1.Equipment summary:
ASTM D5423 Rubber Heated Air Circulation Aging Test Machine used to test the material characteristic
for wire type, skin type, plastic, rubber, cloth, Equiped with a special ventilation regulator for maintain the fresh
air inside when heating. This testing machine design with sophisticated air-displacement adjustment device and
a digital voltage meter, current meter, watt-hours, the timer can be used to measure the air replacement rate.
Horizontal circulatory air supply system and both sides of airflow regulator to ensure the internal temperature
uniformity and stability.
2.main feature:
Rubber Heated Air Circulation Aging Test Machine used to study the rubber that is heated under the
rotary mode in a fixed period. Tested 1 day at 70 ℃, theoretically equivalent to 6 months exposed to the
outside atmosphere. The oven is equipped with motor-driven rotary disk, hot-air circulation system that ensure
uniform distribution of temperature. Reference to ASTM, JIS, GB and other testing specifications.
3.Corresponding standard:
Accord with ASTM D5423-9(R2005)(Ⅱ-Type oven)and ASTMD 5374-93(2005) UL-1581,GB,VDE,JIS,IEC
4.Applicable industries:
ASTM D5423 Rubber Heated Air Circulation Aging Test Machine used to test the material heat-resisting for
polymer materials (plastics, plastic) and electrical insulation materials, such as: wire and cable sheathing,
heat-shrinkable tubing, rubber or PVC materials.
