what is IS 1548 specification?

I am supposing that you are looking for the specification of ISO 1548:\n\nAbstract.\nIncludes the requirements for these components for use in aircraft electrical systems having voltage and frequency characteristics conforming to ISO/R 222, at any ambient temperature from -65 to +85 degrees centigrade, and all altitudes from 0 to 24 000 m. Gives terminology, requirements for dimensions, current, voltage and breaking-capacity ratings, time/current characteristics and tests.\n\nYou can buy the whole text on the source site.

They don't say what they are because you are suppose to get a copy of B31.9 and follow its requirements. \n\nB31.9 can change from time to time and this way the specification is always current. If the specification spelled out B31.9 and then quoted the requirements and they had changed in the mean time there would be a conflict.\n\nI have written many specifications for piping and this is the only way to be sure B31.9 or other industry standards are met.

1.0 Ton = 12 MBH\n\nI would get a confirmation on this though.

contact a supplier, they will give you all the specs you need.\nno one is going to type out 4 pages of stuff here for you.\nFittings is not a very specific question.
