5、 AMS2658B Hardness and Conductivity Inspection of Wrought Aluminum Alloy Parts RATIONALEAMS2658C revises test locations (4.4) and hardness and conductivity values (Tables 1, 2) and is a Five Year Review and update of this specification. 1. SCOPE 1.1 Purpose This specification establishes hardness an

6、d electrical conductivity acceptance criteria of finished or semi-finished parts of wrought aluminum alloys. 1.2 Application This specification has been used typically for nondestructive testing of wrought aluminum alloy parts to aid in determining correctness of alloy, temper, and/or heat treatment

7、, 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 specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific

8、document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 ASTM Publications Available from ASTM International, 100 Barr Drive, P.O.

TECHNICAL REQUIREMENTS 3.1 Equipment The equipment used for hardness

12、and electrical conductivity testing shall meet the requirements of ASTM E 10, ASTM E 18, ASTM E 1004, or MIL-STD-1537, as applicable. 3.1.1 Verification The hardness test equipment when in use shall be checked against test blocks at least once per day to ensure accurate and repeatable results. The c

13、onductivity test equipment shall require a periodic standardization every hour of continuous operation. Equipment which does not provide accurate or repeatable results shall be corrected and recalibrated. 3.2 Procedure 3.2.1 Hardness Shall be determined in accordance with ASTM E 10 for Brinell hardn

14、ess and ASTM E 18 for Rockwell hardness. 3.2.2 Electrical Conductivity Shall be determined in accordance with ASTM E 1004 or MIL-STD-1537. 3.3 Properties Parts shall conform to the hardness and electrical conductivity values in Table 1 for bare alloys and Table 2 for clad alloys after heat treatment

15、 or annealing in accordance with the applicable specification. Alloys/tempers not contained herein shall be referred to the cognizant engineering organization. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The inspection source shall be responsible for the performance of all requ

16、ired tests. Purchaser reserves the right to perform any confirmatory testing deemed necessary to ensure that hardness and conductivity conform to specified requirements.4.2 Classification of Tests Not applicable. 4.3 Sampling and Testing Shall be in accordance with the applicable heat treatment spec

17、ification or as agreed upon by purchaser and processing vendor.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-,-SAE AMS2658C Page 3 of 84.4 Test Locations Shall be in accordance with the applicable dr

18、awing, specification or contract. 4.4.1 If test locations are not specified, the following shall be considered acceptable. 4.4.1.1 Conductivity testing shall be performed in accordance with the applicable heat treat document and at sufficient locations on the surface to ensure that the entire part m

19、eets the requirements of Tables 1 and 2. At a minimum the testing shall be performed as follows: A part with any dimension exceeding twelve inches shall be tested in more than one location. When more than one location is tested, each part shall be tested at a location near its center and at its dime

20、nsional extremes. Long, thin parts, such as extruded shapes or sheet metal parts shall be tested at both ends, and near the center. Parts shall be tested in both the nominally thinnest and thickest areas, when possible. Large sheets shall be tested in several locations in order to determine that the

21、 entire part meets the requirements of Tables 1 or 2. 4.4.1.2 Hardness testing shall be performed in accordance with the applicable heat treat document and at sufficient locations on the surface to ensure that the entire part meets the requirements of Tables 1 and 2. When tested at the thickest acce

22、ssible section, one hardness test per part is normally adequate to determine part acceptability. When less than 100% hardness testing is performed, the sample tested shall include those parts within the lot tested with the highest and lowest conductivity values.4.5 ReportsThe inspection source shall

23、 furnish with each shipment a report showing the actual minimum and maximum values obtained. This report shall include the purchase order number, AMS2658C, heat treatment specification number, part number, and quantity. 5. PREPARATION FOR DELIVERY Not applicable. 6. ACKNOWLEDGMENT A vendor shall men

24、tion this specification number and its revision letter in all quotations and when acknowledging purchase orders. 7. REJECTIONS Parts not inspected in accordance with this specification or not conforming to the specified hardness and conductivity requirements, or to modifications authorized by purcha

25、ser, will be subject to rejection. 7.1 Nonconforming Parts Parts failing to meet the hardness or electrical conductivity acceptance values specified herein shall be either reprocessed in accordance with the limits of the applicable heat treatment specification or referred to the cognizant quality as

26、surance organization for additional testing or evaluation. 8.
