The number of sampling barrels for each batch shall comply with the provisions of 3. subsection of Taiwan F5678-19F. The packaging of the sampled products must be intact, and the sampling time must be such that the outside world is close to the product. The sampling is carried out from the upper, middle and lower parts with a probe. The total amount of the sampled products should be less than 233. The sampled products should be fully scalded and divided into containers that are clean, dry, light-resistant and well-sealed. The containers shall be marked with the product name, batch number, sampling date and place, and the samples shall be kept for inspection. Www.bzxZ.net
