CEN/TC 254/WG 5 - Static puncture resistance, dynamic puncture (impact) resistance and hail resistance

This document specifies a test for determining the ability of flexible sheets to remain watertight after being stretched at low temperature.
This standard is applicable only for mechanically fastened single layer waterproofing.
This standard has been drafted for application in roofing, but it may also be used in other areas where it is relevant.

This European Standard specifies a test for puncture by impact on sheets for roof waterproofing. Mechanical stress on waterproofing sheets ranges from static long-term loads to dynamic short-term loads. This method represents the dynamic category of load where puncture may be caused by impact.
This European Standard may also be applied for other purposes of waterproofing.

This European Standard specifies a test for puncture by static loading for roofing membranes. Mechanical stress on membranes varies from static long-term loads to dynamic short-term loads. This method represents the static category of load where the stress is applied over a period of time. This European standard may also be applied for waterproofing.

This European Standard specifies the determination of the resistance of flexible sheets for roofing to hail using a test for puncture by simulated hail.
This European Standard may also be applied for waterproofing.

This European Standard specifies a test for puncture by impact on sheets for roof waterproofing. Mechanical stress on waterproofing sheets varies from static long-term loads to dynamic short-term loads. This method represents the dynamic category of load where puncture is caused by impact.
