Advantech Manufacturing employs sophisticated optical technology - CENTERLINE® Measurement System - to ensure that test sieves comply with the ASTM E 11 specifications.
The recently approved revisions to the ASTM E 11 standards by the American Standards Testing Materials International committee have allowed for an increased confidence level for accuracy of test sieves, wash sieves and woven wire cloth. The specifications require manufacturers to test the wire cloth using various methods of optical comparison or computer measuring devices that measure the size of the openings and wire diameters within the test sieve for nominal dimensions and permissible variations for sieve cloth.
"New" in 2009, the ASTM committee has developed three grades within the E 11-09 standard: compliance, inspection and calibration:
Compliance grade sieves come with basic documentation from the sieve manufacturer that it has been inspected and found to be made in compliance to the standard.
Inspection grade sieves are supplied with an Inspection sieve certificate containing inspection data that has a percentage of openings and wire dimension measured based on the standards table providing you with a confidence level of 99% that your sieve is within the specifications.
Calibrated grade sieves are supplied with a Calibration sieve certificate containing inspection data detailing at least twice as many apertures measured than inspection sieves, thereby increasing the confidence level to 99.73%.
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.
ASTM E 11-04 Sieve Certification is supplied documentation which is based on the older standard guidelines. The E 11-04 standard varies in that it has a fixed number of measured openings per sieve, in comparison with the E 11-09 inspection and calibration grades which are based on a percentage of openings measured.
According to Tony Romano, Vice President, Advantech Manufacturing, Inc, "Depending upon your particular application, your sieves may be too broad in relation to the ASTM E 11 standards. The added levels of certification allow customers the ability to more precisely evaluate where their sieves lie in relation to the E 11-09 standards. Yet another way Advantech makes sure your quality assurance guidelines are met."
