第一机械工业部于1964年4月在苏州召开了一次一机部系统的全国无损探伤会议,制订了“无损探伤应用条例”、“焊缝射线检验质量标准(草案)”、“焊缝射线检验质量标准制定说明”、“焊缝射线照相检验技术条例”、“超声纵波探伤标准试块技术条例”、“磁粉探伤技术条例”等文件,其中“焊缝射线检验质量标准”是草案,供讨论征求意见用,其余四个都是试行条例,自1964年9月起在该部范围内试行。我们认为这些文件在促进我国无损探伤工作和提高技术水平方面有普遍性的指导意义。因此,征得一机部同意,将这些文件予以转载,以供大家参考和应用。今后如对这些文件有修改意见,可通过各部技术司向一机部技术司反映。
In April 1964, the First Ministry of Machinery Industry held a conference of non-destructive flaw detection of one machine department system in Suzhou, and formulated “Application Regulations of Non-destructive Flaw Detection” and “Quality Standard of Weld Ray Inspection (Draft) ”Weld ray inspection quality standards for the development of “, ”weld radiographic inspection technical regulations “, ”ultrasonic longitudinal wave inspection standard test block “, ”magnetic particle inspection technical regulations " and other documents, The quality standard for weld ray inspection is a draft for discussion and solicitation of opinions. The remaining four are all tentative regulations, which have been piloted within the department since September 1964. We think these documents have a general guiding significance in promoting non-destructive testing in our country and in improving the technical level. Therefore, with the consent of a machine department, these documents should be reproduced for your reference and application. In the future, if there is any amendment to these documents, they may be reflected by the Technical Division of each department to the Technical Division of a machine department.
