A ballot to revise NAFS-11, and NAFS-08 is now open. This revision is being proposed to address the availability of side hinged door lock and latching hardware, tested to meet the water penetration resistance testing requirements of NAFS-11. Similar revision is needed to NAFS-08, since this is the official version of NAFS referenced by the Canadian National Code.

Background and Rationale:

Side hinged entry doors are addressed as an operating type in both NAFS-08 and NAFS-11. Side hinged entry doors are required to be tested with locking and latching hardware installed. This is necessary in order to evaluate the structural load resistance, air penetration resistance, water penetration resistance and other performance values of the structural materials, joinery and weather sealing components of the system. However, locking and latching hardware is not always supplied by the system manufacturer with the rated assembly, and even if so, is frequently replaced with an aftermarket installation, and beyond the control of the door system manufacturer.

While some hardware producers do offer compliant hardware, the vast majority of aftermarket, side hinged entry door hardware available to and used by consumers does not have water penetration resistance testing information available. Under the current language in the NAFS-08 and NAFS-11 standards, the use of this aftermarket hardware could be interpreted as voiding compliance.

In order to alleviate this consumer issue, revisions are being proposed to the standards. The revisions permit exclusion of side-hinged door locking and latching hardware from testing for water penetration resistance. In effect, the revisions permit locking and latching hardware at any level of water penetration resistance to be used in a tested and rated side-hinged door assembly without voiding compliance or certification. It also preserves the need for locking and latching hardware to meet structural load resistance and other performance measure of the standard, regardless of whether the hardware was aftermarket or furnished by the door system manufacturer.
