Formed in 1948, the ASTM Committee C21 researches and develops definitions, test methods, and specifications for ceramic whitewares and related products. This Committee typically meets twice a year, usually in the fall and spring. With a current membership of 181 industry professionals and experts, C21 has jurisdiction over 58 standards published in the Annual Book of ASTM Standards, Volume 15.02.
Many of the standards developed by C21 include important test methods utilized and referenced commonly by the North American ceramic tile industry. TCNA plays a vital role facilitating the business of the Committee.
