do the new I-codes 2012 require air/water penetration testing / inspection?

can some one point me to the chapter & verse in the code?

a vendor has suggested this is required in Maryland & district of columbia...also commented that if a general contractor violates certain air leakage rates that the federal government can fine the general contractor...sounded related to the air barrier association of america.
 
Blower door testing and duct testing were introduced in the 2009 IRC.....I believe...., not exactly sure what you are talking about....

Not sure but check r402.4.4

Thanks.I think I was trying to find the requirement for an air leakage test in commercial.I did see where the 2012 IECC is much more comprehensive & at length detailed regarding air leakage compared to 2009 IECC; snip image captures below.And in particular saw where the building test is called out more specifically in 2012 IECC C402.4.1.2.3 (highlighted yellow).

In IECC 2012--

Full building test is option number 3--

C402.4.1.2 Air barrier compliance options.

A continuous air barrier for the opaque building envelope shall comply with Section C402.4.1.2.1, C402.4.1.2.2, or C402.4.1.2.3.

C402.4.1.2.1 Materials.

Materials with an air permeability no greater than 0.004 cfm/ft2 (0.02 L/s • m2) under a pressure differential of 0.3 inches water gauge (w.g.) (75 Pa) when tested in accordance with ASTM E 2178 shall comply with this section. Materials in Items 1 through 15 shall be deemed to comply with this section provided joints are sealed and materials are installed as air barriers in accordance with the manufacturer’s instructions.

1. Plywood with a thickness of not less than 3/8 inch (10 mm).

2. Oriented strand board having a thickness of not less than 3/8 inch (10 mm).

3. Extruded polystyrene insulation board having a thickness of not less than 1/2 inch (12 mm).

4. Foil-back polyisocyanurate insulation board having a thickness of not less than 1/2 inch (12 mm).

5. Closed cell spray foam a minimum density of 1.5 pcf (2.4 kg/m3) having a thickness of not less than 11/2 inches (36 mm).

6. Open cell spray foam with a density between 0.4 and 1.5 pcf (0.6 and 2.4 kg/m3) and having a thickness of not less than 4.5 inches (113 mm).

7. Exterior or interior gypsum board having a thickness of not less than 1/2 inch (12 mm).

8. Cement board having a thickness of not less than 1/2 inch (12 mm).

9. Built up roofing membrane.

10. Modified bituminous roof membrane.

11. Fully adhered single-ply roof membrane.

12. A Portland cement/sand parge, or gypsum plaster having a thickness of not less than 5/8 inch (16 mm).

13. Cast-in-place and precast concrete.

14. Fully grouted concrete block masonry.

15. Sheet steel or aluminum.

C402.4.1.2.2 Assemblies.

Assemblies of materials and components with an average air leakage not to exceed 0.04 cfm/ft2 (0.2 L/s • m2) under a pressure differential of 0.3 inches of water gauge (w.g.)(75 Pa) when tested in accordance with ASTM E 2357, ASTM E 1677 or ASTM E 283 shall comply with this section. Assemblies listed in Items 1 and 2 shall be deemed to comply provided joints are sealed and requirements of Section C402.4.1.1 are met.

1. Concrete masonry walls coated with one application either of block filler and two applications of a paint or sealer coating;

2. A Portland cement/sand parge, stucco or plaster minimum 1/2 inch (12 mm) in thickness.

C402.4.1.2.3 Building test.

The completed building shall be tested and the air leakage rate of the building envelope shall not exceed 0.40 cfm/ft2 at a pressure differential of 0.3 inches water gauge (2.0 L/s • m2 at 75 Pa) in accordance with ASTM E 779 or an equivalent method approved by the code official.

C402.4.2 Air barrier penetrations.
 
A side note we got a request to use the provisions of the 2012 IgCC Green construction code to modify the vestibule provisions of the 2009 IECC by using the air curtain permitted in the IgCC.
