The printed text on 3mm sprinkler bulb is “ZJCY”. Compared with 5mm sprinkler bulb, its response will be faster, RTI ≤ 50, where RTI is a coefficient measured under standard conditions to measure the sensitivity of sprinkler bulb. Expressions:RTI= τ u ½

Where: RTI – response time coefficient, unit (m * s) ½;
             τ- Response time constant, in s;
             u – gas flow rate, unit: m / s
The quality of the sprinkler bulb fully complies with the Chinese national standard GB18428-2010. The diameter of the sprinkler bulb is 3mm, and the deviation from the nominal diameter will not exceed ± 0.1mm; Its length is 23mm and the deviation from the nominal length will not exceed 0.5mm.
The average crushing load of the sprinkler bulb is 3600n. During the test, the sprinkler bulb will be fixed between the supporting elements in an appropriate way, and the supporting elements are made of steel. The Rockwell hardness is (44 ± 6) HRC, which meets the corresponding service requirements. Then, apply a uniform load along the axis of the sprinkler bulb until the sprinkler bulb bursts, and the rate of load increase is (250 ± 25) N / s. The maximum deviation of the equipment used to measure the crushing load shall not exceed ± 1% of the measured value. Use multiple groups of measured data to calculate the average value and standard deviation of the crushing load and judge whether the results meet the specified standards.
