§4.1.2 Sampling methodology

As Figure 21 covers the whole testing programme according to EN 14899:2005 in general, a more detailed focus should be drawn on the sampling methodology, which consists of three key elements as displayed in Figure 22: 1. define the sampling plan; 2. take a field sample in accordance with the sampling plan; 3. transport the laboratory sample to the laboratory. Each key element is divided in further sub-elements one should follow to obtain standardised sampling results. Especially for defining the sampling plan several steps have to be performed. An informative template for a sampling plan is displayed in Annex A to EN 14899:2005. Figure 22 presents all sub-elements according to EN 14899:2005 and references to the corresponding technical report, where more detailed information can be found. Please note that Figure 22 (key elements including the definition of a sampling plan) has to be considered as a more detailed segment of the overall testing programme as presented in Figure 21. Also note that EN 15002:2015 gives further guidance on how to prepare test portions from the laboratory sample (see Step 4 in Figure 21) which will be the next step after the preparing and applying the sampling methodology as it will be presented in detail in Figure 22).
