Each batch of sugar shall be accompanied by the quality certificate of the country of origin. The buyer receives the goods with the quality certificate and conducts sampling inspection at the delivery site. 5.2 Inspection batch Each delivery batch of raw sugar is an inspection batch. 5.3 Sampling 5.3.4 Sampling 5.3.4.1 Overview There are three types of original sampling. systematic sampling, stratified sampling and secondary sampling. One of the sampling types can be selected according to the actual situation. 5.3.4.3 Stratified sampling A batch of raw sugar can be sampled in several layers (not less than 3 layers) in the process of loading-unloading, processing, and stacking, for example, in a cabin. According to the mass of raw sugar contained in each layer, proportionally on the newly exposed surface, distribute points evenly. 5.3.4.5 Special requirements In case of large batches, long loading-unloading time, high temperature and so on, samples shall be taken and kept as soon as possible to prevent evaporation of water. If the cargo is unloaded on rainy days, prevent rain and moisture absorption. 5.3.5 Sample preparation 5.3.5.1 During the sample preparation process, the composition of the sample shall be prevented from changing and contamination. 5.4 Sample inspection 5.4.1 Sample inspection requirements The analysis samples are divided into 3 portions. Inspect according to the test method specified in this Standard. Use the average of the two closest measured values as the final test result of the inspection lot. Or if the difference between two measured values and an intermediate value is equal, then use this intermediate value as the final test result of the inspection lot. This result shall be regarded as the average quality of the batch of raw sugar. 5.4.2 Result determination If the inspection results have nonconforming indicators, double samples shall be taken. 5.4.3 Storage of inspected sample The analysis samples shall be kept in a safe place for inspection. The storage period may be in accordance with relevant regulations but shall not be less than 3 months.6 Marks, packaging, transportation, storage6.1 Marks The label of pre-packaged raw sugar shall meet the requirements of GB 7718.
