Eurocode 1 - Actions on structures - Part 1-8: Actions from waves and currents on coastal structures

1.1 Scope of EN 1991 1 8 (1) EN 1991 1 8 gives principles and rules to determine the values of wave and current actions on structures and civil engineering works in the coastal zone, i.e. works connected to, or in close vicinity to the shore. NOTE 1 Provisions in EN 1991 1 8 are limited to hydrodynamic actions that can be directly quantified in terms of wave and/or current induced pressures and associated forces and moments on structures or structural parts. NOTE 2 As opposed to offshore conditions, waves or currents in the coastal zone are generally affected by the presence of the seabed or shore. NOTE 3 The coastal zone is typically defined as the area between the shoreline and the deep-water limit. (2) EN 1991 1 8 describes the principles for defining the hydrodynamic conditions to be used for design, including sea water levels. (3) EN 1991 1 8 addresses specifically actions from currents and waves on the following structure types: — cylindrical structures; — subsea pipelines; — suspended decks; — vertical face structures; — permanently moored floating structures. NOTE 1 Additional guidance can be needed for: — moored structures in the coastal zone for renewable energy production or related to oil and gas production or processing; — moored structures spanning areas with variable wave and current states (e.g. floating aquaculture farms or floating bridges). NOTE 2 For hydraulic pressures caused by quasi-static water levels, and ground water, see EN 1997 (all parts). (4) Actions addressed in EN 1991 1 8 do not cover: — hydraulic resonance in sheltered areas or basins (phenomena also known as harbour resonance); — translation waves, e.g. tsunamis; — waves and currents induced by maritime operations, i.e. vessel wake, berthing and mooring; — hydrodynamic actions induced by earthquakes; — ice-induced pressures and forces; — coastal structures where flood risk and/or erosion or sediment management is the dominant function. 1.2 Assumptions (1) The assumptions given in EN 1990 apply to this document. (2) In addition, it is assumed that actions from waves and currents on coastal structures are determined by personnel appropriately qualified and experienced in the following fields: a) physical coastal environment including physics of waves and currents, statistical properties and propagation of such; b) marine hydrodynamics, wave and current interaction with structures in general and wave and current actions on structures in the coastal zone including i) fixed structures, and ii) floating structures; c) advanced methods including probabilistic methodology and physical model testing.

Eurocode 3 - Design of steel structures - Part 4-1: Silos

1.1 Scope of EN 1993 4 1 (1) prEN 1993 4 1 provides rules for the structural design of steel silos of circular or rectangular plan-form, being free-standing (on ground) or supported on a structural framework (elevated). (2) prEN 1993 4 1 is applicable to silos constructed from isotropic rolled plates that are stiffened or unstiffened, from corrugated sheeting that is stiffened or unstiffened and from flat or corrugated plates assembled into box structures of different geometries. It applies to vertical walls, hoppers, roof structures, transition junctions and support structures. (3) prEN 1993 4 1 does not apply to storage vessels for silage and haylage, or to the storage of materials that are not free-flowing (see EN 1991 4). This Part 4-1 also does not cover: - resistance to fire; - cylindrical silos with internal subdivisions; - internal structures within a single silo (except for internal ties, as defined in 12.5); - silos with capacity less than 100 kN (10 tonnes); - hoppers that are supported on a structural framework; - cases where special measures are necessary to limit the consequences of accidents. (4) This document is applicable to silos within the following dimensional limits (see EN 1991-4): - Silo aspect ratio hb/dc < 10 - Silo total height hb < 70 m - Silo equivalent diameter dc < 60 m NOTE These dimensional limitations are more limited than those of EN 1991-4 which also applies to silos constructed from other materials. (5) Where this standard applies to circular planform silos, the geometric form is restricted to axisymmetric structures, but unsymmetrical actions on them and supports that induce forces in the silo structure that are not axisymmetric are included. (6) This part is concerned only with the requirements for resistance and stability of steel silos. For other requirements (such as operational safety, functional performance, fabrication and erection, quality control, details like man-holes, flanges, filling devices, outlet gates and feeders, etc.), see other relevant standards and information. (7) This part is concerned with both isolated silo structures and silos that are connected to others to form a battery of silos, but throughout this document the term silo refers to a single cell within a battery. (8) Provisions relating to special requirements of seismic design are provided in EN 1998 4, which complements or adapts the provisions of Eurocode 3 specifically for this purpose. (9) The structural design of supporting structures for the silo are dealt with in EN 1993 1 1. The supporting structure is deemed to consist of all structural elements beneath the bottom flange of the lowest ring of the silo (see Figure 1.1), though information on some forms of support structure is given in Clause 8 of this document. (10) Foundations in reinforced concrete for steel silos are dealt with in EN 1992 (all parts) and EN 1997 (all parts). 1.2 Assumptions (1) Unless specifically stated, the provisions of EN 1990, EN 1991 (all parts) and EN 1993 1 (all parts) apply. (2) The design methods given in EN 1993 4 1 are applicable if: - the execution quality is as specified in EN 1090 2, and - the construction materials and products used are as specified in the relevant parts of EN 1993 (all parts), or in the relevant material and product specifications.

Methods of testing cement - Part 15 - Sulfate resistance - Flat prism method

This document describes test methods (reference and alternative) applicable to cast test specimens for evaluating the Sulftate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks. In these methods, the test is carried out under controlled exposure conditions using an increased concentration of sulfate solution. These test conditions are intended to accelerate external sulfate attack. The reference test method is adapted from the modified SVA test method (German Institute for Building Technology (DIBt), Expert Committee (SVA)): “Testing the Sulfate Resistance of Cements with pozzolanic main constituents”. The modified SVA test method is listed in European Assessment Document – EAD 150007-01-0301, Annex C. This test method is appropriate for various binders, in particular those with pozzolanic main constituents. The alternative test method is listed in European Assessment Document – EAD 150009-01-0301, Annex A. This test method is appropriate for CEM III/A cements.

Leather - Chemical tests for the determination of certain azo colorants in dyed leathers - Part 2: Determination of 4-aminoazobenzene (ISO/DIS 17234-2:2026)

ISO 17234-2:2011 is supplementary to ISO 17234-1 and describes a special procedure to detect the use of certain azo colorants in commodities, which can release 4-aminoazobenzene. The procedure also detects 4-aminoazobenzene (Solvent Yellow 1) which is already available as free amine in commodities without reducing pretreatment. Azo colorants that are able to form 4-aminoazobenzene generate, under the conditions of ISO 17234‑1, the amines aniline and 1,4-phenylenediamine. The presence of these 4-aminoazobenzene colorants cannot be reliably ascertained without additional information (e.g. the chemical structure of the colorant used) or without a special procedure.
