Product Summary:

RT-404B Digital Fiber Film Paper Tearing Strength Test Machine is suitable for testing the tear strength of a certain number of pre-cuts in paper materials, in line with ISO1974 “Paper – Determination of Tear Strength (Erimendorph Method)” and GB455.1 “Paper Tear Strength Tester.”

It is applicable to determining the tearing degree of various types of paper and can also test the tear resistance of sheet composite materials such as low-strength cardboard, textiles, leather, and films.

a) Paper: tearing is suitable for the tearing strength test of base paper, printing paper, bobbin paper and other materials

b) Fiber material: tear is suitable for the tear strength test of glass fiber, carbon fiber and other materials

c) Film: tear strength test of tearing optical film, composite film, superconducting film, insulating diaphragm material

d) Other materials: tearing is suitable for tearing strength testing of non-woven fabrics, fabrics, leather, and other composite materials

Test principle:

The equipment has a stack of samples (usually 4 layers) with prescribed pre-cuts. The pendulum is lifted to a certain height to make it have a certain potential energy. When the pendulum swings freely, it uses its own stored energy to tear the sample to a fixed distance. The potential energy loss of the pendulum measures the work done in tearing the specimen.

According to the standard:

GB/T 455, QB/T 1050, GB/T 16578.2, ISO 1974, TAPPI T414 and other test standards
