The industry's comprehensive Specification for the manufacture and installation of sheet metal ductwork
DW/144 is the Standard Specification for ductwork manufacture and installation and is aligned to all current BS, BS EN ISO and other standards and regulations. It defines specifications for sheet metal ductwork for low, medium and high pressure/velocity air systems and covers ductwork application, materials, classification and air leakage. It highlights the technical information to be provided by system designers to ductwork contractors and looks in detail at rectangular, circular, and flat oval ductwork. It also contains updated information on hangers and supports, smoke and fire dampers, external ductwork, internal duct linings, thermal insulation, air terminal units, with many clear reference tables.

Show Replies (1)Section 7.5 states that there is a "minimum are to be tested" based on the size of the test rig, is there any clarification on this or is it generally to the test rigs manufacturers guidelines?

Show Replies (1)Comparing the contents on 2016 edition to the 2013, the headings and even the page numbers are exactly the same, can you provide a list of changes in point form ? Or highlights ? Further, how often will BESA intend to update this standard, it may seem ludicrous in doing so, but it does cost contractors a fortune.
