Water quality — Determination of acute lethal toxicity to marine copepods (Copepoda, Crustacea)
This International Standard describes a method for the determination of the acute toxicity to one of three specified
species of marine copepod (Copepoda, Crustacea) of
a) chemical substances which are soluble, or can be maintained as a stable suspension or dispersion, under the
conditions of the test;
b) industrial or sewage effluents, treated or untreated, after decantation, filtration or…
Textiles — Determination of surface burning time of fabrics
The principle of the method is supporting a dry specimen of the fabric on a vertical plate, igniting its raised surface near the top in a specified manner, timing the spread of flame downwards on the surface of the fabric to a reference line. Applies to fabrics having a raised fibre surface, i.e. a napped, pile, tufted, flocked or similar surface.
Textile fabrics — Burning behaviour — Determination of ease of ignition of vertically oriented speci...
ISO 6940:2004 specifies a method for the measurement of ease of ignition of vertically oriented textile fabrics and industrial products in the form of single or multi-component fabrics (coated, quilted, multilayered, sandwich constructions, and similar combinations), when subjected to a small, defined flame. This method assesses the properties of textile fabrics in response to flame contact under…

ISO 6941:2003 specifies a method for the measurement of flame spread times of vertically oriented textile fabrics and industrial products in the form of single or multi-component fabrics (coated, quilted, multilayered, sandwich combinations, and similar combinations) when subjected to a small, defined flame.
Recycled carbon fibres — Designation system for recycled carbon fibres
1.1 This document establishes a designation system of recycled carbon fibres, which may be used as the basis for specification. 1.2 This designation system is applicable to recycled carbon fibres used in polymer composites. 1.3 The types of recycled carbon fibres are differentiated by a designation system based on appropriate levels of the designatory properties: a) tensile modulus of elasticity…
Smoke control door, shutter assemblies and self-closing glazed elements – Ambient- and medium-temper...
The test described in ISO 5925-1:2007 determines the rate of leakage of ambient (cold) and medium (warm) temperature smoke from one side of door and shutter assemblies to the other, under the specified test conditions. The test is applicable to door and shutter assemblies of different configurations intended for purposes of controlling the passage of smoke in case of fire.
The acceptable leakage…
