resistance and sufficient hardness. The outer wall surface flatness tolerance shall not exceed 3 mm/m.
Vertical tolerance between the outer wall must not exceed 0.2%, excluding the
back. Coating surface shall be smooth and bright, in uniform color, without
significant flow of scars, pits, wrinkles, bubbles, missing coating, a collection of
sand and scratches or other defects. Decorative coating of electroplating shall be smooth and fine, without
spots, pinhole bubbles and coating peelings. Plastic surface shall be smooth, in uniform color, without cracks,
bubbles, significant shrinkage and deformation or other defects. Labels and all signs shall be complete. Labels shall comply with the
requirements according to 7.2. Freezer shall have power indicator.
4.1.8 Size The deviation between freezer dimensions (length, width, height) and
the dimensions marked on the label must meet the following conditions.
the deviation between the actual measured value and the rated is within ±0.3%
rated ±3 mm. Rated effective volume is represented by m3. The effective volume of
freezer is measured and calculated according to Annex A. Its value shall not be
less than the rated value. For display freezer, when its total display area is measured according
to the provisions of GB/T 21001.2. its measured value shall not be less than the
rated value.
4.1.9 Electroplating
After the metal electroplating of freezer are conducting salt spray test according
to 5.3.12, examine the corrosion of electroplating layer surface. The
electroplating layer does not allow to have rust.
4.1.10 Coating of inner and outer surface metal
After the inner and outer surface metal coating of freezer are conducting the
test according to and 5.3.14, examine the coating surface conditions
which shall be qualified.

For the cabinet which uses water-cooled condensing compressor, it shall adjust
the inlet water temperature of condenser to 28±1°C AND ensure that the
average temperature difference between the inlet water and the outlet water
during compressor switching is 6±0.5°C.
In principle, temperature data collection uses automatic recorder. If manual
reading record is used, it shall not be less than 4 times per hour. The reading
moment shall reflect the temperature peak value of the cabinet, so as to
