Technical data

Tear resistance test according to DIN ISO 34-1 Crescent for tear resistance measurements

The cutting die-unit „DIN ISO 34-1 Crescent“ consists of a cutting blade and spring-loaded down holders. The cutting- & nick-blade is made of powder-metallurgic knife steel and thereby guarantees an extreme lifetime.

Testing the tear resistance requires an exact nick at a defined point on the specimen. We offer a knife without, with fixed or variable scoring depth.

The blades are transversally sharpened on both sides, which results in vertical cut lines of an exact specimen cross section.
