3.4 ​​Appearance
3.4.1 The surface of the paper should be flat and the fiber structure should be uniform. There should be no folds, wrinkles, hard blocks, holes, streaks, light spots, cracks, spots and other paper defects that affect the use.
3.4.2 The dry paper should not have broken ends. It can be printed on one side or both sides and should be rolled on a dry and hard core tube. 3.4.3 The printing ink color is green. The printed part should be correct and clear, and the ink color should be consistent. There should be no color spots and broken lines or ink marks that affect the reading.
4 Test method
4.1 Main technical indicators of base paper
Quantitative determination shall be made in accordance with GB/T451 "Determination of size, skewness, quantitative determination, thickness and tightness of paper and paperboard". a.
Sizing degree shall be determined in accordance with GB/T460 "Determination of sizing degree of paper and paperboard (ink streaking method)". b.
c. Dust degree shall be determined in accordance with GB/T1541 "Determination of dust degree of paper and paperboard (area method)". 4.2 Size tolerance
This test shall be carried out under the condition of ambient temperature of (20±2)℃ and relative humidity of 63%～67%. Before the test, the dry paper strip shall be placed under the above conditions for more than 12 hours to stabilize it, and then visually inspected with a metal ruler. The parallelism between the zero scale line and the edge of the paper should be measured within any 500mm length of the paper strip. 4.3 The scale line width
should be checked on a reading magnifying glass with a magnification of 10 times. During the inspection, one A and one C line should be selected at random, and several points on the entire length should be measured. At the same time, it should be compared with several points on any other A and C lines to find out the difference in line width. 4.4 Appearance
Inspect by visual inspection.
5 Inspection rules bzxZ.net
5.1 The quantity delivered at one time is considered as a batch. The unit of delivery test is "roll". 5.2 Delivery test sampling shall be carried out in accordance with the provisions of GB/T2828 "Batch-by-batch inspection counting sampling procedures and sampling tables (applicable to continuous batch inspection)".
5.3 Samples taken from sample units and processed in accordance with GB/T450 "Methods for taking average samples of paper and paperboard and processing samples before inspection" KAca
QB/T3510-1999
Regulations" (2) The average sample of each packaging unit is taken. 5.4 The acceptance test inspection level is S-3, the sampling plan is a normal sampling, and the qualified quality level (AQL) is 4.0%. 5.5 Batches that fail the inspection can be submitted for inspection again. The inspection level of the resubmission is 1. If it fails again, it will be judged as an unqualified batch.
6 Marking, packaging, transportation, storage
Each roll of paper should be packed in a sealed plastic bag. 6.1
6.2 The product should be packed in a carton with a layer of moisture-proof paper on all sides. The upper and lower covers of the carton should be sealed with tape, and then fastened with two plastic tapes on the outside.
6.3 Each roll of paper should have product name, product number, measurement range, factory name (factory logo) and other logos. 6.4 There should be an A on the side of the carton. Size mark Label, indicating: a. Product name; b. Product number, c. Measuring range; d. Quantity inside; e. Carton size; f. Gross weight of carton; name and work number of packer; h. Packing date; i. "Placement direction" and "Moisture-proof" etc. 6.5 The gross weight of each carton shall not exceed 15kg. 6.6 During transportation During the process, the products shall not be exposed to rain, snow or liquid substances and mechanical damage, and shall be stacked in the direction of the cartons. 6.7 During loading and unloading, cartons shall not be dragged or dropped from a height. 6.8 During storage, they shall be properly kept and stored in a dry and insect-free room.
