(1)   EN 1999-1-4 gives design requirements for cold-formed trapezoidal aluminium sheeting. It applies to cold-formed aluminium products made from hot rolled or cold rolled sheet or strip that have been cold-formed by such processes as cold-rolled forming or press-breaking.
NOTE 1   The rules in this part complement the rules in other parts of EN 1999-1.
NOTE 2   The execution of aluminium structures made of cold-formed structures for roof, ceiling, floor and wall applications is covered in EN 1090-5.
(2)   EN 1999-1-4 gives methods for stressed-skin design using aluminium sheeting as a structural diaphragm.
(3)   EN 1999-1-4 does not apply to cold-formed aluminium profiles like C- and Z- profiles nor cold-formed and welded circular or rectangular hollow sections.
(4)   EN 1999-1-4 gives methods for design by calculation and for design assisted by testing. The methods for the design by calculation apply only within stated ranges of material properties and geometrical properties for which sufficient experience and test evidence is available. These limitations do not apply to design by testing.
(5)   EN 1999-1-4 does not cover load arrangement for loads during execution and maintenance.
1.2   Assumptions
(1) For the design of new structures, EN 1999 is intended to be used, for direct application, together with EN 1990, EN 1991, EN 1992, EN 1993, EN 1994, EN 1995, EN 1997 and EN 1998.
EN 1999 is intended to be used in conjunction with:

(5)   Single shell panels (cylindrical, conical or spherical) are not explicitly covered by EN 1999-1-5. However, the provisions can be applicable if the appropriate boundary conditions are duly taken into account.
(6)   Types of shell walls covered in EN 1999-1-5 can be (see Figure 1.1):
-   shell wall constructed from flat rolled sheet with adjacent plates connected with butt welds, termed “isotropic”;
-   shell wall with lap joints formed by connecting adjacent plates with overlapping sections, termed “lap-jointed”;
-   shell wall with stiffeners attached to the outside, termed “externally stiffened” irrespective of the spacing of stiffeners;
-   shell wall with the corrugations running up the meridian, termed “axially corrugated”;
-   shell wall constructed from corrugated sheets with the corrugations running around the shell circumference, termed “circumferentially corrugated”.
[Figure 1.1 - Illustration of cylindrical shell form]
(7)   The provisions of EN 1999-1-5 are intended to be applied within the temperature range defined in EN 1999-1-1. The maximum temperature is restricted so that the influence of creep can be neglected. For structures subject to elevated temperatures associated with fire, see EN 1999-1-2.
(8)   EN 1999-1-5 does not cover the aspect of leakage.
1.2   Assumptions
(1)   The general assumptions of EN 1990 apply.

Execution of steel structures and aluminium structures - Part 4: Technical requirements for cold-formed structural steel elements and cold-formed structures for roof, ceiling, floor and wall applications
SIST EN 1090-4:2018

This European Standard specifies requirements for the execution, i.e. the manufacture and the installation, of cold-formed structural steel members and sheeting and cold-formed structures for roof, ceiling, floor, wall and cladding applications.
This European Standard applies to structures designed according to the EN 1993 series.
This European Standard applies to structural members and sheeting to be designed according to EN 1993 1 3.
This European Standard may 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 European Standard 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 European Standard covers sheeting of structural classes I and II according to EN 1993 1 3 used in structures.
This European Standard covers structural members of all structural classes according to EN 1993 1 3.
Structural sheeting are understood here to be:
-   profiled sheet, such as trapezoidal, sinusoidal or liner trays (Figure 1), or
Structural members are understood here to be:
-   members (linear profiled cross sections) that are produced by cold forming (Figure 2).
This European Standard also covers:
-   not welded built-up sections (Figure 2b and 2c);
-   cold-formed hollow sections including the welding of the longitudinal seam, not covered by EN 10219 1;
-   perforated, punctured and micro profiled sheeting and members;
NOTE 1   Welded built-up sections, are not covered, the execution provisions are given in EN 1090–2.
This European Standard 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 are involved in load transfer.
This European Standard covers steel profiled sheeting for composite floors, e.g. during installation and in stage of pouring concrete.
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 standard.
This European Standard does not cover the necessary analyses and detailing and execution rules for thermal insulation, moisture protection, noise control and fire protection.
This European Standard does not cover regulations of roof cladding and wall cladding, produced by traditional plumber methods or tinsmith methods.
Annex B of this standard concerns provisions which are not yet included in EN 1993 1 3. The guidelines in this annex may be wholly or partially superseded by future guidelines added to EN 1993.
This European Standard does not cover detailed requirements for water tightness or air permeability resistance and thermal aspects of sheeting.
NOTE 2   The structures covered in this standard 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 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 sheeting, or
-   trusses from cold formed members.
NOTE 3   Structures can consist of an assembly of structural members and sheeting made of steel according to EN 1090–4 and of aluminium according to EN 1090-5.

Railway applications - Ride comfort for passengers - Measurement and evaluation
SIST EN 12299:2024

The purpose of this document is to provide methods for quantifying the ride comfort of a passenger in a rail vehicle in response to the track sections it is operated over.
The methods aim to quantify the effects of vehicle body motions on ride comfort and to make the assessment of passenger comfort predictable, repeatable, objective and meaningful.
The methods and comfort scales are validated for people of good health.
This document applies to passengers in rail vehicles operating on heavy rail networks.
This document applies to measurements of motions. It also applies to simulated motions. Guidance is provided on:
-   which method described within the document should be used for different scenarios;
-   typical values for different comfort levels;
-   the application of simulation.
This document excludes health and safety issues, non-passenger carrying vehicles, vehicle homologation and safety, limit values, motion sickness, discomfort caused by accelerating and braking, design guidelines and measurement technology.
