Potential failure analysis
1.When the magnet assembly after magnetic circuit, the temperature in the positive and negative sixty degrees centigrade,and under the condition of no magnetic field around,
magnet magnetic pass rate less than or equal to 0.05%;
2, Time stability
2.1.At room temperature for long-term storage (there is no magnetic field) cases, magnetic drop 1 to 2%;
2.2.When magnet is open using (cylindrical products), magnetic decline and the product of the length to diameter ratio;
3.Cylindrical magnet temperature stability
3.1. Used at 100°C to negative 200 °C ,the magnet of the residual temperature coefficient for negative 0.022 to negative 0.016%;
3.2. Used at negative 190°C to negative 200 °C ,the magnet of the residual temperature coefficient for negative 0.007 to negative 0.022%;
