3 Terms and definitions, symbols and abbreviations
3.1 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in CR 12792:1997 and the following apply.
3.1.1
duciboard
rigid board composed of insulation material body with both sides faced: the outer facing comprising a duct vapour barrier, which makes the duct tight
NOTE Ductboards are fabricated into rectangular or multisided duct sections.
3.2 Symbols and abbreviations
The symbols and abbreviations are given in Table 1.
4 Requirements
4.1 Erosion and emission of particles
When tested in accordance with 72, at 2,5 times the maximum air speed recommended by the manufacturer of the ductboard, material from the inside surface of the ductwork shall not break away. flake off, or show evidence of delamination or erosion.
Emission of particles shall be less than 60 iglm3 for particles bigger than 0.5 jam. and no more than 4 igfm3 for particles bigger than 5,0 im.
4.2 Resistance against pressure (without reinforcements)
When tested In accordance with 7.3, air ducts and connector sections with joints, assembled in accordance with the manufacturer’s instructions, shall withstand without rupture an internal air pressure of 2,5 times the manufacturer’s rated positive pressure. but not less than 200 Pa.
For this test rupture is considered as evidenced by breaks, tears, rips or other openings greater than 4 mm. NOTE Plastic deformation is not considered to be a rupture
Any joining material shall remain intact to the extent that materials such as tapes do not become displaced more than a total for both edges of 4 mm from their initial position. There shall not be evidence of other damage, which would cause the sample to become unusable.
4.3 Air leakage factor and air tightness class
The air leakage factor s gwen in Table 2 and the air leakage rates in Table 3 when tested in accordance with prEN 1507.EN 13403-2003 pdf download.
