DESCRIPTION

BS EN 4426:2020


This standard BS EN 4426:2020 Aerospace series. Non-metallic materials. Textiles. Test method. Determination of conductivity and pH of aqueous extracts is classified in these ICS categories:
  • 49.025.60 Textiles

This document specifies the requirements for the determination of conductivity and pH of aqueous extracts of textile materials.

This method has been written in response to an aerospace requirement for a method of extraction using hot water as the EN 1413 requires only a cold water extraction method.
