European Technical Assessment ETA-15/0091 for anchors in a redundant non-structural system in concrete:
- Static and quasi-static load
- Fire resistance: R30, R60, R90, R120
Tensile capacity in hollow core concrete slabs - expert report no. 21641 - 2016
- It is preferable to install the W-BS Compact manually
- If a cordless drill driver is used for assembly, at least five preliminary tests should be performed on location to ensure the correct drill driver settings and to prevent over-tightening of the W-BS Compact. It is recommended that you start with the drill driver's lowest torque setting and increase it if necessary
- Do not use a tangential impact driver for installation

Datasheets(X)
Anchors in a redundant non-structural system, with European Technical Assessment:
- In normal weight concrete C20/25 to C50/60 (cracked and uncracked concrete)
- Fastenings under exposure to fire
Suitable for mounting low loads in concrete:
Economical and efficient mounting solution for many electrical, plumbing and HVAC applications or attachments that have to be demountable:
- Type P: Mounting of metal profiles, mounting rails, vernier hangers, sheet metal, etc. in in-place installation
- Type LP with large pan head: Mounting attachments such as mounting rails, profiles, sheet metal, etc. if a large contact surface is required
- Type SP with small pan head: Mounting attachments such as metal multiple cable holders, cable clamps, pipe clamps, cable clips, ceiling hangers, profiles, brackets, etc.
W-BS Compact (zinc-plated steel) may only be used in dry indoor conditions.
