ISO 9934-3:2015描述了三种磁粉检测设备: -便携式或可移动设备； -固定装置； -用于连续测试部件的专用测试系统，包括一系列按顺序放置的加工站，以形成一条加工线。 还描述了磁化、退磁、照明、测量和监测设备。 ISO 9934的本部分规定了设备供应商提供的性能、最低应用要求和测量某些参数的方法。 在适当的情况下，还规定了测量和校准要求以及在用检查。

ISO 9934-3:2015 describes three types of equipment for magnetic particle testing: - portable or transportable equipment; - fixed installations; - specialized testing systems for testing components on a continuous basis, comprising a series of processing stations placed in sequence to form a process line. Equipment for magnetizing, demagnetizing, illumination, measurement, and monitoring are also described. This part of ISO 9934 specifies the properties to be provided by the equipment supplier, minimum requirements for application and the method of measuring certain parameters. Where appropriate, measuring and calibration requirements and in-service checks are also specified.
