ASTM D5635/D5635M-18 PDF Download

The ASTM D5635/D5635M-18 standard is a test method used to evaluate the dynamic puncture resistance of roofing membrane specimens. The ability of membrane roofing systems to resist puncture impacts is an important factor in their performance. This test method provides a means to assess the dynamic puncture resistance of different types of membranes.

The standard allows for the comparison of dynamic puncture resistance between different types of membranes or between different membrane specimens set on the same insulation. It also provides the option to study the effect of temperature on puncture resistance by conducting the test under controlled conditions using equipment such as an environmental chamber, oven, or freezer.

The test method is useful for developing performance criteria and classifications for membrane roofing systems based on their puncture resistance. However, while the results obtained from this laboratory test can give an indication of the dynamic puncture resistance of membrane roofing systems in the field, no direct correlation has been established yet.

This standard is applicable to roofing membrane specimens made of various materials, including bituminous built-up, polymer-modified bitumens, vulcanized rubbers, non-vulcanized polymeric, and thermoplastic materials. It can also be used to evaluate the dynamic puncture resistance of membranes used in vegetative roof systems. However, it is not applicable to aggregate-surfaced membrane specimens, though it can be used for specimens with factory-applied granules.
