SGS-IPS Testing performs a variety of NonWovens Standard Procedures (NWSTs were formerly called WSP test methods) at its Northeast Wisconsin testing laboratory. These test methods are the harmonized results of INDA’s and EDANA’s efforts to develop worldwide test methods for the global nonwovens industry.
