We’ve made big changes to the important European standard for aluminium casting
BS EN 1706:2020 Aluminium and aluminium alloys — Castings — Chemical composition and mechanical properties specifies the chemical composition limits for aluminium casting alloys and the mechanical properties of separately cast test pieces for these alloys. It includes an annex on the selection of alloys for a specific use or process. This standard was first published in 1998 and then revised in 2010. The 2020 standard is its second revision.
