Although it is smaller, each product is subject to strict factory inspection before leaving the factory, including appearance, size, static action temperature and crushing load test.
During the static action temperature test, the test ambient temperature is (20 ± 5) ℃, and the test is carried out in liquid bath. Water bath (distilled water is preferred) shall be adopted for glass bulbs with nominal operating temperature not higher than 79 ℃, and oil bath (oil products suitable for nominal operating temperature) shall be adopted for glass bulbs with nominal operating temperature higher than 79 ℃. The temperature of the test liquid bath shall be uniform, the temperature deviation in the test area shall not exceed 0.5 ℃, and the temperature measurement accuracy shall not be less than ± 0.1 ℃.
Place the glass bulb sample vertically in the liquid bath. The distance between the center of the glass bulb and the liquid level is not less than (40 ± 5) mm. Raise the temperature from room temperature to (20 ± 2) ℃ lower than the nominal operating temperature at a heating rate of not more than 20 ℃ / min. after holding for 10 minutes, raise the temperature at a rate of 0.4 ℃ / min ~ 0.6 ℃ / min until all the samples are broken. Record the operating temperature of each sample, Judge whether the test results exceed the following temperature range:
X ±(0.035X + 0.62)
X — Nominal operating temperature, unit: Celsius (℃).
