Flow rate testing, How?

How can I check the flow rate of some injectors I have??

Basically it involves attaching the enjectors to a fuel rail, FPR and pump, just like in a car, turning everthing on with the injectors pointing into a cups/bottles or any other suitable containers and measuring the amount of fluid collected over set period of time.

any Idea what the set period of time could be?? I belive the injectors could be 440cc but im not 100% sure, I would like to test them just to make sure

440cc means 440ccs of fluid per minute (usualy measured at 3 bar of pressure), but you can run the test for let's say 30 seconds and multiple the amount of fluid by 2 to conver to cc/minute.

I've got a follow up question. What's the longest amount of time you can run an injector at 100% without damaging it? Or, is it neccessary to hook it to some circuitry which mimics the ecu providing a pulse train with fixed duty cycle preferably less then 85%?
