This standard covers elastomer hoses ranging in size up to and including those with a 4-in (10-cm)inner diameter. The normal operating pressures of the applications for these hoses are between 125 psig (860 kPa) and 400 psig (2760 kPa). Therefore, the maximum allowable working pressure (MAWP) of the hoses shall be at least 450 psig (3100 kPa). In addition, they shall be designed to operate in a temperature range between -65℉ and 125℉ (-54℃ and 51.7℃).
It is prepared as a guide for manufacturers and users of carbon dioxide hoses and represents the best currently available industry practice. Information on carbon dioxide can be found in CGA G-6, Carbon Dioxide[2].
