AATCC42 Waterproof Impact Penetration tester
Introduce:
This instrument is used to measure the seepage resistance of fabric under low impact conditions. It can be used to predict the seepage resistance of wear fabric. It is not suitable for fabrics that cannot be stretched flat under certain tension.

AATCC42 Waterproof Impact Penetration Tester
Three, principles and steps:
A certain amount of water is sprayed from a height of (610±10) mm from the sample to be tested onto the surface of a test specimen with a given weight of absorbent paper attached to the back of the test specimen.After spraying, weigh the absorbent paper again and calculate the permeability
One end of the sample is clamped on the steel plate with a metal spring clip along the width direction. The length of the metal spring clip is (152±10) mm, and then the other free end of the sample is clamped by the metal spring clip with the length of (152±10) mm and the total mass is (0.45±0.05) kg. The test surface of the sample is sprayed.Weigh the mass of white blotting paper of (152±10) mm× (229±10) mm, accurate to 0.1g, and insert it between the sample and the test stand.
Pour (500±10) mL of the reagent into the funnel of the tester and start spraying the sample. In the process of pouring water, vortex phenomenon should be avoided as far as possible.After the end of spraying (continuous spraying stop 2s), carefully remove the absorbent paper, and quickly weigh the mass of the absorbent paper, accurate to 0.1
