Foreword
This Standard replaces JB/T 8290-1998 "Magnetic Particle Flaw Detectors".
Compared with JB/T 8290-1998, The main changes of this Standard are as follows.
- The technical requirements and inspection methods for tangential magnetic field
strength of magnetic particle flaw detectors were added (4.3.3 and 6.6 of this
edition);
- The technical requirements and inspection methods for visible light illumination
of magnetic particle flaw detectors were added (4.6 and 6.9.2 of this edition);
- The technical requirements and inspection methods for bypass current of
magnetic particle flaw detectors were added (4.3.4 and 6.5 of this edition);
- The technical requirements and inspection methods for safety voltage of
magnetic particle flaw detectors were added (4.8.2.4 and 6.7 of this edition);
- The technical requirements and inspection methods for continuity of protective
grounding circuit of magnetic particle flaw detectors were added (4.8.2.1 and
6.11 of this edition);
- Quality assurance of magnetic particle flaw detectors was added (Chapter 5 of
this edition);
- Chapters 3 and 4 of 1998-edition were deleted.
The national standards of technical requirements and inspection methods that are
relevant to this Standard are as follows.
