dis 158dis 15848-1 & -2 for fugitive emissions testing of valves
dis 158dis 15848-1 & -2 for fugitive emissions testing of valves
dear all,
iso 15848-1fff"> and iso 15848-2fff"> have been recently promoted from the "committee draft" (cd) to the "draft international standard" (dis) status and, although still under development and at an inquiry stage ("40.60 - voting summary dispatched"), they are now available for public purchase (with a price of 64 chf each).
and finally, do you think it is worth buying the standard drafts? will this long work (started in 1997, at least) reach a world-wide accepted result?
many thanks in advance, 'ngl
48-1 -2 for fugitive emissions testing of valves
