4.2.4 Thermal resistance
4.2.4.1 High temperature resistance test
After high temperature resistance test at (80°C ± 3°C)/24 h, the coating of enclosure shall not crack, bubble or fall off; the paper filter element shall be free from burning, scorching, fracturing, scattering, etc.; filter material and adhesive, end cap and adhesive shall not break apart and fractures, cracks, breakages, etc. are not allowed. 4.2.4.2 Low temperature resistance test
After low temperature resistance test at (- 40°C ± 3°C)/24 h, the coating of enclosure shall not crack, bubble or fall off; the paper filter element shall be free from fracturing, scattering, etc.; filter material and adhesive, end cap and adhesive shall not break apart and fractures, cracks, breakages, etc. are not allowed.
Mount filters according to the formal installation method; no defects are allowed after vibration test based on the parameters of Clause 10 of QC/T 32-2006, such as fractures and deformations.
