This standard specifies a unified test method for determining the resistance of glass to erosion in hydrochloric acid solution at 100°C, providing a critical technical basis for evaluating the chemical stability of pharmaceutical packaging, laboratory instruments, and industrial glass. The core of the method involves subjecting glass samples to a specified duration of immersion in hydrochloric acid solution under strictly controlled conditions. Subsequently, flame emission or atomic absorption spectrometry is employed to quantitatively analyze the content of metal ions released into the immersion solution, thereby objectively assessing the corrosion resistance of the glass material. In practical testing, the process primarily relies on high-precision analytical instruments such as flame atomic absorption spectrometers or flame photometers equipped with elemental hollow cathode lamps. These instruments enable the sensitive determination of trace element concentrations in the leachate, ensuring the accuracy and reproducibility of the test results.
