GB/T 12604.10 — Non-destructive testing — Terminology — Part 10: Magnetic memory testing

📋 Scope / 适用范围 ai_extracted

This standard specifies the general requirements for the ultrasonic testing of wrought metals and their products using ultrasonic (longitudinal or shear wave) pulse-echo (immersion or contact) testing techniques, as well as the requirements for longitudinal wave testing and shear wave testing. This standard is applicable to the ultrasonic testing of forging blanks, forgings, rolled products, plates, extruded or rolled bars, profiles, and parts machined therefrom.

本标准规定了用超声(纵波或横波)脉冲反射(液浸或接触)检测技术检验变形金属及其制件的一般要求和纵波检验及横波检验要求。本标准适用于锻坯、锻件、轧制件、板材、挤压或轧制棒材、型材，以及由其经机加工制成零件的超声检验。

📝 Foreword / 前言 ai_extracted

This standard replaces GJB 1580-1993 "Ultrasonic Inspection Methods for Wrought Metals" and GJB 593.1-1988 "Specification for Quality Control of Nondestructive Testing - Ultrasonic Longitudinal and Shear Wave Inspection". Compared with GJB 1580-1993 and GJB 593.1-1988, the main differences of this standard are as follows: a) Inconsistent contents in the two standards have been unified, such as operating frequency, calibration cycle of standard test blocks, surface roughness of inspected parts, and scanning spacing; b) Requirements for flat-bottomed hole machining, probe frequency inspection, and immersion tank dimensions have been modified; c) Additional contents include methods for flat-bottomed hole quality inspection, requirements for manufacturing special test blocks, and methods and requirements for adjusting the incident angle of the sound beam in immersion testing. Appendices A, C, D, E, F, H, and G of this standard are normative appendices, while Appendix B is an informative appendix. This standard was proposed by China Aviation Industry Corporation I. This standard is under the jurisdiction of China Aero-Polytechnology Establishment and Beijing Institute of Aeronautical Materials. Drafting organizations of this standard: Beijing Institute of Aeronautical Materials of China Aviation Industry Corporation I, Aerospace 703 Institute, and Aviation 430 Factory. Main drafters of this standard: Liang Jing, Shi Yiwei, He Shuangqi, Li Ze. GJB 1580-1993 "Ultrasonic Inspection Methods for Wrought Metals" was first published in March 1993, and GJB 593.1-1988 "Specification for Quality Control of Nondestructive Testing - Ultrasonic Longitudinal and Shear Wave Inspection" was first published in August 1988. GJB 1580A-2004

本标准代替GJB 1580－1993《变形金属超声波检验方法》和GJB 593.1－1988《无损检测质量控制规范超声纵波和横波检验》。本标准与GJB 1580－1993 及GJB 593.1－1988 相比，主要差别如下： a) 对两份标准中不一致的内容进行了统一，如工作频率、标准试块的检定周期、受检件表面粗糙度和扫查间距等； b) 对平底孔加工要求、探头频率的检验要求、液浸槽尺寸的要求等内容进行了修改； c) 增加了平底孔质量检验方法、专用试块的制作要求、液浸法检验声束入射角的调整方法和要求等内容。本标准的附录A、附录C、附录D、附录E、附录F、附录H、附录G 为规范性附录，附录B 为资料性附录。本标准由中国航空工业第一集团公司提出。本标准由中国航空综合技术研究所、北京航空材料研究院归口。本标准起草单位：中国航空工业第一集团公司北京航空材料研究院、航天703 所、航空430 厂。本标准主要起草人：梁菁、史亦韦、何双起、李泽。 GJB 1580－1993《变形金属超声波检验方法》于1993 年3 月首次发布，GJB 593.1－1988《无损检测质量控制规范超声纵波和横波检验》于1988 年8 月首次发布。 GJB 1580A－2004
