FOREWORD
ASHRAE Standard 34-2010 revised the toxicity classification definition to use "Occupational Exposure Limit" (OEL) in place of "Threshold Limit Value-Time-Weighted Average" (TLV-TWA) and added OEL values to the refrigerant tables.
Addendum c harmonizes ASHRAE Standard 15 with Standard 34 to use OEL values as the refrigerant detector set point for refrigerating machinery rooms to actuate an alarm and mechanical ventilation.
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and strikethrough (for deletions) unless the instructions specifically mention some other means of indicating the changes.
