What is ISO 17190-7 about?
ISO 17190 discusses polyacrylate superabsorbent powders for urine-absorbing aids for incontinence. ISO 17190-7 provides a test method that determines the capacity of polyacrylate superabsorbent powders to absorb saline solution under a specified enclosing pressure.
In the given test method, uniform pressure is applied to the test portion. The cylinder is then placed on a filter plate, which is placed in a Petri dish filled with saline solution. After an absorption time of 1 hour, the cylinder is removed from the filter plate and weighed to determine the amount of fluid absorbed.
