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: - European Standards for construction products relevant for aluminium structures; - EN 1090-1, Execution of steel structures and aluminium structures - Part 1: Requirements for conformity assessment of structural components; - EN 1090-5, Execution of steel structures and aluminium structures - Part 5: Technical requirements for cold-formed structural aluminium elements and cold-formed structures for roof, ceiling, floor and wall applications.

1.1 Scope of EN 1999-1-5 (1) EN 1999-1-5 applies to the structural design of aluminium structures, stiffened and unstiffened, that have the form of a shell of revolution or of a round panel in monocoque structures. (2) EN 1999-1-5 covers additional provisions to those given in the relevant parts of EN 1999 for design of aluminium structures. NOTE Supplementary information for certain types of shells is given in EN 1993-1-6 and the relevant application parts of EN 1993 which include: - Part 3-1 for towers and masts; - Part 3-2 for chimneys; - Part 4-1 for silos; - Part 4-2 for tanks; - Part 4-3 for pipelines. (4) The provisions in EN 1999-1-5 apply to axisymmetric shells (cylinders, cones, spheres) and associated circular or annular plates, beam section rings and stringer stiffeners, where they form part of the complete structure. (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. (2) The provisions of EN 1999-1-1 apply.

This document specifies methods for determining fracture toughness in terms of K, δ, J and R-curves for homogeneous metallic materials subjected to quasistatic loading. Specimens are notched, precracked by fatigue and tested under slowly increasing displacement. The fracture toughness is determined for individual specimens at or after the onset of ductile crack extension or at the onset of ductile crack instability or unstable crack extension. In cases where cracks grow in a stable manner under ductile tearing conditions, a resistance curve describing fracture toughness as a function of crack extension is measured. In some cases in the testing of ferritic materials, unstable crack extension can occur by cleavage or ductile crack initiation and growth, interrupted by cleavage extension. The fracture toughness at crack arrest is not covered by this document. Special testing requirements and analysis procedures are necessary when testing weldments, and these are described in ISO 15653 which is complementary to this document. Statistical variability of the results strongly depends on the fracture type, for instance, fracture toughness associated with cleavage fracture in ferritic steels can show large variation. For applications that require high reliability, a statistical approach can be used to quantify the variability in fracture toughness in the ductile-to-brittle transition region, such as that given in ASTM E1921. However, it is not the purpose of this document to specify the number of tests to be carried out nor how the results of the tests are to be applied or interpreted.

Human-centred quality is an outcome and a measure of the extent to which requirements for usability, accessibility, user experience and avoidance of harm from use are met. This document describes the rationale, principles and activities needed to improve the human-centred quality of an organisation’s products, systems and services, and the significant business benefits that can be achieved. It provides requirements and recommendations for the principles that management needs to implement for achieving human-centred quality. The principles and activities address the needs of people directly interacting with the outputs of the development process as well as other people who are stakeholders in their operation. While the document is not intended to be directly applicable to organizational design and the design of work systems, it can be adapted for these purposes. It does not provide in detail coverage of the methods and techniques; processes that implement the human centred design approach are described in ISO 9241-220. This document does not address domain-specific health or safety requirements. The information in this document is intended for use by those responsible for planning and managing projects that develop products and services. It provides a framework for ergonomists and human factors professionals involved in human-centred activities to structure their work for integration in project planning and governance. This document operates within the framework of ISO 26800, that sets out the overall principles of ergonomics. The application of detailed ergonomics/human factors knowledge in specific domains can be used in conjunction with this document. These issues are addressed in a number of other TC 159 standards including parts of ISO 9241, ISO 6385, ISO 20282-1, ISO 11428 and ISO TS 20646.
