SCOPE:1.1 Form: This specification covers a copper-zinc alloy (brass) in the form of laminated sheet.1.2 Application:
6、 This sheet has been used typically for shims in which thickness is adjusted by removal of laminations as required, but usage is not limited to such applications.2. APPLICABLE DOCUMENTS: The issue of the following documents in effect on the date of the purchase order forms a part of this specificati
7、on to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been canceled and no superseding document has been specified, the last published issue of that document shall apply.2.1 ASTM

24、wing the results of tests on each lot to determine conformance to the technical requirements. This report shall include the purchase order number, lot number, AMS 4508H, shim stock thickness, foil thickness, percentage of total thickness which is laminated, size, and quantity.4.5 Resampling and Rete
25、sting: If any specimen used in the above tests fails to meet the specified requirements, disposition of the sheet may be based on the results of testing three additional specimens for each original nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cau
26、se for rejection of the sheet represented. Results of all tests shall be reported.5. PREPARATION FOR DELIVERY: 5.1 Identification: Each sheet shall be legibly marked near one end with AMS 4508H, manufacturers identification, nominal thickness, thickness of each lamination, and percentage of total th
27、ickness which is laminated. The characters shall be applied using a suitable marking fluid removable in hot alkaline cleaning solution without rubbing. The markings shall have no deleterious effect on the sheet or its performance and shall be sufficiently stable to withstand normal handling.5.2 Pack
28、aging: Sheet shall be prepared for shipment in accordance with commercial practice in compliance with applicable rules and regulations pertaining to the handling, packaging, and transportation of the sheet to ensure carrier acceptance and safe delivery. 6.
