This tester is designed to test the aging resistance specially for rubber, plastic and some insulator materials. Different from normal aging oven, this tester has
a.Temperature constancy
b.Temperature uniformity
c.Heat-up speed after door opened
d.Wind speed and air exchange rate of testing chamber
e.Seal of heat isolation of the testing chamber
f.Special apparatus for adjusting air exchange
g.Confirms to testing norms:
JIS K-7217, K-7623, K-6301, ASTM D-2436, D-573, UL-746B, IEC-540, BS-6746, 903, ISO/DIS 4577
Specifications:
Measuring Method Of Air Change
This method measures the air change rate of the std type oven as follows:
N=[3590 (X-Y)x2]/[VxDx∆T]
where:
N: number of changes of air per hour
X: Power consumption during air change (W)
Y: Power consumption during no air change (W)
V: total volume of oven (cu. cm)
D: Density of oven ambient air (g/cu. cm)
∆T: Temperature difference inside/outside oven (¢XC) |
