This European Standard specifies the requirements for non-alloy steel tubes for use with EN 74 couplers in the construction of falsework and working scaffolds. It includes detailed requirements for marking to aid long term identification, for protective coating by reference to European and International Standards, and for inspection and testing.
NOTE 1: Tubes to this European Standard, which have a specified outside diameter of 48,3 mm and specified thickness of 3,2 mm or 4,0 mm, may also be used in conjunction with other sizes and grades of steel tubes for applications such as prefabricated scaffolds.
NOTE 2: The use of these tubes should be in accordance with appropriate International and national requirements, for example prEN 12811 and prEN 12812.
