In addition, this document specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer. The requirements of this document are complementary to the common requirements formulated in EN 1009-1, EN 1009-2, EN 1009-3, EN 1009-4, EN 1009-5. This part does not repeat the requirements from EN 1009-1, but adds or replaces them.

This document specifies tolerances on dimensions and form of extruded precision profiles in alloys EN AW-6060 and EN AW-6063, manufactured with and without a thermal barrier (see Figures 1 and 2). It applies to extruded products supplied without further surface treatment. Precision profiles covered in this document are distinguished from extruded profiles for general applications covered in EN 755-9 by the following characteristics: - they are mainly for architectural applications designed with mostly uniformly wall-thicknesses; - they are mainly used for architecture, mechanical engineering and automotive applications (except structural-parts and crash-elements); - the maximum weight per metre of 10 kg/m; - the max. wall-thickness proportion (S max/S min) of 3,5 mm. In the case of profiles which, due to the complexity of their design, are difficult to manufacture and specify, then special agreements between supplier and purchaser may need to be reached.

This document specifies design criteria for closed water-based cooling systems in buildings. The requirements aim at achieving a proper technical quality level and maintaining the desired thermal indoor climate with minimum energy consumption. Systems for dissipating process heat from industrial processes, for example, are not covered by this document. This document does not amend product standards or product installation requirements. The standard covers cooling systems of the following type (see Figure 1): 1) devices for the water-based heat rejection of the chilling system; 2) devices for chilling and storage of chilled water; 3) devices for the distribution of chilled water; 4) devices for the absorption of heat ("cooling emission"); 5) control devices; 6) safety devices. The design of such systems is described in this document. In the case of water-based cooling systems with local operating temperatures ≤ 0 °C separate safety aspects may apply.

This document specifies sampling and test methods for natural, manufactured and recycled aggregates for use as armourstone. This document specifies the reference methods to be used for type testing and in case of dispute where an alternative method has been used. For other purposes, in particular factory production control, it allows for other methods to be used provided that an appropriate working relationship with the test method has been established. This document provides non-contradictory complementary information that can be of use when producing or purchasing armourstone produced according to harmonised standard prEN 13383-1:2021. NOTE prEN 13383-1:2021 is also intended to be read in conjunction with the Construction Products Regulations.
