【Test Principle】
After spraying (spraying method) or splashing (spraying method) the test solution on the chemical protective clothing worn on the test model or human test subject at a specified pressure and flow rate, check the inner surface of the chemical protective clothing and The surface of the water absorption indicator suit worn by the test model or human test subject is compared with the standard stain area to determine the liquid tightness of the chemical protective suit.
