BS EN 15961:2017EN 15961:2017 (E) 4 1 Scope This European Standard specifies a method for the extraction of water-soluble calcium, magnesium, sodium and sulfur (in the form of sulfates), so that the same extract can be used for the determination of each nutrient required. The m
18、ethod is solely applicable to fertilizers listed in Regulation (EC) 2003/2003, Annex I 2), for which a declaration of the water-soluble calcium, magnesium, sodium, and sulfur (in the form of sulfates) is provided for in this Regulation. 2 Normative references The following documents, in whole or in
19、part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1482-2, Fertilizers and liming materials - S

21、definitions For the purposes of this document, the terms and definitions given in EN 12944-1:1999 and EN 12944-2:1999 apply. 4 Principle Extraction of the calcium, magnesium, sodium, and sulfur (present in the form of sulfates) in the fertilizer by boiling in water under the specified conditions. 5
22、Sampling Sampling is not part of the method specified in this document. A recommended sampling method is given in EN 1482-1 1. Sample preparation shall be carried out in accordance with EN 1482-2. Grinding of the laboratory sample is recommended for homogeneity reasons. 6 Reagents 6.1 Water, distill
23、ed or demineralized.

24、lfur or where they contain, at the same time, no more than 3 % of sulfur (S) i.e. 7,5 % SO3, and no more than 4 % of calcium (Ca) i.e. 5,6 % CaO, weigh 5 g of the test sample to the nearest 1 mg. Place it in the beaker (7.3). Where fertilizers contain more than 3 % of sulfur (S) and more than 4 % of
25、 calcium (Ca), weigh 1 g of the test sample to the nearest 1 mg. Place it in the beaker (7.3). 8.2 Preparation of the solution Add approximately 400 ml of water (6.1) to the test portion (8.1) and boil for 30 min. Cover the beaker with a lid to avoid losses during boiling. Allow to cool and let stan
26、d for 24 h at room temperature. Decant quantitatively into a graduated flask (7.4). Make up to volume with water (6.1) and mix. Pass through a filter (7.5) into a dry container. Discard the initial portions of the filtrate. The filtrate shall be completely transparent. Stopper if the filtrate is not
27、 used immediately. 9 Test report The test report shall contain at least the following information: a) all information necessary for the complete identification of the sample; b) test method used with reference to this document; c) test results obtained; d) date of sampling and sampling procedure (if
28、 known); e) date when the analysis was finished; f) whether the requirement of the repeatability limit has been fulfilled; g) all operating details not specified in this document, or regarded as optional, together with details of any incidents occurred when performing the method, which might have in
29、fluenced the test result(s).
