Textil- och läderteknik

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.

This document specifies a method for determining the stitch tear resistance of leather. It can be used on all leathers but is particularly suitable for leathers over 1,2 mm in thickness.

This document specifies a method, using acetone, to determine the percentage of acetate, after removal of non-fibrous matter, in textiles made of binary mixtures of

— acetate

with wool, animal hair, silk, regenerated protein, cotton (scoured, kiered, or bleached), flax (or linen), hemp, jute, abaca, alfa, coir, broom, ramie, cupro, viscose, modal, polyamide, polyester, acrylic, elastolefin, elastomultiester, melamine, polypropylene/polyamide bicomponent, polyacrylate and glass fibres.

It is not applicable to mixtures containing modacrylic fibres, nor to mixtures containing acetate fibres that have been deacetylated on the surface.

This document establishes a system of graphic symbols for use in the marking of the following floor coverings and specifies the use of these symbols:

— resilient floor coverings manufactured from plastics, linoleum, cork or rubber, excluding loose-laid mats;

— textile floor coverings, including loose-laid mats and rugs;

— laminate floor coverings;

— modular multilayer floor coverings.

This part of ISO 1833 specifies a method, using dichloromethane, to determine the percentage of triacetate or polylactide, after removal of non-fibrous matter, in textiles made of mixtures of

— triacetate or polylactide

with

— wool or other animal hair, silk, protein, cotton, viscose, cupro, modal,lyocell, polyamide, polyester, acrylic, elastomultiester, polypropylene, elastolefin, melamine, polypropylene/polyamide bicomponent,polyacrylate and glass fibres.

Triacetate fibres which have been partially hydrolysed (i.e. saponification) cease to be completely soluble in the reagent. In such cases, this method is not applicable.

This document specifies a method, using xylene, to determine the percentage of polypropylene, after removal of non-fibrous matter, in textiles made of binary mixtures of

— polypropylene fibres

with

— wool, animal hair, silk, cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, acrylic,glass fibres, elastomultiester, melamine and polyacrylate.

This guideline defines various preservation methods for raw hides. The preservation methods are needed to suppress microbiological activity and to maintain the quality and commercial value of the hides during storage.

This guideline applies to all raw hides of cattle and horses.
