1.1 Scope of EN 1991-1-4 (1) This document gives rules for the determination of natural wind actions for the structural design of building and civil engineering works for each of the loaded areas under consideration. This includes actions applied to the whole structure or parts of it, as well as wind-exposed elements attached to the structure. (2) This document is applicable to: - buildings and other civil engineering works with heights up to 200 m; - guyed masts, other open lattice structures and chimneys with heights up to 300 m; - bridges having no span greater than 200 m. (3) The rules contained in this document allow the evaluation of characteristic wind actions on land-based structures. (4) This document is applicable to offshore coastal structures. NOTE Additional or amended provisions can be necessary. (5) This document does not give guidance on non-synoptic winds (e.g. thunderstorms, downbursts, microbursts, tornadoes, etc.), mixed wind climates, nor does it give guidance on how to account for local effects (e.g. thermal effects, funnelling, strong arctic thermal surface inversion, etc.). (6) This document addresses simplified procedures for dynamic effects, mostly based on the assumption of a dominant single-mode response (see Annex E, Annex F and Annex G). General criteria for performing a full dynamic analysis under aerodynamic excitation are not treated in this document. (7) Wind pressure effects of passing vehicles are outside the scope of this document. NOTE See EN 1991 2 for wind effects from passing trains. 8) This document also provides guidance on wind tunnel testing and numerical modelling which can be needed or desirable when the shape or structural behaviour are unusual or do not strictly fall within the rules of the document, or in cases of unusual orography or other surroundings. 1.2 Assumptions (1) The assumptions given in EN 1990-1:2023+A1:2026, 1.2 apply.

This document specifies a method for the determination of the total nitrogen content and the content of ammoniacal, nitric, ureic and organic nitrogen in organic and organo-mineral fertilizers. This document is applicable to fertilizing product blends, where the blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, biostimulants and where the following category organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. This document is applicable to products that at least contain a total nitrogen content of 1 % by mass. In case of fertilizing product blends, it is unattainable to ascertain the origin of the measured nitrogen with respect to the specific component. NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

 

This European Standard specifies tests for adhesives for wood and derived timber products for the assessment of their resistance to hot and cold water.

If fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed only of inorganic products, the European Standard for inorganic fertilizers applies. NOTE Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

 

This document specifies a framework of additional characteristics and associated test methods for bitumens and bituminous binders, which is complementary to other product standards for bitumens and bituminous binders. This document is applicable to bitumens and bituminous binders suitable for use in paving applications, but it is also applicable for other uses such as waterproofing membranes. With regard to paving applications, the following characteristics are addressed: - resistance to permanent deformation (rutting); - resistance to low-temperature cracking; - resistance to ravelling; - resistance to fatigue cracking; - temperature susceptibility; - equi-stiffness temperature and phase angle; - durability (evolution of equi-stiffness temperature and phase angle); - mixing and handling characteristics (paving and compaction) temperatures; - additional characteristics (e.g. solubility, elastic recovery and storage stability). Not all the properties and characteristics established in the framework are universally relevant to all binders. For example, elastic recovery is not relevant for unmodified binders.

This document specifies the requirements for the exchange of mathematical models between a payload contractor (PLC) and a launch service provider (LSP). It identifies standard methods for modelling the dynamic behaviour of both launch vehicle (LV) and payload (PL), particularly when they are coupled prior to launch and during the early moments of the launch phase. In the model exchange case, the delivered models represent dynamic and static behaviour at the launch vehicle interface. The requirements provided in this document are the minimum necessary for dynamic coupled analysis. They may not be sufficient for stress analysis. The payload models are fully integrated models from the different parts of the payload under the payload contractor authority, including the payload adapter to the LV interface, where the adapter is part of the payload. This document does not include the validation of PL models.
