Glassware and glass ceramic ware in contact with food; Release of lead and cadmium; Part 1 : Method of test

This document outlines a specific international testing protocol designed to evaluate the release of lead and cadmium from glass articles used for food service and from glass ceramics intended for similar applications. The approach focuses on defining the methodology required to assess the migration of these potentially hazardous substances from the surface of the glassware into designated simulant liquids under controlled conditions. The procedure establishes precise parameters for sample preparation, including the handling of various shapes and sizes of vessels, as well as the specific chemical composition of the extraction solutions used to simulate different types of food and beverages. It details the required exposure times, temperatures, and the analytical techniques necessary to quantify the concentration of released metals. By adhering to this framework, manufacturers and regulatory bodies can ensure that glass products meet safety criteria regarding the transfer of toxic elements into consumables, thereby contributing to the protection of public health. The methodology covers both the experimental setup and the subsequent data analysis steps to guarantee consistent and reproducible results across different laboratories worldwide.
