CENTERLINE® Premium Sieve CertificationOur Premium Sieve Certifications are an add-on service when you purchase a new sieve or can be performed on your existing sieves.
By employing sophisticated optical technology - like the CENTERLINE® Measurement System - we ensure your test sieves comply with the ASTM E 11 standards created by the American Standards Testing Materials International Committee. It's yet another method to elevate quality control and provides data that can become an integral part of your Quality Assurance Program.
ASTM E11 SpecificationsThe ASTM E11 specification includes three different grades (compliance, inspection and calibration) for test sieves, wash sieves and woven wire cloth. The added levels of certification allow customers the ability to more precisely evaluate where their sieves lie in relation to the current E11 standards. The standards table includes dimensions and permissible variations for the sieve cloth itself and inspection criteria for the three grades. The following documentation is provided for each grade:
Advantech continues to provide sieve certification services in compliance with the older ASTM E 11-04 standards. This allows your older sieves to be re-certified with the same level of compliance criteria as previously performed.
Adjusting to ever-changing needsSetting quality standards above everything else, Advantech Manufacturing has been at the forefront of the particle sizing industry. Depending on your particular application, the current ASTM E11 specification limits of your test sieve may be too broad. With the CENTERLINE® Measurement System, we've perfected the ability to evaluate exactly where your sieve lies in relation to the ASTM E11 standards.
Quality AssuranceBy utilizing a sophisticated image analyzer traceable to the National Institute of Standards and Technology (NIST), your sieve is scanned for irregularities. Physical measurements are taken in a midpoint orientation of the wire in the X and y directions (warp and weft), and the wire diameters are measured to ensure compliance with the ASTM E11 specification. The data gathered is summarized in a comprehensive verification report that includes:
Each sieve is serialized for accurate identification in your Quality Assurance Program.
As with any precision lab instrument, periodic inspection or calibration is recommended. Re-certification depends upon sieve usage, care and your internal quality system requirements. As a guideline, we recommend certifying your sieves on a semi-annual basis.
