ASTM D 5035 Tensile - Describes raveled strip and cut strip test procedures for determining the breaking force and elongation of most textile fabrics. Testing Services for the paper, nonwovens, packaging, and consumer products industries.
The ASTM D3786 Bursting Strength test method describes the measurement of the resistance of textile fabrics to bursting using a hydraulic or pneumatic diaphragm bursting tester.
ASTM D 3776 covers the measurement of fabric mass per unit area (weight) and is applicable to most fabrics. The method describes four approved options for use in the measurement of basis weight. Option A – Full Piece, Roll, Bolt or Cut (Section 7). Option B – Full Width Sample (Section 8).
From Stiffness, Abrasion Resistance and Air Permeability to Barrier Properties, Water Vapor Transmission and Flammability, we utilize various test methods to tell you how your materials stack up against your objectives and your competitors. For nonwovens testing, we perform AATCC, ASTM, CFR, ISO, TAPPI, WSP and our own IPS test methods.
