Packaging and Package Marking12.1 PackagingThe material shall be wound on a one-piece substantial core with inside diameter
16、as specified. Endsof rolls shall be protected with suitable caps or roll endprotectors to ensure against edge damage. The material shall bepacked in moisture-proof wrappers, boxes, or cartons soconstructed as to ensure acceptance by common or othercarriers for safe transportation at the lowest rate
17、to the point ofdelivery, unless otherwise specified in the contract or order.12.2 Package MarkingEach container shall be marked onthe side or on one end of the package, or on both the side andend, with the name and type of material, specification number,purchase order number, manufacturers name or t
18、rade mark, orboth, manufacturers roll number, lot number, and the date ofmanufacture. Each roll or pad shall be marked on one side withthe manufacturers name and lot number and the customerspurchase order number.13. Retest and Rejection13.1 If the results of any test do not conform to therequirement
19、s prescribed in this specification, at the option ofthe manufacturer that test shall be repeated on two additionalsets of specimens from the same batch or shipment, each ofwhich shall conform to the requirements specified. If either ofthese two additional sets of specimens fails, it is acceptable to
20、reject the material at the option of the purchaser.13.2 Notice of failure of material based on tests made inaccordance with this specification shall be reported to themanufacturer within three weeks from receipt of the materialby the purchaser. Any portion of an accepted shipment ofmaterial that is
21、subsequently shown not to have been inaccordance with this specification at the time of receipt it isacceptable to reject, provided the manufacturer is notifiedwithin 90 days from the date of receipt of the material by thepurchaser.14.
