This standard specifies a method for determining the flexibility of hot melt adhesives using the mandrel bending method. This standard is applicable to the determination of the flexibility of hot melt adhesives in sheet form under low temperature conditions. Flexibility tests under specified conditions can also be performed by adjusting the test environment device and sample temperature.
