En388 protective glove performance tester

En388 protective glove performance tester includes Martindale wear tester, glove cutting resistance index tester, glove tear resistance tester, glove puncture resistance tester, etc

the principle of Martindale wear tester is that under the specified pressure, the circular specimen carries out circular plane motion friction with Lissajous figure, which is the motion track of simple harmonic vibration with two vibration directions perpendicular to each other and frequency in a simple integer ratio. The friction resistance is characterized by the cycle of the sample when it is damaged. Breakage refers to the hole through which the test sample has penetrated

the Martindale wear tester described in eniso12947-1 is adopted. The total mass of the loading block and sample holder assembly shall be (595 ± 7) G, so as to ensure that the sample can withstand (9 ± 2) kPa

the glove cutting resistance index tester cuts the sample back and forth by a circular blade moving back and forth under a fixed load until it is cut through; This test does not apply to gloves made of very hard materials, such as metal chain ring gloves

on the blade of the glove cutting resistance index tester, apply (5 ± 05) n pressure; The maximum cutting speed of the blade is 10 cm / s

the tear resistance tester is used to test the force required to tear a rectangular specimen with half opening along the length direction; The instrument must be a low inertial force measurement system. Tear resistance tester in (100 ± 10) The tearing force was recorded at the tensile speed of 10 mm / min

the tear resistance of each sample is the highest value recorded, while the tear resistance grade of gloves is determined by the lowest value of the four test results. The specimen shall be completely torn apart. 1f the specimen has not been completely torn off under the action of more than 75n force, the test can be stopped and the maximum force reached can be recorded

the glove puncture resistance tester is the force required to pierce the fixed test sample with a certain size of steel needle. 1t’s different from puncturing with a small needle or other sharp object. The glove puncture resistance tester should be able to measure 0 ~ 500N force; 1t must be low inertia compression; The test needle must meet the standard requirements

the glove puncture resistance tester moves the steel needle downward to the test sample at the speed of 100 mm / min until the displacement relative to the sample reaches 50 mm. Record the maximum value of this force, even if the sample has not been penetrated at this time
