Acetic anhydride for industrial use — Methods of test
Gives general instructions and specifies methods of analysis. The methods to be used are determination of destillation yield, of bromine number, of arsenic content, of permanganate index, of dichromate index, the measurement of colour, titrimetric determination of acetic anhydride content, gravimetric determination of ash, spectrometric determination of phosphate content and visual limit tests…
Phenol, o-cresol, m-cresol, p-cresol, cresylic acid and xylenols for industrial use — Methods of tes...
This method is applicable to products having a dry residue after evaporation, greater than or equal to 0,005 % (m/m). The principleconsists in evaporation of a test portion in a platinum dish on a boiling water bath and drying of the residue in an oven at (105 +- 2) °C for 1 h. Replaces ISO Recommendation R 1900-1971.
Power sources for manual metal arc welding with covered electrodes and for the TIG process
Specifies the information to appear on the rating plate and describes test methods to verify the compliance of the power source with this International Standard. Applies to the types of power sources most commonly used in industrial applications for manual metal arc welding with covered electrodes and for the TIG process, except for oil-cooled power sources.
Caprolactam for industrial use — Determination of absorbance at a wavelength of 290 nm
The spectrometric measurement of the absorbance of a 50 % caprolactam water solution is carried out at a wavelength of 290 nm. The absorbance, expressed in relation to an optical path length of 1 m, is given by a specified formula in which AO is the correction for the difference in absorbances of the cells; A1 is the absorbance of the test solution, and 1 is the optical path length, in…
