PRE-CERTIFIED TEST SIEVES:
ALL of our ASTM E-11 wire mesh test sieves or our 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 E-11 (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%.
