Description / Abstract:
This test method covers the evaluation of the maximum dynamic puncture
load that roofing membrane
samples can withstand, without allowing the passage of water, when
subjected to impact from a rigid
object having a sharp edge.
This laboratory test can be conducted at any desired temperature using
membrane samples
manufactured in a factory or prepared in a laboratory.
Roof membrane specimens to which the test method is applicable include
bituminous built-up,
polymer-modified bitumens, vulcanized rubbers, non-vulcanized
polymeric, and thermoplastic
materials.
This test method is not applicable to aggregate-surfaced membrane
specimens; however, it is
applicable to specimens having factory-applied granules.
The values stated in SI units are to be regarded as the standard. The
values given in parentheses
are for information only.
This standard does not purport to address all of the safety concerns,
if any, associated with its
use. It is the responsibility of the user of this standard to
establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
