Scope:

The standard is restrictive in minimum storage temperature points. The addition of higher minimum storage temperatures will allow additional system design options, features and new technologies in certain applications.

During conversion to include as a ULC standard, some values were found to be incorrect. In Table 35.1, correct error in units of density from (g/m² to (g/m³). In Clause 35.3.1.2, correct error in Class B fire test area from 0.25 m² to 0.23 m².

Project need:

Amendments are necessary to an existing Joint Canada-US standard.
