ISO 1798 Testing (Tensile Strength & Elongation) for Flexible Polymeric Foams
ISO 1798 is the test method for the tensile strength and elongation at break of flexible cellular materials (flexible foams). To match this to your program, talk with our team.
What ISO 1798 Covers
It measures how far a flexible foam stretches and the force it carries before breaking, key properties for cushioning, seating, and packaging foams.
How the Test Is Run
A foam specimen is pulled in tension at a controlled rate until it breaks, and tensile strength and elongation at break are determined from the load-extension data.
Why It Matters
Tensile strength and elongation characterize flexible foam durability; grips and travel suited to soft, high-elongation material are needed.
