Would You Consider a Performance Test Of The Trigger Spray?
-
Functional testing should be a major part of the overall sample testing. The score of the functional test largely determines whether the sample trigger sprayer can deliver good product performance and user experience.
Primetime:
Fill the bottle with liquid and count how many squeezes are used until the first shot comes out. This test somehow reflects the tightness of the piston and cylinder.
Output:
Perform at least 30 squeezes to squirt the liquid into a large opening measuring cup. The total volume of the fluid is then measured and divided by the corresponding number of extrusions to get the output.
Jet degree:
Although a certain spray angle is required, do this test. Place the nozzle end of the trigger sprayer at a certain distance (usually 20cm) from the target surface, then pull the trigger and measure the diameter of the wetted area on the surface. This should be performed indoors and sprayed from top to bottom to minimize the effects of drafts and gravity.
Leak test:
Press the trigger at least 30 times, check the nozzle end and piston for leaks, and test the spray and flow pattern.
Foaming test:
If the trigger spray pump has a foam nozzle, a foam test should be performed to check the adhesion time of the foam on the target surface.
ventilation:
Row holes are usually seen under the gasket seal. The vent prevents the bottle from collapsing after multiple squeezes. So don't forget to check if your test bottle collapses after multiple squeezes.
Fatigue test:
This is probably the hardest part of client-side testing, as it can require thousands of squeezes that a human hand can't handle. If not applicable to you, please ask the supplier to perform this test and submit a test report. The purpose of this test is to ensure that trigger sprayers can empty chemicals flawlessly, especially those paired with bulk reservoirs. Vendors usually have custom machines to operate this test.
