Designed to determine the quality of the magnetic suspension, modes of magnetization and magnetic particle technology for the appropriate level of sensitivity.
Reference samples correspond to the requirements of ГОСТ 21105-87 and procedure ПНАЭ Г -7-015-89
Reference samples have an artificial crack with a width of disclosure in accordance with required level of sensitivity.
| The size of the crack, mm | |||
| Nominal sensitivity | Width of disclosure | Length | Depth |
| А | 0,002 | no less than 20 | 0,25 - 0,3 |
| Б | 0,010 | no less than 20 | 0,25 - 0,3 |
| В | 0,25 | no less than 20 | 0,25 - 0,3 |
Each sample has a passport with a photograph of the crack and its description, appropriate parameters of control, and measurement certificate.The set includes: working, control and arbitration samples.
