With all units shifting into overhaul one by one, Zhenghe Group’s quality testing center has turned its attention to test equipment, air sampling equipment, oxygen content, and flammable and poisonous gases.
Over the years, the company has continued to increase its unit scale. Therefore, more and more places need air sampling, with increasingly frequent tests. The testing center made early preparations, improved testing methods, and started to use equipment to analyze oxygen content, which greatly increased efficiency and data accuracy.
The new measures apply external standard methods that are subject to outer temperature, humidity, pressure and sample feeding speed. The center launched trainings and formulated strict sampling procedures to minimize deviations. It required air calibration methods to ensure sampling accuracy and strict control of sampling speed to ensure evacuation. The center has used the methods to test all equipment and oxygen content over 300 times, paving a solid road for smooth testing work and inspector safety.
