5 Requirements
The air cooler shall meet the requirements of this standard. The air cooler with
additional functions shall also meet the requirements of the corresponding
national and industry standards, meanwhile be manufactured according to the
drawings and technical documents approved by the prescribed procedures.
5.1 Environmental conditions of use
a) Ambient temperature: 5 °C ~ 43 °C.
b) The relative humidity of the air is below 95% (at a temperature of 25 °C).
5.2 General requirements
5.2.1 Appearance:
a) The surface of the plastic parts shall be smooth and even, with uniform
color; it shall not have defects such as bubbles, spots, obvious scratches.
b) The main surface of the electro-plated parts shall be smooth and fine; the
color shall be uniform. There shall be no defects such as peeling, bottom
exposure, blister, deformation.
c) The surface of the coated parts is flat and smooth; the coating is firm.
There shall be no defects such as spots, pinholes, blisters, falling off.
5.2.2 Anti-rust of electro-plated parts:
