Warning - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions.
question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set by the relevant national regulations.
1 Scope
This standard specifies methods for testing the wicking properties of rubber or plastic coated fabrics.
This standard applies to single or double coated rubber or plastic coated fabrics.
This standard method A is applicable to the production of coated fabrics for non-liquid filled products, such as tarpaulins, advertising cloths, tarpaulins, booms, etc.;
B is suitable for the production of coated fabrics for liquid-filled products, such as soft storage and transportation oil (water) tanks, rubber dams, and the like.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Wicking wickingofthecloth
The movement of the liquid by the capillary action of the fibers along the walls of the coated fabric fibers.
3.2
Wicking height wickingheight
A measure of the capillary effect of a fiber reinforced layer, the height at which the liquid moves freely upward along the fiber reinforced layer over time.
3.3
Wicking speed wickingrate
The distance the liquid moves along the fiber reinforced layer per unit time at a set pressure.
4 Principle
One end of the coated fabric sample is immersed in the dyeing solution, and the fiber reinforced layer is dyed by wicking, and is dyed according to the fiber reinforced layer for a certain period of time.
The length determines the wicking properties of the coated fabric.
5 test conditions
5.1 Test liquid
The liquid specified in the product specification, or the use of three grades of water in accordance with GB/T 6682, for easy observation and measurement, can be added in the third grade water
