ISO 9073-12描述了当一面接触液体且织物处于机械压力下时，评估织物吸收性的方法。 本试验旨在对非织物等吸收性材料进行比较，而不是模拟成品的使用条件。 需求吸收性也称为需求润湿性。

ISO 9073-12 describes a method for the evaluation of the absorbency of fabrics when one side is in contact with a liquid and the fabric is under mechanical pressure. This test is designed to allow comparison of absorbent materials such as nonwovens and is not intended to simulate in-use conditions of finished products. Demand absorbency is also called demand wettability.
