Heat Distortion Test
Standard Compliance: UL 44, UL 94, UL 1581, UL 2556 and other related standards
Two category of ovens in compliance to ASTM D 5243 Type II Ovens and ASTM D 5374 forced air circulation oven for 8-20 or 100 ? 200 air changes per hour
Method 1: Based on Flow Meter Measurement
The equipment is fitted with rotameter. An external air source is arranged by the customer to provide forced air inside the oven via flow meter fitted with needle valve control.
Method 2: Air Velocity Method
Air blow with air velocity tunnel equipped with differential air velocity measurement prove is connected to the oven.
Fresh air is admitted by the high capacity blower, controlled by means of damper & measured using differential air velocity sensor for required 100-200 air changes per hour.
Heat distortion assembly is affixed inside the aforesaid oven
Device?is?used for measuring the deformation test of wire under a certain temperature and load.
According to the standard?UL-1581 Reference standard for electrical wires, cables and flexible cords, JIS C3112 clause 541-559 and 560.
For use with ageing oven with 100-200 air changes.
3 test stations suitable for various cable sizes.
