Tracked Changes. High-strength structural bolting assemblies for preloading – Suitability for preloading
| Published By | Publication Date | Number of Pages |
| BSI | 2020 | 51 |
This European Standard specifies the technical requirements for high-strength structural bolting assemblies in order to ensure the suitability for preloading of bolted connections in metallic structures. A suitability test is specified to check the behaviour of the structural bolting assemblies so as to ensure that the required preload can be reliably obtained by the tightening methods specified in EN 1090 2 with sufficient margins against overtightening and against failure.
