EN 74-3:2007 Couplers, spigot pins and baseplates for use in falsework and scaffolds - Part 3: Plain base plates and spigot pins - Requirements and test procedures
EN 74-3 specifies for plain and profiled base plates and loose spigots to be used with 48,3 mm diameter tubes in scaffolds and falsework: materials; design requirements; test procedure; assessment. A base plate with a means of limited vertical adjustment, called a "base jack", is dealt with in EN 12811-1. NOTE In the text of this standard, the term "loose spigot" is used instead of the "spigot pin" in the title.
