The ASTM D3811/D3811M-21a standard test method is used to determine the force required to develop a roll of pressure-sensitive tape. This method simulates the situation of manual and machine low-speed Development tape. During the test, the force requirement is related to the development speed, and different types and manufacturers of tape may show different Responses. This method is suitable for verifying the performance of the tape at low-speed Development, but not for high-speed Development comparison. The standard provides test procedures, but does not address all safety issues. Users need to establish their own corresponding safety and environment specifications.
