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…
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…
