5.2 The manufacturer shall ensure that the food parchment produced meets the requirements of this standard, and each piece of paper shall be accompanied by a certificate of conformity when delivered.
5.3 The sampling inspection of product delivery shall be carried out in accordance with the provisions of GB2828, and the sample unit shall be "piece" or "roll". 5.4 The sampling of samples shall be carried out in accordance with the provisions of GB450. 5.5 The handling of samples and the standard atmosphere of samples shall be carried out in accordance with the provisions of GB10739. 5.6 The qualified quality level (AQL) shall be calculated according to the defective product rate, and the counting sampling plan shall be as specified in Table 2. 5.7 If the purchaser has any objection to the quality, he shall notify the supplier within three months after the arrival of the goods to jointly take samples for inspection of the batch of products. If the inspection results do not meet the requirements of this standard, the batch will be judged as unqualified and the supplier will be responsible for handling it; if the inspection results meet the requirements of this standard, the batch will be judged as qualified and the purchaser will be responsible for handling it.

1 Appearance quality
A2.1 Take a 250mm×250mm sample and place it on a stack of white absorbent paper (5~10 sheets). At room temperature, dip cotton in a 1% magenta glycerol aqueous solution and gently apply it to the sample placed on the white absorbent paper where a 100mm×100mm square
frame is pre-marked. Apply it three times vertically and horizontally, and then calculate the red spots larger than 0.25mm in the square of the white absorbent paper under the sample.
A2.2 Take 5 samples from each piece for testing, and take the arithmetic mean of the test results of the 5 samples as the result. Note ：Glycerol aqueous solution concentration 50%.
