BS 1139-1.2 is applicable to metal scaffolding of aluminium tube
BS 1139-1.2 specifies requirements for the material, dimensions, and method of manufacture of extruded aluminium tubes for use in scaffolding. BS 1139-1.2 specifies one grade of material and one range of dimensions. Appendix A describes a drift expanding test for extruded aluminium scaffold tubes.
BS 1139-1.2 on the aluminium tube is useful for:
Aluminium tubes are a lightweight option that gives the area a modern feel. A number of fasteners are available for the threaded tube. Aluminium pipe is a machined component that is frequently employed in a variety of industrial projects where weight and corrosion resistance are important.
BS 1139-1.2 specifies requirements for the design, construction, and testing of equipment this will assist you in the use of scaffolding and other temporary structures. BS 1139-1.2 also specifies requirements for aluminium tubing of the type traditionally used in tube and fitting scaffolding.
Overall, BS 1139-1.2 helps you to expand the end of a tube or test piece using a conical mandrel until it tears or splits.
