This document specifies a method for the extraction and determination of phosphonates (P-PO3) in fertilizers, liming materials and inhibitors using ion chromatography and conductivity detection (IC-CD). 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 the following category, fertilizers, liming materials and inhibitors, is the highest % in the blend by mass or volume, or in the case of liquid form, by dry mass. If fertilizers, liming materials and inhibitors 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. 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.

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.

This International Standard specifies the assessment of wind loads on cranes. It establishes general methods for calculating wind loads (for in-service and out-of-service conditions), which are included in the load combinations stated in ISO 8686 series and used for proofs of competence such as those given in ISO 20332 for the structural components of cranes. It provides a simplified method of calculation and assumes that — the wind may blow horizontally from any direction, — the wind blows at a constant speed, — there is a static reaction to the wind load applied to the crane structure. It includes built-in allowances for the effects of gusting (fluctuation in wind speed) and for dynamic response. It gives guidance on when to secure the crane for out-of-service conditions.

 

This document specifies a classification system for methods used primarily for the measurement of surface topography and surface texture. It defines three classes of methods, namely, areal-topography methods, volumetric methods and area integrating methods, illustrates the relationships between the classes, and briefly describes specific methods. In addition, this document specifies the elements required for a functional surface texture measurement system.

 

This standard specifies a method for measuring the solar heat gain coefficient for fenestration systems (e.g. complete windows and doors, and curtain walls with or without shading devices) using natural solar radiation. It applies to fenestration systems which might consist of: a) various types of glazing (e.g. glass or plastic; single or multiple glazing; with/without low emissivity coatings, and with spaces filled with air or other gases, or evacuated); b) various types of opaque panels (e.g. door panel, metallic panel); c) various types of frames (wood, plastic, metallic with/without thermal barrier or any combination of materials); d) various types of shading devices (e.g. blind, screen, film or any attachment with shading effects); e) various types of active solar fenestration systems (e.g. building-integrated PV systems (BIPV) or building-integrated solar thermal collectors (BIST)).

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 (f) of a material.

This document specifies methods for determining the pot life of multi-part adhesives, in order to be able to determine whether the pot life conforms to the minimum specified working life required for a specific bonding process or to determine the reactivity of a multi-component adhesive as part of an incoming or outgoing goods inspection. The different methods described in this document to measure the property do not necessarily provide identical results. The test methods described are suitable for assessing all multi–part adhesives, and especially epoxy based and polyurethane based adhesives, but they may not suitable for some acrylic-based adhesives. NOTE 1 Some of the methods described in this document can also be suitable for determination of working life of one-part adhesives that react to humidity (e.g. PUR prepolymers). NOTE 2 This document can also be used for assessing non-structural adhesives.
