The wire and cable industry is experiencing rapid growth, but many companies are still focused on quantity rather than quality. This highlights the urgent need to improve product quality. To ensure the safety and longevity of cables, it's essential to implement advanced quality control measures, including heat aging performance testing. This test is typically conducted in a gas aging chamber, where two key parameters are controlled: temperature and air exchange. While temperature is often closely monitored and considered critical for calibration, the importance of air exchange is frequently overlooked. However, air exchange plays a vital role in the aging process. When the wind speed is high, more air is exchanged, leading to better convection and a more pronounced aging effect. Conversely, lower wind speeds result in less air exchange and slower aging. To maintain consistent and reliable results, standards such as JB/T4278.6-2011 "Verification Method for Natural Ventilation Heat Aging Test Chamber for Rubber and Plastic Cables" must be followed. According to this standard, the air inside the chamber should be completely exchanged 8 to 10 times per hour at the specified test temperature. This ensures that the aging process remains effective and meets required performance levels. In summary, while the wire and cable industry is expanding quickly, focusing on quality through proper testing methods like heat aging is crucial. Paying attention to both temperature and air exchange helps ensure that products meet safety and durability standards, which is essential for long-term success in the market.
