrometr...
The free alcohol is reacted with vanadium(V) sodium salt of quinolin-8-ol(8-hydroxyquinoline) to form a coloured complex. The complex is extracted with toluene and then treated with dichloroacetic acid. The spectrometric measurement is carried out at a wavelength of about 620 nm. The method is applicable to products having free alcohol contents between 0,01 and 5,0 % (m/m).
Tool steels and bearing steels — Micrographic method for assessing the distribution of carbides usin...
Specifies a method for assessing steels with C levels between 0,1 % and 1,5 % and a total content of alloy elements less than or equal to 5 %. The use of this method for other steels shall be subject to special agreement. Contains principles, sampling, preparation of samples, assessment of the distribution of carbides, expression of results and test report. An annex gives reference…
