Linear cutting test (EN 388 cutting test)

Test principle: Fix the sample on the fixture, and use a rotating circular cutting blade to cut the material in a straight line back and forth under a constant pressure (usually 5N). Record the number of cycles required for the blade to cut through the material.

Grade determination: It is classified into grades 1 to 5 based on the number of cuts, with Grade 5 being the highest cutting resistance grade (cut times ≥2000).

Applicable scenarios: Flexible fabrics, cut-resistant glove fabrics, which can directly reflect the protective ability in daily cutting scenarios.

Dynamic cutting resistance test (ISO 13997 standard)

Test principle: Simulate the scene where a sharp object cuts through the material at high speed. Use a sharp rectangular blade to impact the sample at a fixed speed and Angle, and measure the impact force required to cut through the material.

Features: It is closer to the actual sudden cutting (such as the tool quickly sliding towards the hand), making up for the deficiencies of static cutting tests, and is often used for the detection of military and police protective equipment.

Tool puncture cutting test

Test principle: Fix the hard sample, and use a standard tool (such as a hard alloy tool) to puncture vertically downward under a constant load and slowly cut the material. Record the cutting depth or the force value required for complete cutting.

nti-riot shields, equipment protective baffles, wear-resistant pipes, etc., to assess the material's ability to resist continuous cutting by sharp tools.

Abrasive cutting wear test

the friction and cutting of sharp particles in industrial scenarios. Rub the sample against abrasive grains (such as quartz sand, metal debris) under a certain pressure, and test the weight loss rate or thickness wear of the sample after a certain period of time.

Applicable scenarios: Mine conveyor belts, wear-resistant liners, reflecting the durability of materials under the erosion and cutting of particles.
