Aerospace series - Test methods for metallic materials - Constant amplitude strain-controlled low cycle fatigue testing

This document applies to uniaxial strain-controlled low cycle fatigue testing of metallic materials governed by EN aerospace standards. It defines the properties that need to be determined and the terms used in describing the tests and test pieces. It specifies the equipment, the test pieces, the method of testing and the presentation of results. It applies to testing at ambient and elevated temperatures. The purpose of this document is to ensure the comparability and reproducibility of the test results. It does not cover the evaluation or interpretation of the results. This document is restricted to the use of test pieces having a circular cross-section. In some particular cases the practice can be applied to flat test pieces. The major difficulties concern the preparation of the test pieces and their alignment in the grips.

Organo-mineral fertilizers - Extraction of phosphorus soluble in a neutral ammonium citrate solution

This document specifies the procedure for the extraction of different organic and organo-mineral fertilizers with a solution of neutral ammonium citrate to enable a subsequent determination of phosphorus. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil Improvers, growing media, inhibitors, plant 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. 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.

Eurocode 3 - Design of steel structures - Part 1-5: Plated structural elements

1.1 Scope of EN 1993-1-5 (1) This document provides rules for structural design of stiffened and unstiffened nominally flat plates which are subject to in-plane forces. (2) Non-uniform stress distributions due to shear lag, in-plane load introduction and plate buckling are covered. The effects of out-of-plane loading are outside the scope of this document. NOTE 1 The rules in this part complement the rules for class 1, 2, 3 and 4 sections, see EN 1993-1-1. NOTE 2 For the design of slender plates which are subject to repeated direct stress and/or shear and also fatigue due to out-of-plane bending of plate elements ("breathing"), see EN 1993-2 and EN 1993-6. NOTE 3 For the effects of out-of-plane loading and for the combination of in-plane effects and out-of-plane loading effects, see EN 1993-2 and EN 1993-1-7. (3) Single plate elements are considered as nominally flat where the curvature radius r in the direction perpendicular to the compression satisfies, as illustrated in Figure 1.1: r≥b^2/t (1.1) where b is the panel width; t is the plate thickness. Figure 1.1 - Definition of plate curvature 1.2 Assumptions (1) Unless specifically stated, EN 1990, the EN 1991 series and EN 1993-1-1 apply. (2) The design methods given in EN 1993-1-5 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 the EN 1993 series or in the relevant material product specifications.

Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs) - Part 1: General rules

This document gives general requirements and tests for residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (hereafter referred to as RCCBs), for rated operational voltages not exceeding 440 V AC, with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A, intended principally for protection against shock hazard. RCCBs are intended to provide fault protection (previously referred to as protection against indirect contact), the exposed conductive parts of the installation being connected to an appropriate earth electrode. They are also intended to be used to provide protection against fire hazards due to a persistent earth fault current. RCCBs having a rated residual operating current not exceeding 30 mA are used for fault protection and additional protection in the case of failure of the protective provisions against electric shock. This document applies to RCCBs performing simultaneously the functions of detection of the residual current, of comparison of the value of this current with the residual operating value and of opening of the protected circuit when the residual current exceeds this value. RCCBs are intended to be operated by ordinary or uninstructed persons and designed not to require maintenance. The requirements of this document apply for standard conditions (see 7.1). Additional requirements can be necessary for RCCBs used in locations which have severe environmental conditions. RCCBs within the scope of this document are intended for use in an environment with pollution degree 2 (see 7.3). RCCBs are suitable for isolation. Special precautions (e.g. surge protective devices) can be necessary when excessive overvoltages are likely to occur on the supply side (for example in the case of supply through overhead lines, see IEC 60364-4-44 and IEC 60364-5-53). RCCBs, with the exception of those with an uninterrupted neutral, are suitable for use in IT systems. RCCBs of the general type are resistant to current surges, including the case where surge voltages (as a result of switching transients or induced by lightning) cause loading currents in the installation without occurrence of flashover. RCCBs of type S are considered to be sufficiently resistant against unwanted tripping even if the surge voltage causes a flashover and a follow-on current occurs. Particular requirements are necessary for RCCBs intended to be used at frequencies other than 50 Hz or 60 Hz. For RCCBs incorporated in, or intended for association with socket-outlets only, the requirements of this document can be used, as far as applicable, in conjunction with the requirements of IEC 60884-1 or the national requirements of the country where the product is placed on the market. This document does not apply to: – RCCBs the current setting of which is adjustable without a tool; – RCCBs including batteries. This document is not intended to be used alone; it is intended to be used in conjunction with the relevant product standard, IEC 61008-2-1 or IEC 61008-2-2.

Organic and organo-mineral fertilizers - Determination of the content of specific elements by ICP-AES after extraction by water and weak solvents

This document specifies a method for the determination of boron (B), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), phosphorous (P) and zinc (Zn) in organic and organo-mineral fertilizers using inductively coupled plasma-atomic emission spectrometry (ICP-AES). NOTE 1 Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results. This method is applicable to extracts prepared according to prEN 17766, prEN 17767 and prEN 17779. NOTE 2 The method can be used for the determination of other elements, provided the user has verified the applicability. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant 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.
