Subject:
Environmental Separation Table 5.9.1.1.
Title:
Replacement of Reference to Outdated CAN/CGSB Standard with a Reference to an ASTM Standard
Description:
This proposed change replaces the reference to CAN/CGSB-37.58-M86, “Membrane, Elastomeric, Cold-Applied Liquid, for Non-Exposed Use in Roofing and Waterproofing,” with a reference to ASTM C836/C836M-18, “Standard Specification for High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course,” in Table 5.9.1.1.
Problem
CAN/CGSB-37.58-M86, “Membrane, Elastomeric, Cold-Applied Liquid, for Non-Exposed Use in Roofing and Waterproofing,” which is currently referenced in Table 5.9.1.1. of Division B of the NBC, had not been updated since 1986 and was withdrawn in 2005.
The withdrawal of the standard over 15 years ago means that industry is no longer using this standard as a reference for minimum performance or material suitability. Therefore, if the standard were to remain in the NBC, it would cause confusion and conflict between designers, manufacturers, authorities having jurisdiction and the legal community. These conflicts would occur when
- authorities having jurisdiction request documentation from manufacturers during permit reviews to prove Code compliance,
- designers require Code compliance for use of their design specifications on a project, or
- lawyers demand proof of Code compliance during possible court cases.
Justification
At the mid-cycle review of updates to the standards currently referenced in Table 5.9.1.1., it was determined that CAN/CGSB-37.58-M86
• was withdrawn in 2005, and
• is no longer used in practice.
Therefore, it was agreed to replace the reference to this withdrawn standard with a reference to ASTM C836/C836M-18, “Standard Specification for High Solids Content, Cold Liquid-Applied Elastomeric Waterproofing Membrane for Use with Separate Wearing Course.”
Replacing the reference
- removes the need to prove compliance with a standard that is no longer relevant to the industry
- provides Code users with a relevant and up-to-date standard with which to comply.
This proposed change would eliminate potential conflicts and confusion for designers, manufacturers, authorities having jurisdiction and the legal community, as noted above.

Impact analysis
This proposed change is expected to have a positive impact in that it would resolve all potential conflicts created by the Code reference to an outdated standard as a minimum requirement and align the Code with current industry practice.
Enforcement implications
Replacing the reference to the withdrawn and outdated CGSB standard with a reference to an up-to-date ASTM standard as a minimum requirement would eliminate the conflict that could be created if an authority having jurisdiction were to demand proof of compliance to a standard that is not used by industry.
Who is affected
Designers, specifiers, manufacturers, building owners, building officials, lawyers and contractors. These groups would benefit from the elimination of the potential conflicts addressed above.
