1. Abstract
A series of amendments to the international standards concerning
refrigeration and A/C equipment is almost available to provide the additional
safety measures required for the design, repair and service of refrigeration and
A/C equipment using flammable refrigerants. These amendments will provide
the framework to develop future refrigeration technology employing
hydrocarbons. This paper reviews the different existing standards and the
forthcoming drafts highlighting the maximum charge and room area limits as
well as the specific requirements for air-conditioning and refrigerating
equipment operating with hydrocarbons.
