• test In the ten-drop test according to an in-house test method, a 10-well metal stencil is placed on a nonwoven piece as an absorbent layer. In each well of the metal template, one drop of a synthetic urine solution is pipetted successively. A test field counts if the amount of fluid has been absorbed within 2 seconds by the underlying absorption layer. In order to obtain information about the permanence of a fiber preparation, the test is repeated after a waiting time of 3 minutes without replacing the absorption layer. The test result indicates the number of passed test fields.
