Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard is a revision of JG 2-2007 "Steel Plate Radiator". The main technical changes compared with JG 2-2007 are as follows.

--- Removed the terminology and definition of the single board heatsink;

--- Added the terminology and definition of double-plate without convection fins;

--- Added classification;

--- Increased materials and structure;

---Modified heat dissipation;

---Modified work pressure;

---Modified the thread quality requirements;

--- Modified the method for determining the adhesion of the coating;

--- Modified the inspection item list;

--- Modified the inspection sampling plan;

--- Added instructions for use.

This standard was proposed by the Institute of Standardization of the Ministry of Housing and Urban-Rural Development.

This standard is under the jurisdiction of the Building Environment and Energy Conservation Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development.
