the NPFA 96 code use to say, the entire system should be cleaned to bare metal, now it states that they should be cleaned to .002 inches?
how big is .002 any way? i mean in relative terms? Is it what half the width or a piece of paper? Or a quarter thickness of a hair?
Whats the proper way to check & insure you have cleaned a system to .002? Because .002 aint much i mean could you really even see it, you would think most grease at this thickness would be transparent. If so then would it be bare metal? knowing you can't see it but still tier. How would the invoice read. Entire Exhaust system cleaned to .002 inches.
Would the customer ask how do you know it's .002 inches, what would one have to say,...... well i sprayed it...a lot.. and ..... it ....uh...came clean....so it's....yah.....002..
kind of a weird number wonder where the # came from. maybe some fancy research?
makes me wonder why they took out the bare metal part,,hu,,,you think it could be some excuse for some to leave grease behind?
