本文件旨在规定适用于AMS-7xxx系列规范要求的质量一致性测试（仅限于硬度、拉伸试验、压缩永久变形、比重和体积膨胀）的O形圈尺寸。此外，供应商和/或用户可自行决定和/或根据其采购文件，选择援引本规范进行采购，或出于AS568未涵盖的O形圈尺寸的其他目的。如果在任何AMS-7xxx规范中规定附加试验为质量一致性试验，则该规范还应规定附加试验所需的试验尺寸。 本文件不涉及AMS-7xxx系列规范要求的鉴定试验用O形圈尺寸，因为AMS-7xxx规范中已经规定了该尺寸。本文件仅涵盖测试类型所需的O形圈尺寸。这些O形圈尺寸包括但不限于AS568 xxx O形圈尺寸。其他测试细节，如ASTM或其他测试方法等，如特定的AMS-7xxx规范等，不在本规范的范围内，本规范不涉及。AS6837取代ARP3050。

The purpose of this document is to specify the O-ring sizes that are suitable for quality conformance testing (limited to hardness, tensile tests, compression set, specific gravity, and volume swell per ASTM D1414) required by AMS-7xxx series of specifications. In addition, suppliers and/or users, at their own discretion and/or according to their procurement documents, may choose to invoke this specification for procurement or other purposes for O-ring sizes that are not covered by AS568.If additional tests are specified as quality conformance tests in any AMS-7xxx specification, then that specification shall also specify the required test size for that additional test. This document does not address O-ring size for qualification testing required by AMS-7xxx series of specifications since that is already specified in the AMS-7xxx specification. This document only covers O-ring sizes required by test type. These O-ring sizes include, but are not limited to, AS568-xxx O-ring sizes. Other testing details such as ASTM or other test methods, etc. are covered elsewhere such as the specific AMS-7xxx specification, etc. and are beyond the scope of this specification and are not addressed in this specification.AS6837 supersedes ARP3050.
