Also under natural light, select the present minister that can be swallowed, and conduct inspection by sensory determination, and the inspection rules are as follows.1 batch
with a variety of raw materials, one production process, one product of one variety of materials, one inspection package 7.2 Factory inspection
7.2.1 Products should be inspected, and qualified products should have qualified sources. 7.2.2 Inspection items
other requirements, color fastness (ten rub, surface rub), flame retardancy. 7.2.2.1 Sensory requirements
Select 6.2 color fastness (sheets) for inspection: 7.2.2.2 Color fastness, flame retardancy
Randomly pick 3 sheets (sheets) from all the products in the sensory inspection and inspect them according to the provisions of 6.1.4 and 6.1.10. 7.2.3 Qualification judgment
All the inspections shall comply with the provisions of 4.2: Friction color: 3 pieces (pieces) of the rubbing, astringency and compatibility inspections shall all be qualified, and the batch of products shall be judged to be qualified. Moisture fastness: If the test results are unqualified in the test of friction, wet rubbing and cathodic fastness, the relevant inspection shall be carried out, and if all the re-inspection items are qualified, the batch of products shall be judged to be qualified. 7.3 Type inspection
7.3.1 In the following cases: - Type inspection shall be carried out. a) There are five changes in materials, processes and chemical materials: a) The production shall be suspended for a long time (eight days) and the national quality supervision and inspection agencies at all levels shall propose to conduct type inspection when the production is resumed: and the production shall be carried out at least once a year, and 3 pieces (pieces) shall be randomly batched and controlled from the qualified products. 7.3.3 Qualified judgment
7.3.3.1 Principles for judging single sheet
QB/T2703-2C05
If any of the tearing, contact rate, time-limited degree, light absorption, aging resistance, abrasion resistance, layer standing height, magnetic resistance, fogging value, odor, prohibited ammonia dyes, free formaldehyde is not present, or there are cracks, cracks and other factors that affect the use function, the sheet is judged to be unqualified. , if three of the other items in the technical requirements are unqualified, the sheet (piece) is judged to be unqualified. 7.3.3.2 Principles for the whole batch evaluation
) The three indicators of chemical value, ignition resistance and separation resistance are tested in batches, and the following rules are set: 3 sheets (pieces) are tested individually (two samples of chemical value are taken from 1 sheet) for inspection. If one of the indicators in the table is unqualified, the batch of products is unqualified. ) The remaining indicators are first tested and judged by single sheet (upper sheet), and the batch rate is determined. If 3 samples (pieces) are qualified, and all the three indicators of chemical value, ignition resistance and separation resistance are all qualified, the batch of products is judged to be qualified. If one or more sheets (pieces) are unqualified, then 6 sheets (pieces) will be selected for retrograde inspection, which can be repeated. If two test standards, flammability and resistance, are required, 4, 3 and 3 samples will be taken respectively (1 for a single sheet). If one of the indicators is not qualified, the batch of products is unqualified: the rest of the indicators are not allowed to be determined, and the whole batch will be determined. If 6 samples (pieces) are qualified, and one of the indicators, atomization value, flammability and resistance are all qualified, then the batch of products is judged to be qualified. In the whole batch determination, the atomization value, flammability and resistance indicators are not determined for a single sheet (piece). Multiple markings, packaging, transportation, purchase and storage shall comply with the provisions of GB4694.
