Acetone for industrial use — Methods of test — Part 4: Determination of permanganate time
The principle of the procedure consists in addition to a test portion, under specified conditions, of potassium permanganate solution. Determination of the time taken for the colour of this test solution to match that of a cobalt(II) chloride and uranyl nitrate colour standard. This document should be read in conjenction with ISO 757/1.
Industrial plate screens — Codification for designating perforations
The perforation of a plate is designated by 1: shape of the holes, 2. aperture size, 3. mutual arrangement of holes, 4. pitch, 5. orientation of the arrangement of the perforations relative to the edges of the plate. The code expresses the items of designation by symbols and magnitudes in the sequence above. The standard applies to perforated plates regardless of the plate material.
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).
