Sampling is done in batches, and the manufacturer takes the products mixed evenly at one time as a batch. The number of sampling barrels in each batch shall comply with the provisions of 6.6 of GB/T6678-1986. The packaging of the sampled product must be intact. Do not allow foreign impurities to fall into the product during sampling. Use a probe to collect samples from the top, middle and bottom parts. The sampling volume shall not be less than 200. Finely scoop the obtained samples and pack them into two clean, dry and well-sealed containers. Paste labels on them, indicating the product name, manufacturer name, batch, sampling date and location. One is used for inspection and the other is kept for future reference.
