Metallic powders, excluding powders for hardmetals — Determination of dimensional changes associated...
This second edition cancels and replaces the first edition (i. e. ISO 4492:1978). The method is applicable to the determination of three types of dimensional changes involved with the processing of metallic powders. Gives principle, test parameters, symbols and designations, apparatus, sampling, procedure, expression of results and test report. An annex contains information on demensional change…
Information processing - Reels for 12,7 mm (0,5 in) wide magnetic tapes - Sizes 16, 18 and 22

Liquefied anhydrous ammonia for industrial use — Determination of oil content — Gravimetric and infr...
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…
