Textil- och läderteknik

This part of ISO 1833 specifies a method, using sulfuric acid, to determine the mass percentage of silk, after removal of non-fibrous matter, in textiles made of binary mixtures of

— silk

with other protein fibres (e.g. wool or animal hair).

This part of ISO 18218 is a method for determining alkylphenols (nonylphenol and octylphenol) and alkylphenol ethoxylates (nonylphenol ethoxylate and octylphenol ethoxylate) in leather and process auxiliaries. The analysis is based on high-performance liquid chromatography (HPLC) or gas chromatography-mass spectrometry (GC-MS).

The analysis of the alkylphenol ethoxylate is made by cleaving the alkylphenol ethoxylate and measuring the released alkylphenol.

NOTE ISO 18218-1 and this part of ISO 18218 use different solvents for the extraction of the ethoxylated alkylphenols from leather. Consequently, the two analytical methods are expected to give similar trends but not necessarily the same absolute result for the ethoxylated alkylphenol content in leather.

This draft specifies requirements, methods of test and methods of sampling for full chrome upper leather. This draft is applicable for upper leather which is used in general sport footwear, school footwear, casual footwear, men’s town footwear, women’s town footwear, cold weather footwear, fashion footwear, infant footwear and indoor footwear.

1 Scope (mandatory)

This International standard provides recommendations for the installation and use of textile floor coverings on stairs for both residential/domestic and contract/commercial purposes. It covers all products composed of textile material with a pile or non-pile use surface including the use of such products in tile form.

NOTE In many split-level dwellings, a room may have one or two steps between different levels. This situation differs from a stairway in several important respects:

— the steps are usually wider and therefore traffic intensity in any one place is usually less;

— the carpet may be bent over steps in either the machine direction or the across-machine direction. On a stairway, it is normal practice to lay the carpet with the pile lying down the stairs.
