This document applies to the design of mobile access and working towers made of prefabricated elements with dimensions which are fixed by the design and with a height up to 12 m (indoors) and up to 8 m (outdoors). This document applies to mobile access and working towers used as temporary work equipment. This document: - gives guidelines for the choice of the main dimensions and stabilizing methods, - gives safety and performance requirements; and - gives information on complete towers. This product standard does not apply to scaffolds according to EN 12810-1 and EN 12811-1.

This document specifies the requirements for products of loose-filled expanded polystyrene (EPS) beads and bonded expanded polystyrene beads for in-situ installation in masonry cavity walls and frame constructions. This document is a specification for the insulation products before installation. It describes the product characteristics and includes procedures for testing, marking and labelling. This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application are to be found in regulations or non-conflicting standards. NOTE To avoid water penetration in masonry walls special tests adjusted to local climate might be needed. This document does not cover factory made expanded polystyrene (EPS) insulation products or factory made or in-situ products intended to be used for the insulation of building equipment and industrial installations. Products with a declared thermal resistance lower than 0,25 m2·K/W or a declared thermal conductivity greater than 0,060 W/(m·K) at 10 °C are not covered by this document. This document does not cover products intended for airborne sound insulation and for acoustic absorption applications.

This document specifies a procedure for carrying out impressed current electrochemical chloride extraction from chloride bearing concrete in existing structures. It is applicable to atmospherically exposed parts of structures with ordinary reinforcement and/or post-tensioned tendon ducts embedded in concrete. In the latter case, it is essential to verify that there is no risk of hydrogen embrittlement, if necessary by conducting trials and installing monitoring during the treatment. This document does not apply to concrete containing pre-stressing steel which can suffer hydrogen embrittlement during chloride extraction, or to concrete containing epoxy-coated or galvanized reinforcement. In case of post-tensioned, pre-stressing concrete, the endangered tendon strands may be shielded by the tendon ducts from unwanted and/ or exceeded polarization into the cathodic range and respective water reduction.
