The Mexican Ministry of Health has proposed the draft Mexican Official Standard NOM-231-SSA1-2015 "Glazed ceramic, glazed pottery, porcelain articles and glassware – Maximum permissible limits of soluble lead and cadmium – Test method" to replace NOM-231-SSA1-2002.
Following are highlights of the proposed changes:
