INDA Quality Standards

What Is INDA IST 90.3?

INDA IST 90.3, now globally recognized as NWSP 90.3, refers to the Handle-O-Meter Stiffness of Nonwoven Fabrics test. This method evaluates the “hand” of nonwoven materials, which is the combination of resistance from surface friction and flexural rigidity. It’s a critical test that measures the softness or stiffness of the material, which is essential for quality control and performance benchmarking.

Key Benefits of Testing to Meet INDA IST 90.3

• Ensures quality of nonwoven fabrics.
• Facilitates performance benchmarking for materials.
• Helps in substantiating company claims about product quality.
• Builds end-user confidence in the products.
• Supports regulatory compliance with industry standards.

INDA IST 90.3 Test Method

The Thwing-Albert Handle-O-Meter is an advanced instrument used to measure the stiffness or softness of nonwoven materials. Originally designed for nonwovens, this machine also provides valuable metrics for other sheeted materials, including tissue, toweling, plastic film, and textiles. The standard test procedure involves passing material through a restricted slot using a blade, which quantifies the stiffness or softness of the material.
