Water Impact Penetration Test machine Waterproof performance test

MODEL: SM4418A

Water Impact Penetration Tester is used to determine the water resistance of fabrics under low impact conditions, and to predict the rain resistance of wearing fabrics.

Spray a certain amount of water from a height of (610±10) mm from the sample to be tested to the suSMace of the sample with a certain tension, and attach a known weight of absorbent paper on the back of the sample. After spraying, weigh the mass of absorbent paper again and calculate the permeability.

One end of the specimen is clamped on the steel plate with the metal spring clamp along the width direction. The length of the metal spring clamp mouth is (152 ± 10) mm, and the total mass is (152 ± 10) mm( zero point four five + zero point zero five )Kg metal spring clamps the other free end of the sample, and the test suSMace of the sample is subject to spray. Weigh the mass of white absorbent paper (152 ± 10) mm × (229 ± 10) mm to the nearest 0.1g And insert it between the sample and the test bench.

Pour (500 ± 10) ml of reagent into the funnel of the tester to spray the sample, and avoid vortex as much as possible during water pouring.

After the completion of spraying (2S after the continuous spraying stops), take out the absorbent paper carefully, and quickly weigh the mass of the absorbent paper to the nearest 0.1g
