Abstract BS 3473-4.2:1989 is a British Standard that specifies methods for determining the hydrolytic resistance of the interior surfaces of glass containers used in laboratory settings. The standard involves subjecting the glass containers to water at 121°C for 60 minutes and then measuring the amount of sodium or other alkali metal or alkaline earth oxides released into the extraction solution using flame atomic emission or absorption spectrometry. Based on these measurements, the glass containers are classified according to their hydrolytic resistance. ​
