This standard specifies a series of test methods for determining the adhesive retention capability of adhesive tapes under constant parallel loads. Based on the "gravity shear method," the standard involves vertically suspending a test plate with the sample attached, connecting a loading plate and standard weights of specified mass to its lower end, and then using specialized instruments to record the time required for the sample to produce a specific displacement or completely detach. This quantifies the adhesive retention performance of the tape. The key instrument for conducting this test is the adhesive retention tester, which typically includes multiple independent stations, a microcomputer control system, and a timer to meet the standard's requirements for test conditions and automated operation. This method is applicable to various adhesive products, such as pressure-sensitive tapes and medical patches, for evaluating their resistance to creep and pull-off.
