Performance
The thermal-links must comply with the following test items and any other applicable requirements.
-1. Appearance and Dimension check
Test conditions: Visual, Micrometer or Caliper
Specific: The display should be legible with no remarkable fault, and the size should be within the specificed dimcnsions.
-2.Resistance test
Test conditions: The D.C. resistance be mcasured by putting the thermal-links body between less than 20mm by four terminal method.
-3. Functioning temperature test
Test conditions: The thermal-links soaking in oil bath which rise temperature at 0.5~ l.0C/min, and mcasure the oil temperaturc at functioning. Mcasurcment beginning temperature Tf -20°C,and the detection current are assumed to be less than 10mA.
Specific: Functioning within at +0°C,-79C of rated functioning temperature.
-4. Insulation resistance test
Test conditions: (a) Beforc functioning test .between case and lead wires
(b) After functioning test●between case and lead wires between lead wires
Specific: D.C. 100V,more than 1000MQ
-5. Diclectric withstand test
Test conditions: (a) Before functioning test *bctween case and lead wires
(b) After functioning test●between case and lead wires
(c) Afler functioning test● between lead wires
Specific: (a)(b) Apply D.C.1 100V continuity endure for I minutc. (Detection current 0.5mA)
(c) Apply D.C. 100V continuity endure for I minute. (Detection current 0.5mA)
-6.Humidity test
Test conditions: Measure the functioning temperature after left for 500 hours in the following temperature conditions.T6D [60C 95%RH]
Specific: Functioning within at +0°C,-109C of rated functioning tempcrature.
-7. Heat shock test
Test conditions: Measure the functioning temperature after left for per 30 minutes with 200 cycles in the following temperature conditions.T6D-L [-40°C-80°C]
Specific: Functioning within at +0°C,-10°C of rated functioning temperature.
