Such as cap open torque force, thermal stability, resistance to drop performance, leakage and sealing performance. Which
sealed performance and cap open, tightening torque assessment of
plastic anti-theft cap sealing performance to solve an effective way. Depending on the use of the cap, there are different provisions for the measurement of the gas cap and the gas cap. Seal
cover (without gas cover) The cap should be cut out of the anti-theft
ring (bar) for not less than 1.2NM rated torque seal, with a sealed
tester [1] test, pressurized to 200kPa, underwater Pressure
for 1 minute, observe whether the leak or tripping; breathable cover
(including gas cover) is pressurized to 690kPa, keep the pressure in
water for 1 minute to observe whether the leak, then the pressure
increased to 1207kPa, keep the pressure for 1 minute, Observe whether the plastic cover is tripped.
