Test Methods

Logo NWSP final


In 2005, EDANA and INDA, the leading global nonwovens associations, started to jointly publish the standard procedures for the nonwovens and related industries.

These Nonwovens Standard Procedures offer methods to test the structure and performance of nonwovens and related materials, many of which have been developed by the industry, and adopted by ISO or CEN.

Every 3 years a new updated version was released. In 2018 it was decided to change this periodic review into a continuous review. This allows amendments to be published directly instead of waiting till the next release. This of course is only possible through on-line publishing. As a consequence, we don’t publish a complete compilation of all methods in a single file anymore.

How to access the test methods?

Members can access all actual procedures -free of charge- on the EDANA member portal: in the Document module, type “actualNWSPs” in the search bar and all methods will appear as well as the Table of Content (that includes hyperlinks to directly pre-view the individual methods).

Non-members are invited to visit our product dedicated webpage or contact Marie-Josepha Peeters to purchase the complete compilation or one or more individual methods.

For information about the methods that are available, please download the table of contents.
