NWSP Nonwoven Fabric Tests

The NWSP Nonwovens Standard Procedures provide methods for testing the structure and performance of nonwovens and related materials, many of which have been developed by industry and adopted by ISO or CEN. EUROLAB Laboratory provides testing and evaluation services within the scope of NWSP standards.

Developed in partnership with INDA and EDANA, this resource helps to define the technical nonwovens industry with determinants for the properties, composition and specifications of its products. NWSP offers a cohesive language for the industry in the US and Europe and is recognized by many other individual markets, while the procedures provide a way for the nonwovens industry to communicate to ensure product specifications can change, both worldwide and within the supply chain. must be consistently defined, manufactured, and tested.
