摘要

1.1 This practice covers the standards and procedures for the pulse-echo ultrasonic examination of heat-treated carbon, low-alloy, and martensitic stainless steel castings.1.2 This practice is to be used whenever the inquiry, contract, order, or specification states that castings are to be subjected to ultrasonic examination in accordance with Practice A609/A 609M.1.3 This practice contains two procedures. Procedure A is the original A609/A609M practice and requires calibration using a series of test blocks containing flat bottomed holes. It also provides supplementary requirements for angle beam testing. Procedure B requires calibration using a back wall reflection from a series of solid calibration blocks.Note1—Ultrasonic examination and radiography are not directly comparable. This examination technique is intended to complement GuideE94in the detection of discontinuities.1.4 Supplementary requirements of an optional nature are provided for use at the option of the purchaser. The supplementary requirements shall apply only when specified individually by the purchaser in the purchase order or contract.1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.5.1 Within the text, the SI units are shown in brackets.1.5.2 This practice is expressed in both inch-pound units and SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply.1.6This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.1本规程涵盖了热处理碳、低合金和马氏体不锈钢铸件的脉冲回波超声波检查标准和程序。1.2当询价单、合同、订单或规范规定铸件应根据规程A609/A 609M进行超声波检查时，应使用本规程。1.3本规程包含两个程序。程序A是最初的A609/A609M规程，需要使用一系列包含平底孔的试块进行校准。它还提供了角波束测试的补充要求。程序B要求使用一系列固体校准试块的后壁反射进行校准。笔记1-超声波检查和射线照相不能直接比较。该检查技术旨在补充指南E94在检测不连续性时。1.4提供了可选性质的补充要求，供买方选择使用。补充要求仅适用于买方在采购订单或合同中单独规定的情况。1.5以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。1.5.1在本文中，国际单位制显示在括号中。1.5.2本惯例以英寸-磅单位和国际单位制表示；但是，除非采购订单或合同规定了适用的M规格名称（国际单位制），否则英寸-磅单位应适用。1.6本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。展开▼
