This is the glaze-and-glass RELEASE basis; it is deliberately NOT the Reg (EU) 10/2011 plastics-simulant convention, and a plastics specific migration limit is never substituted for a release limit on this family.. No government sets a numeric heavy-metal limit for this product form, so every panel analyte is held under mandatory analytical control or a substantiated not-material determination rather than an invented ceiling.
