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.

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.

ISO 21227-1:2003 gives definitions for and provides guidance in the use of optical imaging systems for the quantitative characterization of defects on coated surfaces that occur after exposure in various test methods, e.g. stone chipping, weathering or cross-cut testing. One aim of ISO 21227 is to use optical imaging to reproduce the results of already existing methods for visual assessment. Additionally, optical imaging provides further information which can be used for a more detailed evaluation of coating defects. This part of ISO 21227 contains a general introduction in optical-imaging methods and definitions. The performance of individual test methods and requirements for precision are described in other parts of the standard.

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.
