I am looking for a PDF copy of DW-143 for information on the pressure testing of Ventilation ducting. I have the DW-144 document and it is useful to an extent, but i need the 143 document as soon as i can get it.
Does anybody have any idea where i can get it, or if anyone has it, could they drop me a PM. I am in a bit of a fix over this, so i would really appreciate it if anyone can help me.

Do you lads work for a company?

Most of them have online sources of info for getting standards and what not

I work for myself with another guy but the ducting trade is quite quiet at the moment other wise i would just buy a copy but @ £60 but thought i would try free methods first!

I forgot i had started this thread. I got the info i needed from somebody on PM.
I don't work for a company with access to it as I am doing duct pressure testing on my own.

Chrisby27 - If you are still lloking for 144 i have it and i can give it to u. Let me know.
