Sieve /ตะแกรง

AASHTO M92 is a specification often used by state or federal transportation agencies and closely follows ASTM E11. Test Sieves meeting these specifications are supplied in Compliance Grade; serial numbered and supplied with a certificate of manufacturing conformance.

For applications where documented accuracy is required, Compliance Grade sieves can be upgraded to Inspection or Calibration Grades by adding the appropriate Gilson Verification Service to your order.

ASTM Test Sieves – Available in all mesh sizes, with frames and mesh constructed of stainless steel, brass or combination brass frame and stainless steel cloth, these sieves meet ASTM E11 and AASHTO M92 requirements. Selection of frame diameter and full or half-height configuration is based on specimen volume and particle size.
ASTM Supplemental Sieves – ASTM E11 incorporates a new range of opening sizes for test sieves (supplemental sizes), intended to supplement existing sizes. Gilson is offering these Metric Alternative sizes in stainless steel cloth installed in conventional 3in, 8in, and 12in diameter stainless steel frames.
ISO Test Sieves – ISO Test Sieves are based on SI, or metric dimensions, with 200mm or 300mm diameter and all ISO mesh sizes available. These sieves meet ISO 565 and 3310-1 specifications. They are constructed of stainless steel frame and mesh or brass frame with stainless steel mesh, and come in full- or half-height sizes.
Wet-Wash Sieves – Wet-Wash Sieves feature durable extra-deep brass or stainless steel frames to contain wash water, avoid sample loss and allow accurate and efficient preparation and testing of materials. Some models are designed with interchangeable screens and discs that are easily replaceable for extended service life. The Elutriation Sieve is a unique design, well suited for washing samples with high fines contents.
