Abstract
A method of measuring the liquid retention of absorbent articles (20) of the kind that includes an absorbent body having a top side which lies proximal to the wearer's skin when the article is worn, and a bottom side which is covered by a liquid-impermeable backing sheet, wherein the method comprises the steps of applying a determined amount of liquid to a region on the top side of the article, urging a pressure body (1) against a region of the top side of the article with a given force, and collecting and measuring the amount of liquid pressed out from the top side of the article. The force with which the pressure body (1) is pressed against the top side of the article, is set selectively on a device (2-4) for pressing the pressure body against the top side of the article (20), and the liquid pressed from the top side of the article is transported to a measuring vessel (15) with the aid of sub-pressure.
