Re-Certify Your Sieves

Test Sieve Re-Certification with Centerline®
Periodic Certification (Inspection or Calibration grade) of test sieves is recommended as with any precision laboratory instruments. Generally, the finer woven wire cloth requires more frequent inspections. Re-Certification schedules greatly depend upon your media, frequency of usage, sieve handling and care, and your internal quality system requirements.

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%. 

Re-Certification Schedule:

Refer to the table below for the recommended schedule. Also above are instructions on how to submit your sieve for re-certification.
