The Ventilation Aging Test Chamber is designed for accelerated aging evaluation of wires, leather, plastics, rubber, and fabrics. By maintaining fresh air circulation while uniformly heating specimens at controlled temperatures and durations, the chamber enables observation of pre- and post-aging performance—including yellowing resistance, delamination, shrinkage, elongation, and retention rate. For wire and cable testing, the chamber features a specialized ventilation volume adjustment to ensure continuous fresh air during thermal exposure.
Application
The chamber is suitable for testing and evaluating the aging characteristics of various materials and products, including:
(1) Electrical wires and cables (PVC, XLPE, or rubber-insulated cables)
(2) Leather products (footwear, upholstery, garments)
(3) Plastics and polymer components (automotive, electronics, packaging)
(4) Rubber materials (seals, hoses, gaskets)
(5) Fabrics and textiles (protective clothing, industrial fabrics)
(6) Quality control and R&D in manufacturing and material development
Standards
This instrument is designed in compliance with the following international standards:
(1) UL 1581 – Electrical Wires and Cables
(2) ASTM D2436 – Accelerated Aging of Insulated Wire and Cable
(3) CNS 3556 – Plastic Materials Thermal Aging
(4) CNS 742 – Rubber Materials Test Methods
(5) JIS K 7212 – Wire and Cable Thermal Aging Test
(6) JIS B 7757 – Plastic and Rubber Material Aging
(7) CE Certification (Conformité Européenne)
Features
Wide Temperature Range: Ambient +25°C up to 300°C for versatile aging tests.
