Porcelain sculpture is a delicate art form that requires adherence to strict material and production standards to ensure quality, safety, and durability. The most important certifications and standards include:

1. ISO 13006 (Ceramic Tiles): While primarily for tiles, this standard influences porcelain material quality, ensuring consistency and performance.

2. FDA Compliance (USA): Essential for sculptures intended for functional use (e.g., tableware), verifying non-toxic, food-safe materials.

3. ASTM C242 (Ceramic Terminology): Standardizes terms and testing methods for ceramic arts, aiding in material selection.

4. EN 71-3 (European Toy Safety): Critical for sculptures accessible to children, limiting heavy metal migration.

5. RoHS Directive: Restricts hazardous substances in materials, vital for eco-conscious artists.

Additionally, kiln safety certifications (e.g., UL or CE marks) and local art material safety laws (e.g., California Proposition 65) may apply. Artists should prioritize these standards to enhance credibility, marketability, and user safety. Always verify certifications with suppliers and testing laboratories for compliance.
