The containers are subjected to attack by 121 degrees centigrade for 60 min. The resistance is measured by determining the amount of sodium or other alkali metal or alkaline earth oxides in the extraction solution using flame atomic emission or obsorption spectrometry. The principle, reagents, apparatus and procedure including the classification of the container according to the hydrolytic resistance are specified.
