3Product classification
Standard atmosphere for pulp, paper and paperboard sample handling and testing3.1 According to processing needs, bobbin base paper is divided into type 1 and type I. 3.2 According to the standard adoption situation and quality level, type 1 base paper has only one grade, and type II base paper is divided into three grades: A, B, and C. 3.3 Bobbin base paper is roll paper, the roll width is 610, 635, 950mm, the width deviation is not allowed to exceed ±3mm, the roll diameter is 800~850mm, and the width and diameter of the roll can also be based on the provisions of the order contract. 4Technical requirements and test methods

4.2 The paper surface should be flat, and there should be no sand, hard blocks, oil wax spots, holes, wrinkles, cracks and other appearance paper defects that affect the use. 4.3 During the reeling process, the non-periodic paper defects that are not easy to find inside the reel shall not exceed 3%. When measuring the paper defects inside the roll, remove the outer 5 layers and then take 5 layers of samples, cut them into 0.05mm2 paper pieces and weigh them, then select and weigh the paper pieces with paper defects and calculate their percentage of the sample.
4.4 There shall be no more than 5 broken ends per roll, and obvious marks shall be made at the broken ends. 4.5 Those with the following conditions can be regarded as second-class products, but no more than two items at the same time. 4.5.1 The quantitative exceeds the standard deviation by less than 2%. 4.5.2 The thickness exceeds the standard by less than 0.01mm. 4.5.3 The tensile strength is less than the standard by less than 10%. 4.5.4 The water absorption is less than or more than ±5mm. 5 Inspection rules
One batch is delivered in batches, but not more than 30t. 5.1
5.2 The manufacturer shall ensure that the products produced meet the requirements of this standard, and a product quality certificate shall be attached to each paper when it is delivered. 5.3 Product delivery inspection sampling shall be carried out in accordance with GB/T2828. 5.4 The delivery unit of bobbin paper is paper.
5.5 The sampling and processing of samples shall be carried out in accordance with GB/T450 and GB/T10739. 5.6 The delivery sampling plan, inspection level and acceptable quality level (AQL) shall be carried out in accordance with Table 2. Table 2

5.7 The purchaser has the right to inspect the product quality according to the provisions of this standard. If there is any objection to the product quality, the manufacturer should be notified within one month after arrival. The supply and demand parties will jointly take samples for re-inspection. If it does not meet the requirements of this standard, it will be judged as a batch nonconforming and the manufacturer will be responsible for handling it; if it meets the requirements of this standard, the purchaser will be responsible for handling it.
6 Marking, packaging, transportation, storage
QB/T1601-1992
6.1 The packaging and marking of paper shall comply with the provisions of GB/T10342 or the requirements of the order contract. 6.2 The paper shall be properly stored to prevent the influence of rain, snow and ground mixed air. 6.3 During transportation, clean transportation vehicles with canopies shall be used. It is strictly forbidden to drop from a height during unloading. 6.4 If the product deteriorates or suffers other losses due to storage and transportation that do not meet the requirements of this standard, the party responsible for the loss shall be responsible. Additional remarks:
This standard was proposed by the Paper Industry Department of the Ministry of Light Industry. This standard is under the jurisdiction of the National Paper Standardization Center. This standard was drafted by Shanghai Paper Company and Shanghai Kaiyuan Paper Mill. The main drafters of this standard are Zhang Hanzhong, Xu Yuezhen, Li Chunfu and Zhang Decheng. From the date of implementation of this standard, the former Light Industry Department standard QB739-1980 "Bobbin base paper" will be invalid. This standard adopts "OCT891-1975 "Textile bobbin and cone paper and paperboard".
