ASTM Test Sieves

Gilson ASTM test sieves are available in all mesh opening sizes. These sieves meet ASTM E11 and AASHTO M 92 requirements for Compliance Test Sieves, and are serial numbered and supplied with certificates of manufacturing conformance. Verification of New Sieves upgrades ASTM and ISO Test Sieves to Inspection or Calibration grade.

ASTM Test Sieves are available in three styles – stainless steel frame with stainless steel cloth, brass frame with brass cloth, or combination brass frame with stainless steel cloth. ASTM Test Sieves come in several diameters: 3in (76mm), 6in (152mm), 8in (203mm), 10in (254mm), 12in (305mm), and 18in (457mm) and full or half-height frames with different sieve sizes for a wide range of particle sizes. 12in Sieves also have an option for an Intermediate Height Frame. The selection of frame diameter and height is based on specimen volume and particle size.

Please note that 6in, 10in, and 18in ASTM Test Sieves are nonreturnable.

• Sieve Verification Services are provided. Each sieve is serial numbered and supplied with a certificate of manufacturing conformance in accordance with the latest revisions to ASTM E11 and AASHTO M 92 requirements. Sieves are supplied as Compliance Grade but can be upgraded to Inspection or Calibration Grades through Gilson Verification Services when documentation of greater accuracy is required. Sieves with backing cloth cannot be verified.
• Master-Matched Sieves are another optional upgrade for 8in stainless steel or combination sieves from No. 8 (2.36mm) to No. 325 (45μm). Master-Matched Sieves are verified to meet ASTM E11, then performance-tested to correlate with a master sieve or set of sieves held in Gilson’s reference laboratory. The upgrade assures uniformity for multiple sieve sets in use at different locations. To upgrade from Compliance to Inspection/Calibration Grade or for Master-Matched Services, select from the Sieve Verification drop-down menu when ordering.
• Backing Cloth is an add-on purchase option to prevent sagging or tearing and improves service life for finer mesh sieves. A No.35 stainless steel mesh reinforcement is added to the test sieve below the primary sieve cloth, increasing the strength of the primary sieve cloth and reducing distortion of the openings during use. Backing Cloth is available at an extra cost for sieves with stainless steel mesh finer than No.70 (212µm) on 8in or 12in diameter framed sieves. When ordering, these specially made sieves can be found with a "BU" suffix in the model number. These sieves are made-to-order and are non-returnable. To specify with other diameters, please contact Customer Service.
