43、on This annex describes the sampling procedures, which shall be used to implement the analysis methodology stated in EN 50625-2-4:2017, 5.6. Sampling shall consider guidance in the following standards: CEN/TR 15310-1 to CEN/TR 15310-5, EN 14899. AA.2 Number and size of samples Samples shall be taken

44、 from fractions resulting from the photovoltaic panel treatment during a batch (see also EN 50625-1:2014, Table D.1) or from longer periods of photovoltaic panel treatment. The population is this whole amount of fraction produced during treatment of a given input amount. As a minimum 10 samples shal

45、l be taken from each treatment fraction being analysed. For each fraction, take the 10 single samples and combine them to form one “mixed sample”. Each of the resulting mixed samples for the different fractions shall be reduced to a size suitable for laboratory analysis (see Table AA.1). The number

46、of samples for analysis depends on the amount of photovoltaic panels treated per year as follows: 1 sample per year for 1 000 t of photovoltaic panels treated per year 1 sample every 6 months for 1 000 10 000 t photovoltaic panels treated per year 1 sample quarterly for 10 000 t photovoltaic panels

47、treated per year The sample size depends on the particles size of the sampled fraction according to Table AA.1.

49、f all sizes expected to be contained in the output stream. Samples shall be taken at the outlet of a continuous mechanical treatment process, directly from the output flow of the fraction on the whole cross section of the flow profile. Each sample shall be taken at regular intervals specified below but avoiding the start and finish of the treatment process. NOTE 1 Start and the finish of the treatment process are less representative because separation results might not be representative dur
