scope:

This Japanese Industrial Standard specifies the safety code for the parts of small refrigerating equipment using a compressor, which receive the refrigerant pressure, in order to ensure the safety against the refrigerant pressure. Small refrigerating equipment refers to the refrigerating equipment of which the refrigerating capacity of one refrigerant circulation system per day is 0.2 t or over to and excluding 5 t, using carbon dioxide and inert fluorocarbon (including specific inert gas) whose saturation vapour pressure at the temperature of 35 °C is over 0.2 MPa up to and including 3 MPa as the refrigerant. However, the following shall be excluded.

a) Refrigerating equipment used at the steam temperature of −60 °C or lower

b) Air conditioners for automobiles

NOTE Unless otherwise specified, "pressure" in this Standard refers to "gauge pressure".
