ISO 7105:1985 工业用无水液氨 水含量的测定 卡尔·费休法

A test portion is evaporated in the presence of ethanediol and the water content of the residue is determined by the Karl Fischer method with direct electrometric measurement. The method is applicable to products having water contents equal to or greater than 50 mg/kg. For water contents greater than 1000 mg/kg it is preferable to dilute the evaporation residue with anhydrous methanol in accordance with ISO 4276 and titrate an aliquot portion of the diluted solution.

ISO 7106:1985 工业用无水液氨 油含量的测定 重量法和红外光谱法

A test portion is evaporated at ambient temperature and the oil contained in the residue is extracted with carbon tetrachloride. The oil contained in the residue is determined either gravimetrically by evaporation of the organic solvent and weighing of the residue or by spectrometric measurement of the absorbance of the organic phase at a wavelength of approximately 3.42 m. The gravimetric method is applicable to products having an oil content equal to or greater than 10 mg/kg. The infra-red spectrometric method, being more sensitive, is applicable to products having an oil content greater than 1 mg/kg.

BS 6075-12:1981 工业用氢氧化钠取样和试验方法.第12部分:铜含量测定

This Part of BS 6075 describes a method of test for the determination of the copper content of sodium hydroxide for industrial use. The method is applicable to products having copper contents, expressed as Cu, in the ranges 0.5 mg/kg to 10 mg/kg and 0.25 mg/kg to 5 mg/kg for the solid and liquid products, respectively. There is no corresponding international standard for this method.

BS 6075-1:1981 工业用氢氧化钠取样和测试方法 氢氧化钠含量的测定

This International Standard specifies a method of assay of sodium hydroxide for industrial use. This assay can be expressed conventionally, as percentages by mass of NaOH, in two different ways: A total alkalinity (NaOH equiv.); B caustic alkalinity (NaOH c.), corresponding to the total alkalinity less the alkalinity due to carbonates.

BS 6075-3:1981 工业用氢氧化钠取样和测试方法 铁含量的测定

This International Standard specifies a 1,10-phenanthroline photometric method for the determination of the iron content of sodium hydroxide for industrial use. This method is more sensitive and more widely used than the 2,2'-bipyridyl method which was specified in ISO/R 983-1969. The method is applicable to products having iron contents equal to or greater than 0,5 mg/kg.
