This document specifies requirements for the execution i.e. the manufacture and the installation of cold-formed structural aluminium profiled sheeting, and for the installation of structural members made of aluminium for roof, ceiling, floor, wall and cladding applications. This document applies to structures designed according to the EN 1999 series. This document applies to profiled sheeting to be designed according to EN 1999 1 4. This document also specifies requirements for the execution i.e. the manufacture and the installation of structures made from cold-formed profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading or seismic loading conditions and their documentation. This document covers products of Structural Class I and II and structural profiled sheeting in Structural Class III according to EN 1999 1 4 used in structures. NOTE 1 In National Annexes of EN 1999 1 4 specifications can be given regarding the use of the Structural Classes. Structural profiled sheeting is understood here to be profiled sheet, such as trapezoidal or sinusoidal (Figure 1). Perforated and micro profiled sheeting are also covered by this part. This document also covers spacer constructions between the outer and inner or upper and lower skins as well as supporting members for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments of the afore mentioned elements as long as they are involved in load transfer, it also covers connections and attachments of these elements (Figure 2). A combination of steel and aluminium structural profiled sheeting are permitted, e.g. liner trays made of steel, stiffened by profiles made of aluminium. In this case, EN 1090 4 and this document apply. This document also covers the deconstruction of structures made from cold-formed profiled sheeting and structural members for roof, ceiling, floor and wall applications. This document does not cover the manufacturing of structural members of all structural classes according to EN 1999 1 4. These products are covered by EN 1090 3. Welded sections are excluded from this part and are covered by EN 1090 3 except seal welding in low-stress areas. Composite structural profiled sheeting where the interaction between dissimilar materials are an integral part of the structural behaviour such as sandwich panels and composite floors are not covered by this standard. NOTE 2 The structures covered in this standard can be for example - single- or multi-skin roofs, whereby the load-bearing structure (lower skin) as well as the actual roof covering (upper skin) or both consist of structural profiled sheeting; - single- or multi-skin walls whereby the load-bearing structure (inner skin) as well as the actual cladding (outer skin) or both consist of structural profiled sheeting; or - suspended ceilings for interior fitting.

Darbų, susijusių su plieninėmis ir aliumininėmis konstrukcijomis, atlikimas. 4 dalis. Techniniai reikalavimai, keliami stogams, luboms, grindims ir sienoms skirtiems šaltai formuotiems plieniniams konstrukciniams elementams ir šaltai formuotoms konstrukcijoms

This document specifies requirements for the execution, i.e. the manufacture and the installation, of cold-formed structural steel members and profiled sheeting and cold-formed structures for roof, ceiling, floor, wall and cladding applications. This document applies to structures designed according to the EN 1993 series. This document applies to structural members and profiled sheeting designed according to EN 1993 1 3. This document can be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified. This document also specifies requirements for the execution i.e. the manufacture and the installation of structures made from cold-formed profiled sheeting for roof, ceiling, floor and wall applications under predominately static loading or seismic loading conditions and their documentation. This document covers structural profiled sheeting of Structural Class I and II and structural profiled sheeting in Structural Class III according to EN 1993 1 3 used in structures. NOTE 1 In National Annexes of EN 1993 1 3 specifications can be given regarding the use of the Structural Classes. This document covers structural members of all structural classes according to EN 1993 1 3. Structural profiled sheeting is understood here to be: - profiled sheet, such as trapezoidal, sinusoidal or liner trays (Figure 1). Structural members are understood here to be: - members (linear profiled cross sections) that are produced by cold forming (Figure 2). This document also covers: - not welded built-up sections (Figure 2d); - cold-formed closed and hollow sections including the welding of the longitudinal seam (Figure 2b and Figure 2c), not covered by EN 10219 1; — perforated, punctured and micro profiled sheeting and members; The welding of built-up sections are not covered. The welding provisions are given in EN 1090 2. This document also covers spacer constructions between the outer and inner or upper and lower skins for roofs, walls and ceilings made from cold-formed profiled sheeting and the connections and attachments of the afore mentioned elements as long as all has a structural purpose. This document covers steel profiled sheeting for composite floors, e.g. during installation and in stage of pouring concrete. This document also covers the deconstruction of structures made from cold-formed profiled sheeting and structural members for roof, ceiling, floor and wall applications. Composite structural members where the interaction between dissimilar materials are an integral part of the structural behaviour such as sandwich panels and composite floors are not covered by this document. This document does not cover the necessary analyses and detailing and execution rules for thermal insulation, moisture protection, noise control and fire protection. This document does not cover regulations of roof cladding and wall cladding, produced by traditional plumber methods or tinsmith methods. This document does not cover detailed requirements for water tightness or air permeability resistance and thermal aspects of profiled sheeting. NOTE 2 The structures covered in this document can be for example. - single- or multi-skin roofs, whereby the load-bearing structure (lower skin) or the actual roof covering (upper skin) or both consist of cold-formed structural members and profiled sheeting; - single- or multi-skin walls whereby the load-bearing structure (inner skin), the actual cladding (outer skin) or both consist of cold-formed structural members and profiled sheeting, or - trusses from cold-formed members. NOTE 3 Structures can consist of an assembly of structural members and profiled sheeting made of steel according to EN 1090 4 and of aluminium according to EN 1090 5.

Malkomis kūrenamos keliskart įkraunamos saunų krosnelės. Reikalavimai ir bandymo metodai

This European Standard covers multi-firing sauna stoves in which the heating stones are separated from and indirectly heated by the fire and the flue gases and which may be re-fuelled with several fuel loads. This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) of multi-firing sauna stoves fired by wood logs and provides instructions for them. Furthermore, it also gives provisions for evaluation of conformity (i.e. initial type testing (ITT) and factory production control (FPC) and marking of these products. This standard is applicable to hand-fuelled intermittent burning multi-firing sauna stoves, which provide heat into the space where they are installed. These multi-firing sauna stoves may be supplied either as an assembled appliance or as a manufacturer’s pre-designed unit consisting of pre-fabricated components designed to be built on site in accordance with the manufacturer’s specified assembly instructions. One-off installations are not included. These multi-firing sauna stoves may burn only natural wood logs in accordance with the appliance operating instructions. Single-firing heat storage sauna stoves, in which the stones are directly heated by the fire and the flue gases, which pass through them, are not covered by this European Standard. This standard is also not applicable to mechanically fed sauna stoves, sauna stoves having fan assisted combustion air, sauna stoves fitted with a boiler, sauna stoves with incorporated flue or sauna stoves having any electrical connection.
