Textiles — Determination of the aerobic biodegradation of textile materials in seawater
Scope:
This document specifies a laboratory test method for the determination of the aerobic biodegradability of textile materials in seawater by measuring the biochemical oxygen demand (BOD) or the amount of evolved carbon dioxide.
This method involves a test under an aerobic condition, which is intended to replicate the sea surface area conditions. It applies to textile materials, such as staple fibres, tops, yarns and fabrics. This test method is not intended for evaluating anaerobic biodegradation of textile materials, as simulating deep sea environments is out of the scope of this document.

Plastics — Conducting materials — Eddy current measurement on spread carbon fibre tow
Scope:
This test method defines test terms and specifies a standard method for evaluating the homogeneity of electrically conductive spread carbon fibre tow using eddy current measurement. The impedance in the width direction of the fibre is measured continuously, and the standard deviation of the measured impedance determines the homogeneity of the conductive material in fibre form.

Textiles - Oil repellency - Hydrocarbon resistance test (ISO/FDIS 14419:2026)
Scope:
This document specifies a method for the evaluation of a substrate's resistance to absorption of a selected series of liquid hydrocarbons of different surface tensions.
This document provides guidance to oil stain resistance. It can provide a rough index of oil stain resistance as, generally, the higher the oil repellency grade, the better resistance to staining by oily materials, especially liquid oil substances. This is particularly true when comparing various finishes for a given substrate. This document can also be used to determine if washing and/or drycleaning treatments have any adverse effect on the oil repellency characteristics of a substrate.
NOTE 1 Washing and drycleaning treatment procedures are described in ISO 6330 and ISO 3175 (all parts), respectively.
This document is not intended to give an absolute measure of the resistance of the substrate to staining by all oily materials. Other factors, such as composition and viscosity of the oily substances, substrate construction, fibre type, dyes and other finishing agents, also influence stain resistance. This document is not intended to estimate the resistance to penetration of the substrate by oil-based chemicals.
NOTE 2 For the evaluation of the resistance to penetration of the substrate by oil-based chemicals, see ISO 6530.
