T/CCIA 0002-2020 Clay is used to wrap red pigment

Scope

Scope: This standard specifies the normative reference documents, terms and definitions, product classification, technical requirements, test methods, inspection rules, packaging, marking, transportation, and storage for ceramic wrapping red pigments. This standard applies to ceramic wrapping red pigments in the form of zirconium silicate-wrapped cadmium selenide. Main technical content: - Color difference (compared with the standard sample) E ≤ 1.5 - Volatile matter (%) ≤ 0.5 - pH value of water suspension 6.0–9.0 - 325 mesh sieve residue (%) ≤ 0.6 - Water-soluble matter ≤ 0.5 - Loss on ignition at 1200°C ≤ 1.0 - Lead (Pb) content, mg/kg ≤ 600 - Cadmium (Cd) migration, mg/dm2 ≤ 0.02 - Radioactive nuclide limits Manufacturers shall provide the level of radioactive nuclides in the product in accordance with GB 6566-2010. Note 1: The migration of lead and cadmium and the lead and cadmium content in the powder shall be implemented in accordance with the provisions of Article 5.4 of QB/T 2455 for lead-free cadmium pigments. Note 2: If the user has special requirements for color and other technical indicators, they may be agreed upon separately. However, the tests shall be conducted in accordance with the test methods specified in this standard.
