Sampling rate
Inspect once for every four axes
Inspect once for each batch
Inspect once for each batch
Inspect each axis
Inspect at least once for each batch
The receiving unit generally accepts based on the certificate of conformity.
If the receiving unit conducts sampling inspection, the acceptance batch is based on the axis number, and one outer box is selected for each axis number or emulsion number, and at least 3 rolls are taken from each box for inspection
The inspection shall be carried out according to the items and methods specified in this standard. 1IG / T 2696 -- 95
If any of the indicators in the registration inspection are unqualified. If the re-inspection is qualified, the film of this batch shall be accepted; if the re-inspection is still unqualified, the product of this batch does not conform to this standard. ≤Quality Assurance Clauses
Films that have been accepted by the using department may be replaced or returned according to the actual consumption of films within the warranty period under the transportation, storage and use conditions specified in this standard if there are indeed quality problems with the films after verification. 7 Packaging and Marking
