Notice to Specifiers - Clarification on CSA G164 Application

CSA G164 was first published in 1965, with subsequent revisions in 1981 and 1992. It was formally withdrawn in 2008 due to reduced industry uptake, overlap with ASTM galvanizing standards, and limited overall support, despite evidence of strong technical performance in certain utility-related applications. The withdrawal was met with notable resistance, particularly from sectors that continued to rely on its provisions.

‍

Recognizing this ongoing need, CSA G164 was reinstated in 2018 under the Technical Committee on Communication and Power Line Hardware.

‍

It is important to note that CSA G164 is intended primarily for the hot-dip galvanizing of irregularly shaped articles used in electrical and communication systems and includes associated methods for testing and compliance.

‍

As such, care should be taken when referencing CSA G164 in specifications for applications outside of this intended scope. Aligning the selected standard with the specific project requirements and end-use conditions will help ensure clarity, consistency, and optimal performance outcomes.

Supporting informed specification practices across Canada is a core mission of CGI-IGC, with the objective of creating an aligned national network of Canadian resources and procedures to support all stakeholders.
