Overview
EN ISO 3262-6:2022 specifies the requirements and test methods for precipitated calcium carbonate (PCC) used as an extender in various industrial applications. Developed by ISO/TC 256 in collaboration with CEN/TC 298, this standard ensures consistent quality and reliable testing for PCC products across Europe and internationally. It supersedes the previous edition EN ISO 3262-6:1998 and includes updated technical specifications vital for manufacturers, quality control laboratories, and end-users.
This standard targets industries requiring precise quality control of pigments and extenders, particularly where PCC is involved. It defines essential properties such as chemical composition, particle size, and purity, as well as detailed procedures for their accurate determination.
Key Topics
Applications
-
Paints and Coatings: PCC enhances brightness, opacity, and consistency in paints by serving as a filler/extender. Compliance with EN ISO 3262-6 ensures optimal dispersion and chemical stability.
-
Plastics Industry: PCC improves the mechanical properties and surface finish of plastics. Standardized PCC helps maintain product uniformity.
-
Paper Manufacturing: In papermaking, PCC acts as a pigment and filler to improve brightness and printability. This standard supports quality control for consistent paper attributes.
-
Rubber and Adhesives: PCC is used to modify viscosity and mechanical strength; meeting specific requirements assures performance in formulations.
-
Laboratory Quality Assurance: Enables labs to perform accurate and comparable chemical and physical tests of PCC batches, ensuring reproducibility and regulatory compliance.
