Recently, China issued the Action Program for Promoting Large-scale Equipment Renewal and Consumer Goods Trade-in (hereinafter referred to as the Action Program), which systematically deploys 20 specific measures around the implementation of the four major actions of equipment renewal, consumer goods trade-in, recycling, and standard enhancement. Since the release of the Action Program, provinces and municipalities have responded to the policy by gradually promoting the relevant work and formulating provincial and municipal plans to promote large-scale equipment renewal and consumer goods trade-in.

Rain test chamber is a test instrument to test whether the waterproof is good, the figure of this equipment can be said to be everywhere, applied in various places. Small to our usual use of cell phones, flashlights and other lighting apparatus; large to the aerospace industry, lighting systems, signaling device testing and so on. Waterproof has always been a lot of industry can not get around a topic, a lot of equipment once the rain and other wet, its service life will be greatly reduced, this equipment in the waterproof performance test link plays a vital role.

The humidification process in a constant temperature and humidity test chamber essentially involves increasing the water vapor partial pressure. The initial humidification method was to spray water onto the chamber walls and control the water temperature to regulate the saturation pressure of the water surface.

During the past twelve months, several third-party testing bodies and OEM laboratories reported the same problem: when running dust tests in accordance with GB/T 4208, IEC 60529 or MIL-STD-810, the batch cycle has stretched from 48 h to 72 h, even 96 h, while energy consumption has risen by more than 30 %.

By subjecting products to various temperature environments—such as high temperature, low temperature, and alternating humidity—constant temperature and humidity test chambers can evaluate the heat resistance, cold resistance, dryness resistance, and moisture resistance of materials under different climatic conditions.
