When it comes to Other Fenestration Assemblies, NBC 2020 Section 5.9.3. provides minimal requirements for air leakage tested at an air pressure difference of 75 Pa (1.57 psf) that is not greater than 0.2L/(s•m²) [0.30 cfm/sf] as per ASTM E283-04 (refer to Sidebar 3, page 4).
Water penetration compliance for NBC 2020 is achieved with either ASTM E331-00 or ASTM E547-00. The penetration resistance of the Other Fenestration Assemblies products must be capable of resisting driving rain pressure as determinate using the protocol and the climate design data defined in CSA A440S1-19.
ASTM E330/330M-14 is the acceptable protocol for structural and environment loads by reference in the NBC 2020 notes. Regarding loads, consult the NBC 2020 “Part 5 – Environmental Separation, Section 5.2 Loads and Procedures,” to review all loads affecting the Other Fenestration Assemblies due to a project’s specific conditions, location, and design. Even if these are not part of mandatory testing protocols, various loads can affect the fenestration components, and may require either project-specific testing or calculations.
Additional testing methods listed in the NBC 2020 notes include AAMA 501-05, AAMA 501.1-05, AAMA 501.4-09, AAMA 501.5-07, and AAMA 501.6-09 (refer to Sidebar 1 on previous page). These are not mandatory but offer helpful guidance for the specifications professional.
