Specifies requirements for carbon dioxide systems utilizing high or refrigerated low pressure carbon dioxide as the fire extinguishant. This Standard was prepared as a companion document to AS 4214.1-1995.

This Standard complements AS 4214.1 and sets out the requirements for carbon dioxide systems, utilizing high or refrigerated low pressure carbon dioxide as the fire extinguishant.The carbon dioxide shall comply with the requirements of AS 4078.General principles may well apply for other uses (e.g. maritime use). However, additional considerations may have to be taken into account which are beyond the scope of this Standard.NOTE: A commentary on certain aspects of this Standard is given in an advisory manner in Appendix A. It relates to specific Clauses in the text identifying relative information bearing, in each instance, the Clause number and title preceded by the letter 'A', e.g. A1.5 Uses and limitations of carbon dioxide.
