PRE-CERTIFIED TEST SIEVES:
ALL of our ASTM E11 wire mesh test sieves or ASTM E161 electroformed nickel precision sieves can be pre-certified to include the Centerline® certification, a fully NIST traceable certificate of analysis.
When accuracy and traceability are vital components of your Quality Management System, certified sieves assure compliance with the ASTM E11 (American Society for Testing and Materials) specifications. Our Centerline® certification reports contain statistical data that is linked to each serialized sieve and provides detailed measurements traceable to the NIST (National Institute of Standards and Technology).
Certification Grade Levels:
- 200C – INSPECTION: Certificate contains inspection data from a percentage of apertures measured based on the ASTM E-11 standards table providing a confidence level of 99.0% that each sieve is within the specifications.
- 300C – CALIBRATION: Certificate data contains at least twice as many apertures measured than “Inspection” grade sieves, thereby providing the highest confidence level available of 99.73%.
