The Exchange Test Method

LABORATORY TEST METHOD NO. H-5: ABSORBENCY RATE - SANITARY PRODUCTS

  1. PURPOSE:

    To determine rate at which liquid is absorbed by the sanitary products.
  2. PRINCIPLE:

    The test specimens are partially submerged to a predetermined depth into 1% saline solution for a predetermined amount of time and allowed to absorb solution by wicking, under controlled conditions. The higher the rate of absorbency, the better a specimen is, because a specimen's ability to keep the user dry is directly dependent upon the rate of absorbency.
  3. APPARATUS AND MATERIALS:

  4. PROCEDURE:

  5. EVALUATION:

    Calculate the amount of solution picked up by subtracting dry specimen weight from wet specimen.
  6. REPORT

    The absorbency rate is reported as the amount of solution picked up (absorbed by the specimen) in two minutes.
