6.
Operate pump lever as necessary to hold pressure at a level about 290 psi (1999 kPa) below opening pressure noted in
above.
7.
No drops must fall from nozzle tip for a period of 10 seconds, while maintaining pressure specified above. If drops do
appear within 10 seconds, replace injector.
NOTE
For chatter test, use same test set up for opening pressure test.
Do not evaluate used nozzles at lower pumping rates. A used nozzle is serviceable if it passes the leakage
test, chatters audibly at higher pumping rates and uniformly atomizes fuel.
8.
Operate pump lever at a rate that causes nozzle to chatter softly while discharging fuel in a broad and finely atomized
pattern. If conditions of prior note are not met, replace nozzle.
