GB 4806 Testing against the EU Plastics Regulation Limits
Testing plastic food contact articles under China GB 4806 and EU Regulation 10/2011 requires harmonizing simulant choices, thresholds, and batch trace files.
CMA Accreditation
Meaning
Official laboratory certification by Chinese authorities ensures that polymer testing facilities produce legally binding data. Obtaining CMA accreditation is a prerequisite for any laboratory testing resin properties or food-contact safety under Chinese national standards. This certification guarantees that testing equipment and laboratory practices comply with regulatory rules.
Quality Audit
Measurement procedures for polymer properties such as density or melt index must be thoroughly documented. A laboratory with CMA accreditation demonstrates that its testing instruments are calibrated against national standards. This audit ensures traceability.
Market Compliance
Material certification for imported or domestically produced plastics requires test reports bearing the official red seal of the accredited laboratory. Compliance with CMA accreditation regulations ensures that polymer datasheets for Chinese manufacturing sites are legally recognized. Part failures are minimised when raw resin testing is conducted by certified personnel using standardised methods.
Laboratory Management
Instrument calibration and sample handling are scrutinized during the annual inspection of the laboratory. Compliance requires a robust quality management system that monitors ambient temperature and relative humidity in the testing room, as these variables alter the measured tensile and impact properties of test specimens. Strict document control prevents uncertified test sheets from entering the supply chain.
