GB/T 25494-2010

This standard specifies test methods for determining the chemical composition of getters, which are materials used to remove residual gases in vacuum or sealed electronic devices. It is applied in the manufacturing and quality control of vacuum tubes, cathode ray tubes, and other electronic components where getter performance directly impacts device reliability and lifespan. The methods cover techniques such as gravimetric analysis, titration, and atomic absorption spectrometry to ensure consistent getter material quality.
