Code Reference(s):
NBC20 Div.B 5.9.1.1. (first printing)
Subject:
Environmental Separation Table 5.9.1.1.
Title:
Deletion of Reference to Duplicate Standard
Description:
This proposed change deletes the reference to ASTM D2178/D2178M-13a, “Standard Specification for Asphalt Glass Felt Used in Roofing and Waterproofing,” from Table 5.9.1.1.
This change could potentially affect the following topic areas:

Problem

Part 5 of the NBC currently references both ASTM D2178/D2178M-13a, “Standard Specification for Asphalt Glass Felt Used in Roofing and Waterproofing,” and CSA-A123.17-05, “Asphalt Glass Felt Used in Roofing and Waterproofing”; however, ASTM D2178/D2178M was adopted, with Canadian deviations, as CSA-A123.17.

If ASTM D2178/D2178M 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., the Standing Committee on Environmental Separation determined that ASTM D2178/D2178M-13a and CSA-A123.17-05 are currently referenced in Part 5 despite the fact that ASTM D2178/D2178M has been adopted, with Canadian deviations, as CSA-A123.17. Therefore, the Standing Committee agreed to delete the reference to ASTM D2178/D2178M.

Deleting reference to ASTM D2178/D2178M from the NBC eliminates potential conflict 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 referencing two duplicate standards for compliance.

Enforcement implications

Removing the reference to ASTM D2178/D2178M-13a from the NBC would also remove the potential confusion and conflict that could be created if an authority having jurisdiction were to demand proof of compliance to both standards.

Who is affected

Designers, specification writers, manufacturers, building owners, building officials, lawyers and contractors. These groups would benefit from the elimination of the potential confusion and conflict addressed above.
