摘要： ISO 21687:2007 specifies a method for the determination of the density of green and calcined petroleum coke and similar solid materials (e.g. electrodes). ISO 21687:2007 is also suitable for hydrocarbons with a high-temperature boiling range and for other solid *** method is not suitable for graphitized material.

摘要： This European Standard specifies a procedure for the determination of volatile isocyanates in the exhaust air of an emission test chamber after application of a low-solvent or solvent-free adhesive as defined in EN *** method is based on chemosorption of volatile isocyanates with 1-(2-methoxyphenyl) piperazine (in the following: 1-2MP) impregnated filters with subsequent desorption and liquid chromatographic analysis. The method permits measurement of a wide range of organic compounds containing isocyanate functional groups (NCO), including isocyanate monomers. For testing of adhesives emissions mainly toluene diisocyanate (TDI) and methylene bis (4-phenyl isocyanate also known as 4,4-diisocyanato-diphenylmethane or MDI), are of concern. The method as described in this European Standard can be used for other isocyanates too, such as isophorone diisocyanate (IPDI) and 1,6-hexamethylene diisocyanate (HDI) - see ISO 16702. Isocyanate oligomers or prepolymers are not volatile enough to be detected in emission test chambers at room temperature.

摘要： This International Standard specifies a method for the determination of the alkaline phosphatase activity in pasteurized whole milk, semi-skimmed milk, skimmed milk, cream and flavoured milks using a chemiluminescent (EPAS) method. The method is applicable to milk and milk-based drinks from cows, sheep, buffalo and goats. The method is also suitable for any liquid-based sample if diluted in such a way that the diluted alkaline phosphatase activity has less than 7 000 milliunits per litre. NOTE There has been a successful collaborative trial with cow, sheep, buffalo, and goat whole milk, as well as skimmed cow milk (< 0,5 % fat), 20 % fat cream and 2 % fat chocolate milk (all mass fractions).

摘要： This International Standard specifies the requirements and corresponding test methods for manufactured and natural micaceous iron oxide (MIO) pigments, in dry form, used primarily in protective coatings for steelwork. In accordance with current practice, the general requirements for micaceous iron oxide pigments have been sub-divided to give a) those requirements that are essential (see Table 2) and b) those requirements that are conditional upon prior agreement between the interested parties (see Table 3). In certain instances, reference may be made to an agreed reference pigment.

摘要： This International Standard specifies oil-sampling procedures, analysis requirements andprocedures, and recommends sensitivity, repeatability and accuracy criteria for the applicationof dissolved gas analysis (DGA) to factory testing of new power transformers, reactors andinstrument transformers filled with mineral insulating oil when DGA testing has been *** most effective and useful application of DGA techniques to factory testing is during theperformance of long-term tests, typically temperature-rise (heat run) and overloading tests onpower transformers and reactors, also impulse tests on instrument transformers. DGA mayalso be valuable for over-excitation tests run over an extended period of *** with DGA results, before and after short-time dielectric tests, indicates that DGAis normally less sensitive than electrical and acoustic methods for detecting partialdischarges. However, DGA will indicate when these partial discharges become harmful to theinsulation and may be detected by inspection [2].

摘要： This European Standard specifies a method for the determination of single volatile organic compounds (VOC)and of the total amount of volatile organic compounds (TVOCEN13999) in the exhaust air of an emission testchamber after application of a low-solvent or solvent-free adhesive as defined in EN 923. The method isbased on use of a solid sorbent with subsequent desorption and gas chromatographic analysis. The method isapplicable to measurement of non-polar and slightly polar VOC.
