ASTM Test Sieves for Laboratory Particle Sizing

Choose the Opening Series Required by the Method

Start with the sieve openings specified by the test procedure, then select the frame and construction. Check both the sieve number and its stated opening dimension on each listing. A sieve number identifies an opening designation; it is not the frame diameter or a statement of the documentation supplied.

This category brings together multiple sieve constructions and accessories. Identify whether the item is a complete sieve, collection pan, cover or service before ordering. Confirm the applicable standard and documentation on the individual listing rather than assuming every item has identical requirements.

Match Diameter and Stack Height

Select frame diameter to suit the required sample handling and the existing shaker or sieve stack. Check the manufacturer's nesting and clamping requirements. A full-height sieve and a half-height sieve provide different working depths; the combined stack, cover and pan must fit the equipment.

One listed example is the Gilson 8in All-Stainless Full-Height No. 200 Sieve, with 75µm openings. Its listing identifies ASTM E11 compliance and includes conformance documentation. Those details apply to that product, not automatically to every construction shown in the category.

Separate Frame Material from Screening Medium

Check the materials used for the frame and the screening surface independently. Brass or stainless construction, transparent frames and specialized media answer different handling and compatibility needs. Choose them using the selected product's specifications and your laboratory's material restrictions.

For specialized particle sizing, compare precision electroformed sieves separately from woven-wire designs. Where a shaker requires a particular transparent-frame configuration, review 3in acrylic frame test sieves and confirm the exact model compatibility.

Complete the Stack with Matching Accessories

Choose a pan and cover that match the frame system. Examples include the Gilson 8in stainless full-height sieve pan and Gilson 8in brass sieve cover. Verify fit and construction for the selected stack; a shared nominal diameter is not a universal compatibility guarantee.

Check whether backing cloth is supplied or represents a separate version. The listed No. 200 example has no backing cloth included, so do not assume a fine-opening sieve arrives with an additional support layer.

Specify Documentation and Ongoing Checks

Confirm the required conformance, inspection or verification documentation before purchase. Use inspection tools for the checks they support and reference materials where the verification method calls for them. If the procedure specifies another opening series or frame system, compare ISO test sieves rather than substituting on size alone.
