This European Standard specifies the performance requirements and the general requirements of structural design and assessment for prefabricated façade scaffold systems. The façade scaffolds are intended for use while connected to the façade with ties. Scaffold systems are classified by six criteria, see Table 1 It is limited to façade scaffold systems that have standards made of steel or aluminium alloy and have other elements made of these materials or timber based materials. It defines a standard set of system configurations under which the structural design is carried out. Other configurations may be possible with some systems, but they are outside the scope. This standard should be read in conjunction with prEN 12811-1, prEN 12811-2, EN 12811-3 and prEN 12810-2 which specify certain of the requirements. This standard does not specify requirements for protection fans. It does not give information about erection, use, dismantling or maintenance.
