Inorganic fertilizers - Determination of the total K2O content

This document specifies two different methods (Method A and B) for the determination of the content of potassium (expressed as K2O) in inorganic fertilizers. Method A specifies a gravimetric method. Method B specifies the method using inductively coupled plasma optical emission spectrometry (ICP-OES). 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, growing media, inhibitors and plant biostimulants, and where inorganic fertilizers are the highest % in the blend by mass or volume, or in the case of liquid form, by dry mass. If inorganic fertilizers are 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. 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.

Petroleum products - Determination of boiling range distribution - Gas chromatography method (ISO/DIS 3924:2026)

This document specifies a method for the determination of the boiling range distribution of petroleum products. The method is applicable to petroleum products and fractions with a final boiling point of 538 °C or lower at atmospheric pressure as determined by this document. This document does not apply to gasoline samples or gasoline components. The method is limited to products having a boiling range greater than 55 °C and having a vapour pressure sufficiently low to permit sampling at ambient temperature. The document describes two procedures. a) Procedure A allows a larger selection of columns and analysis conditions, such as packed and capillary columns as well as a thermal conductivity detector in addition to the flame ionization detector. Analysis times range from 14 min to 60 min. b) Procedure B is restricted to only three capillary columns and requires no sample dilution. The analysis time is reduced to about 8 min. Both procedures have been successfully applied to samples containing fatty acid methyl esters (FAME) up to 20 % (volume fraction). NOTE For the purposes of this document, the terms "% (mass fraction)" and "% (volume fraction)" are used to represent the mass fraction (µ), the volume fraction (φ) of a material.

Eurocode 9 - Design of aluminium structures - Part 1-5: Shell structures

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. (3) The design procedures are valid only when the requirements for execution in EN 1090-3 or other equivalent requirements are complied with. (4) 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 1090-3, Execution of steel structures and aluminium structures - Part 3: Technical requirements for aluminium structures.
