Introduction
The test is performed on a test configuration, e.g. a load-bearing structure, an air and vapour control layer
(AVCL), a layer of insulation material and the partial or fully bonded roof waterproofing sheets.
The result of this document is the resistance to wind load of the flexible roof waterproofing system
expressed as the characteristic load per square metre. Safety and correction factors can be defined by
national regulation and/or within European or national application documents.
1 Scope
This document specifies the test method to determine the resistance to wind load of the roof build-up
system with the waterproofing system bonded to the substrate.
