ASTM D5635-11Standard Test Method for Dynamic Puncture Resistance of Roofing Membrane Specimens
An important factor affecting the performance of membrane roofing systems is their ability to resist dynamic puncture loads. This test method provides a means to assess dynamic puncture resistance.
This test method can be used to compare the dynamic puncture resistance of a single type of membrane as a function of a variety of insulation substrates or, conversely, to compare the resistance of a number of membrane specimens set on a single type of insulation.
The effect of temperature on puncture resistance can be studied by conducting the test under controlled conditions using such equipment as an environmental chamber, oven, or freezer.
The test method can be useful in developing performance criteria for membrane roofing systems.
The test method can be useful in developing classifications of dynamic puncture resistance of membrane roofing systems.
While it is considered that the results obtained by this laboratory test can afford a measure of the dynamic puncture resistance of membrane roofing systems in the field, (provided that service loads and temperature conditions are known) no direct correlation has yet been established.
This test method can be useful for evaluating the dynamic puncture resistance of membranes used in vegetative roof systems.
