Liquid chemical products — Measurement of colour in Hazen units (platinum-cobalt scale)
Applicable only to clear, slightly coloured liqids. Such colour characteristics are described as brownish-yellow. The principle is based on a visual comparison of the colour of a sample with that of colour standards. The results are expressed in terms of the platinum-cobalt scale. For routine control purposes a comparator, colorimeter or spectrophotometer may be used, if the values so obtained…

The conditions of temperature and relative humidity for pre-conditioning, conditioning, and testing of textile materials of all kinds and in all forms are specified. A standard temperate atmosphere, a standard temperate atmosphere for testing, a standard tropical atmosphere, and a standard tropical atmosphere for testing are defined. (The adjectives "temperate" and "tropical"…
Copper and copper alloys — Determination of manganese — Spectrophotometric method
The method is applicable to copper and all copper alloys, bronzes, brasses, copper-nickels and copper-aluminiums having manganese contents equal to or less than 6 %, which can be attacked under the conditions given in this International Standard. ISO 2543 specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report.
Defines terms relating to ropes and cordage. These terms are, in particular, for use in the drafting of other International Standards dealing with specification or testing of ropes. General terminology for the textile industry and terms defining specific ropes for the fishing industry, for agriculture, for marine use, etc. are not covered by this document. - Replaces ISO Recommendation R 1968-…
