Waterproof breathable fabric test methods

In the fabric show, often encounter such customers, need waterproof and breathable up to 10000/10000 composite fabrics. Then how to explain the customer will ask for such a high index? One possibility is that customers do not understand this line, see Gore's clothes marked 10000/10000, we must do such a high indicator; there is a possibility, that is, laymen Some people often do not understand and use, that is, different test methods.
What is the current test method?
1, control the cup method
1.1 water vapor transmission method
1.1.1 is the cup method
A, China National Standard: GB / T12704-91 B
B, American Society for Testing Materials Standard: ASTM E96 Produce B and D
C, Japanese Industrial Standards: JIS L-1099 A2
D, Canadian Standard: (CGSB) -4.2 No.49-99
E, British Standard: BS 7209-1990
1.1.2 pour cup method (also called hygroscopic method)
A, American Society for Testing Materials Standard: ASTM E96 BW (1995 edition and 2000 edition)
1.2 desiccant method
1.2.1 is the cup method
A, China National Standard: GB / T 12704-91 A.
B, Japanese Industrial Standard: JIS L-1099 A1
C, American Society for Testing and Materials Standard: ASTM E-96 A, C, E.
1.2.2 pour cup method
A, Japanese Industrial Standards: JIS L-1099 B1, B2
B, American Society for Testing and Materials Standard: ASTM E-96
C, Belgium UCB standard: UCB method
D, British Standard: B.T.T.G method
2, sweating hot plate method, also known as skin model method
A, ISO standard: ISO 11092
B, fire protective clothing test: NFPA 1971
C, American Society for Testing and Materials Standard: ASTM F 1868-98 B.
D, German standard: DIN 54 010 T01-A
3, sweating dummy method
The dummy of the sweaty dummy is a bit like a hot plate, used to simulate the shape and size of a typical human body. Dummy testing is more practical than sweating hot plate testing because it allows for more variables to be considered, including the surface area over which the garment covers the human body, the number of layers of fabric and the air layer on the surface of the body, loose or tight fit, different parts of the human body Skin temperature differences, body position and movement status and so on. However, no sweat dummy has yet been able to test evaporative heat resistance under dynamic conditions such as walking.
Currently, there is no sweat dummy design standards and test steps. And because the sweat dummies are more complicated and costly, the dummy test cost is higher than the hot plate method.
