PD CEN/TS 17659:2021 PDF Download

PD CEN/TS 17659:2021 is a design guideline for mechanically fastened roof waterproofing systems. It focuses on providing guidance on the design of a roof waterproofing system that is mechanically fastened to the structural deck, specifically in relation to wind load resistance. This standard is intended to be used in conjunction with EN 16002 and the relevant clauses of EAD-030351-00-0402-2019.

It is important to note that PD CEN/TS 17659 does not cover separate fastening requirements for insulation boards, securement to upstands, perimeter fastening, flashings, or other roof details.

The standard is targeted towards builders, civil engineers, and manufacturers of fasteners. It serves as a useful tool for designing a roof with a mechanically fastened waterproofing system by providing technical specifications and guidelines.

PD CEN/TS 17659 includes design values for wind pressure and velocity, as well as the determination of the authoritative admissible (design) value for the waterproofing system. It outlines various methods for determining these values, such as full-scale dynamic wind load system testing, using data from fastener manufacturer's ETA, or on-site field pull-out testing of the fastener. The standard also addresses the measurement of fastener density and positioning.
