What tests are available?

We can carry out a wide range of tests in accordance with the appropriate standards & guidance documents applicable for the type of connection and fasteners to be installed, supporting you with suitable product performance values to support the necessary calculations to be completed.

Where applicable, typical standards include:

  • SPRA (Single Ply Roofing Association) S15/19 – Site Pull-Out Test Protocol for Flat Roofs

  • BS8539:2012 Code of Practice for the selection and installation of post-installed anchors in concrete and masonry. This is referenced in the CFA (Construction Fixings Association) guidance note

  • BS5427:2016+A1:2017 Code of Practice for the use of profiled sheet for roof and wall cladding

*Tests according to any of these standards may not be necessary where independent test documentation already exists in the form of, e.g., an ETA (European Test Assessment)

From preliminary testing to advice on which fasteners to use for the intended application, to proof testing after the anchors have been installed, we offer an on-site service to support your requirements.
