NOTE In an interlaboratory st

20、udy 2 the method described has been tested at levels down to 3,5 mg/100 ml, but the precision appeared to be insufficient at such low levels. WARNING Use of this document may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems

21、associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 2 Normative references The following referenced documents are indispensable for the application of

22、 this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 3170, Petroleum liquids Manual sampling (ISO 3170:2004) 3 Principle Dry residue is determined by the weighing of the

23、residue left by evaporation of alcohol on a boiling water bath and drying in a drying oven. Dry residue includes all matter that is non-volatile under specified physical conditions. 4 Apparatus 4.1 Evaporating dish (100 to 250 ml). 4.2 Boiling water bath. 4.3 Pipette, 100 ml, class A. 4.4 Oven, capa

24、ble of being held at a temperature of (103 2) C. 4.5 Desiccator, containing freshly activated silica gel (or equivalent desiccant) with moisture content indicator. 4.6 Analytical balance, capable of weighing with an accuracy of 0,1 mg. 5 Sampling 5.1 Preparation of samples Unless otherwise specified

25、 in the commodity specification, samples shall be taken as described in EN ISO 3170. Collect the samples in glass bottles. Samples shall be stored at room temperature prior to analysis.

26、9EN 15691:2009 (E) 5 5.2 Verification and quality control It is recommended to prepare a sodium chloride solution with a content of 100 mg/l in ethanol from neutral ethanol free of dry residue and from an aqueous sodium chloride solution the content of which is 10 g/l. For example, 10 ml of the aque

27、ous solution can be introduced in 1 l of this neutral alcohol without residue. This is a solution with a dry residue content of 10 mg/100 ml. 6 Procedure Place clean dry evaporating dishes (4.1) into the oven for 30 minutes, then place them into the desiccator (4.5) for 30 minutes. Use a tool to man

28、ipulate dishes, do not touch directly with fingers. Accurately weigh, to the nearest 0,1 mg, the clean dry evaporating dishes (4.1) (M0). Pipette (4.3) 100 ml of sample or quality control and introduce respectively into the dishes. Place the dishes with sample on the boiling water bath (4.2) and all

29、ow to dry. NOTE In general, it takes about two hours to evaporate the alcohol on the water bath. Place the dishes in the oven (4.4) at (103 2) C for 30 minutes and then transfer dishes with residue into a desiccator (4.5). Allow the dishes to cool for 30 minutes and then weigh, to the nearest 0,1 mg

30、, the dishes with residue (M1). 7 Calculation The content of dry residue, D, expressed in mg/100 ml is given by: 01MMD = (1) where D is the expression for dry residue, M1is the mass, in mg, of the dish and residue after drying, M0is the mass, in mg, of the clean dry dish. 8 Expression of results Rep

31、ort the content of dry residue rounded to the nearest 1 mg/100 ml. 9 Precision 9.1 General The precision given was derived from statistical analysis by EN ISO 4259 3 of the results of interlaboratory testing of a matrix of ethanol liquids, produced from biomaterials such as wine (fermentation result

32、), molasses, pulp and corn.

In some occasions the repeatability is larger than the

33、 reproducibility, caused by outliers, but the evaluation did not show major mistakes in the set up of the interlaboratory testing. The term “single test result” means the value obtained when the standardized test method is applied fully once to a single sample. Unless otherwise stated, the probabili

34、ty shall be 95 %. 9.2 Repeatability, r The repeatability limit is the value below which the absolute difference between two single test results obtained under the same conditions (same operator, same apparatus, same laboratory and a short interval of time) should exceed the following value in mg/100

35、 ml in one case in twenty: r = 0,191 X + 0,000 55 (2) where X is the average value of results being compared. 9.3 Reproducibility, R The reproducibility limit is the value below which the absolute difference between two single test results obtained under different conditions (different operators, di

36、fferent apparatus and/or different laboratories and/or different time) should not exceed the following value in mg/100 ml in one case in twenty: R = 0,184 8 X + 0,000 81 (3) where X is the average value of results being compared. 10 Test report The test report shall contain at least the following in

37、formation: a) reference to this European Standard, i.e. EN 15691; b) all information necessary for the complete identification of the sample; c) applied sampling procedure (see 5.1); d) results of the test (see 8); e) any deviation, by agreement or otherwise, from the procedure specified in this Eur
