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.
