Test methods of ceramic tiles—Part 15: Determination of lead and cadmium given off by tiles

This standard specifies a method for determining lead and cadmium released from ceramic tiles and applies to relevant testing activities for ceramic tile products. It is identical to ISO 10545-15:2021 and provides test procedures for evaluating the release of lead and cadmium from ceramic tiles, supporting product quality inspection, production control, and related compliance assessments. It fully replaces GB/T 3810.15-2016, with the scope adjusted from glazed tiles to ceramic tiles.
