6.5 The user has the right to check whether the quality of the batch of products meets the requirements of this standard. If the user has any objection to the quality of the products, he should notify the manufacturer to take samples for re-inspection within three months after the arrival of the goods. If it does not meet the requirements of this standard, it will be judged as a batch unqualified and the manufacturer will be responsible for handling it. 7 Marking, packaging, transportation, storage
7.1 The packaging and marking of single-sided offset printing paper shall be carried out in accordance with the provisions of GB/T10342 or the requirements of the order contract. 7.2 The paper should be properly stored to prevent the deterioration of the paper due to the influence of rain, snow and ground moisture. 7.3 During transportation, a canopied and clean transportation vehicle should be used. It is strictly forbidden to drop from a high place during unloading. 7.4 If the product deteriorates or is otherwise damaged due to storage and transportation not meeting the requirements of this standard, the party responsible for the loss shall be held responsible. Additional Notes:
This standard was proposed by the Papermaking Bureau of the Ministry of Light Industry. This standard is under the jurisdiction of the National Papermaking Standardization Center. This standard was drafted by Dandong Paper Mill. This standard is based on the Soviet standard rOCT9094-1970 "Offset Printing Paper". From the date of implementation of this standard, the former Ministry of Light Industry standard QB26-1973 "Single-sided Offset Printing Paper" will be invalid. 552
