6 Test method
6.1 Specimen pretreatment
Specimens in GB/T6529 standard atmospheric conditions for at least 1h after the test.
6.2 Monofilament diameter tolerance and coefficient of variation
6.2.1 You use a micrometer caliper with an accuracy of 0.001 mm, measuring a point every 1 m, measuring 20 points, record the maximum and minimum values, and calculate the deviation from the nominal value.
6.2.2 monofilament diameter CV value according to the formula (1) and formula (2) calculation.
7 inspection rules
7.1 Batch regulations
The same species, the same batch number of products as a batch.
7.2 Sampling
According to GB/T 6502 implementation.
7.3 Determination of intrinsic quality
Intrinsic quality all meet the requirements of 5.1, the intrinsic quality of qualified. If there are unqualified items, in accordance with 7.2 resampling, the unqualified items for retesting. If the re-inspection is qualified, the batch of products is considered to be qualified; if still unqualified, the batch of products is not qualified.
7.4 Determination of appearance quality
Appearance quality all meet the requirements of 5.2, the appearance quality qualified. If there is not loose items, in accordance with 7.2 resampling, the unqualified items for retesting. If the re-inspection qualified, the batch of products considered qualified appearance quality; such as must be qualified, the batch of products failed appearance quality.
7.5 Judgment of the results
7.3 and 7.4 judgment are qualified, then the batch of products qualified.
8 Logo, packaging, transportation and storage
8.1 Marking
8.1.1 Each batch of qualified spool should be labeled, and the label should indicate the product model and production date.
8.1.2 Packaging carton should be trademarked, the name and address of the manufacturer, product model, production date, product implementation standard number.
8.2 Packaging
Product packaging should be marked not to throw and more than 8 layers of overlap, as well as moisture, sunlight, anti-corrosion signs, packaging, storage and transportation signs should be consistent with GB/T 191. winding spool can be referred to Appendix A, each axis of monofilament application of plastic film (preferably dark) wrapped and then packaged in a carton, bagging requirements according to the purchase of the two sides to confirm.
