This document specifies a reference to the method for the determination of the following specific parameters in inorganic fertilizers: — granulometry; — organic carbon content; — dry matter content. 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: inorganic fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic 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.

 

This document is applicable to the sampling of solid fertilizers and liming materials that have a uniform composition and have no tendency to segregate. NOTE 1 The term product is used throughout the body of this document and is understood to include fertilizers, liming materials and inhibitors unless otherwise indicated. NOTE 2 Manufacturers, importers and sellers can choose to use this method to obtain samples of other products or blends as well as long as both parties to a transaction agree. The build-up of a static heap often leads to granulometric segregation, which makes the collection of a truly representative sample of many products and blends unlikely. NOTE 3 It is the responsibility of manufacturers, importers and sellers, however, to ensure they supply a product that complies with its label declaration at the moment of delivery and fulfils the expectations of the end user at the moment of application. NOTE 4 A method of obtaining a screening sample from a static heap can be found in Annex B.

 

This document specifies a method for the determination of total organic carbon content by elemental analysis using dry combustion. The method is applicable to inorganic fertilizers containing more than 0,1 % carbon expressed on dry mass. NOTE This method can also be applied to other types of fertilizers, 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: inorganic fertilizers, organic fertilizers, organo-mineral fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants and where the following category: inorganic fertilizer is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If inorganic 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.

 

This document defines terms that are used in the field of pigments, dyestuffs and extenders. For some terms, reference is made to ISO 4618 in which also terms and definitions for colourants are given, relating to their use in coating materials.

 

This document applies to the industry producing colouring materials and the consumer who uses the products of this industry. In this document, the colouring materials are classified in accordance with colouristic and chemical aspects. Some dyestuffs for use in the ceramics and food industries are listed as examples.

 

Procedure for comparing the colour of a coloured pigment with that of an agreed sample. The procedures described in this document are acceptable but the method using an automatic muller is the reference method. The binder is not specified. It shall be agreed between the interested parties. If no binder is agreed, linseed oil, complying with the specification in ISO 150, should be used. - Replaces ISO/R 787/1:1968.

 

This document specifies a general method of test for determining the pH value of an aqueous suspension of a sample of pigment or extender.

 

This document specifies requirements and corresponding methods of test for fumed alumina in powder form for paints and varnishes application.

 

This document specifies a general method of test for comparing the colour of a coloured pigment with that of an agreed sample. Either of the procedures described in Clause 6 and Clause 7 is acceptable but the method using an automatic muller is the reference method.

 

This document specifies a general method of test for determining the pH value of an aqueous suspension of a sample of pigment or extender.

 

This document specifies general test methods for determining the resistance to water, acid, alkali-and solvent of pigments.

 

This document specifies a method to measure the total unsaturation of polyether polyols for use in the production of polyurethanes by a Raman spectrometric method. It is not applicable to unsaturated compounds that are conjugated with a carbonyl group, a carboxyl group, or a nitrile group.
