The study demonstrates that the new replica provides results comparable to those obtained using the previous AATCC Stain Release Replica scale. The overall standard deviation for the new replica was lower than that for the previous replica, suggesting less variability and more discrete determinations. Similarly, the range of individual values for the new replica (minimum to maximum) was narrower than the range from the previous replica, suggesting better precision or less scatter.

Labs using this test method should remember that it is important to replace the stain release replica every 12 months and to store the replica in the dark to prevent fading, as recommended in TM 130.

AATCC sends a grateful thank you to the following laboratories that participated in the development of the new Stain Release Replica: SGS Consumer Testing Services, Manufacturing Solutions Center, Hanesbrands Inc., Cintas Corporation, Cotton Incorporated, and 3M.
