Muffler Testing Suggestions?
(OP)
I need to test a muffler -
The performance requirements are as follows:
"Muffler shall be capable of quietly discharging air at a flow rate of 300 to 450 SCFM with a static pressure of 30 to 60 PSIG."
We wouldn't even know where to begin with this in my shop.
Can anyone recommend a lead on where to get this done?
thanks,
r

There are lots of places capable of performing this work, but I have personal experience with Intertek and have had good results.
Just be aware, Intertek is a very prim and proper testing lab. Therefore they will test word for word what is in your test plan. This is a good thing in my opinion, just make sure your requirements are clear before the testing starts.

Thanks for the tip.
And as for I wouldn't have it any other way!

If it's at all to do with certification (power and/or noise) then one would normally also run a conditioning exercise on the muffler to ensure that it's effectiveness is stabilised. i.e. the performance figures you quoted aren't changing.

I know it's a silly requirement, but the customer gets what the customer wants.

I believe you are correct. If I were specifying a muffler test, I would spec a mass flow rate vs. delta P, not volume flow.
