1 标准制订的由来 漏磁探伤试验装置主要广泛应用于钢棒、钢管等质量保证领域。最近,这些装置的性能也已显著提高,据征询调查(1989年实施)的结果表明,日本拥有漏磁探伤试验装置约50～60台,由于漏磁探伤试验装置应用广泛,且使用者都是自行保养管理,这就迫切需要制订标准,使各自拥有的漏磁探伤试验装置,能按标准化方法进行性能测试,并按标准化方式表示测试的结果。 因此,NDI 312小委员会于1988年1月至1990年1月对本标准草案进行了探讨,1990年6月至1991年6月,由NDIS原草案制订探讨委员会重新探讨,并制订了本标准。 不存在与本标准相对应的国际标准。
The origin of a standard developed Magnetic flux leakage testing device is widely used in steel bars, steel pipes and other quality assurance areas. Recently, the performance of these devices has also been significantly improved. According to the results of the consultation survey (conducted in 1989), Japan has about 50 to 60 magnetic flux leakage testing devices. Since the magnetic flux leakage testing device is widely used and the users are all Self-maintenance management, which urgently need to develop standards so that each has a magnetic flux leakage testing device, according to a standardized method for performance testing, and standardized test results. Therefore, NDI 312 Subcommittee conducted a study on this draft standard from January 1988 to January 1990 and from June 1990 to June 1991, the NDIS original drafting Exploratory Committee revisited and formulated this standard. There is no international standard corresponding to this standard.
