1.5 
This Standard applies to compressor packages intended for use on a system voltage of 600 V or less, designed to be used in accordance with the Canadian Electrical Code, Part I. 

1.6 
A compressor package is investigated under this Standard for reliable and safe operation at ambient temperatures of -40 ºC (-40ºF) and the manufacturer's declared maximum ambient temperature rating; this declared rating is not less than 40 ºC (104ºF).
