Customer Case: Air Ventilation Aging Test Chamber

Customer Background

A manufacturer specializing in wire & cable, plastic, rubber, leather and textile materials. The company runs a professional material performance and reliability laboratory, responsible for incoming inspection, R&D verification, aging performance evaluation and quality certification. It must conduct standardized thermal aging tests in strict accordance with UL, ASTM, CNS and JIS standards to ensure product safety, stability and service life.

Challenges Faced by the Customer

Unstable air exchange: Old equipment could not precisely control ventilation rate, leading to inconsistent aging conditions and poor repeatability of test data.

Temperature uniformity & accuracy insufficient: Large temperature deviation caused uneven heating of samples, unable to reflect real aging performance.

Non-compliant with standards: Failed to meet UL1581, ASTM-D2436, JIS K7212 and other specifications, which affected product certification and customer audits.

Lack of professional functions: No turntable for uniform heating, no dedicated ventilation measurement device, low test efficiency and low data credibility.

Safety and reliability risks: Incomplete protection system, potential hazards in long-term high-temperature operation.

Our Solution

We provided the customer with our Air Ventilation Aging Test Chamber with full-standard compliance and professional aging test performance:

Professional ventilation control system: Adjustable air exchange rate 3–200 times/hour, equipped with air exchange measuring device (per JIS K7212) to ensure stable fresh air supply.

High-precision temperature control: Temperature range RT+25℃ to 300℃, control accuracy ±0.5℃, resolution 0.1℃, uniformity ±2.5℃, heating to 250℃ in about 60 minutes.

Full standard compliance: Fully meets UL1581, ASTM-D2436, CNS3556, CNS742, JIS7212, JISB7757.
