What is Standard Test Sieve ?

Standard test sieve, also called test sieving machine or called analysis sieve. Standard test sieve is a kind of instrument used to measure the particle size, it consists of a woven wire mesh with square holes, mainly used in the laboratory for powder, bulk particles and suspensions for classification and particle size determination, it is widely used in food, building materials, metallurgy, agricultural research, chemical industry, pharmaceuticals and many other fields. Now I will take you to understand all aspects of the standard test sieve.

The structure of standard test sieve

Sieve mesh: the sieve mesh is the more technical part of the test sieve sieve. The most commonly used mesh type is stainless steel woven wire mesh. Opening sizes range from 5 inches (125 mm) to 635 mesh (20 microns).

Sieve Frame: the frame is the circular metal ring that holds the mesh in place. Standard frame sizes in the United States are 3 inches, 8 inches and 12 inches. Internationally, 100mm, 200mm and 300mm are standard sizes. Screen frames can be made of stainless steel or brass.

Our standard test sieves are strictly manufactured in accordance with ASTM E11 (American Standard) and ISO 3310-1 (International Standard) specifications. The frames feature a seamless design to prevent sample entrapment and cross-contamination during laboratory analysis.

Skirt: the main purpose of the skirt is to allow the sieves to be stacked without tipping over.

Models of standard test sieves

The common frame diameters of standard test sieves are 75mm, 100mm, 200mm, 300mm and 400mm, which are divided into woven wire mesh test sieves (mesh size of 0.02mm-2.36mm) and perforated metal plate test sieves (mesh size of 1mm-125mm).

Frame Diameter	Mesh Type	Aperture Range (Mesh Size)	Standard Compliant
75mm / 100mm / 200mm	Woven Wire Mesh (Stainless Steel)	0.02 mm – 2.36 mm (635 mesh to 8 mesh)	ISO 3310-1 / ASTM E11
300mm / 400mm	Perforated Metal Plate	1.00 mm – 125 mm	ISO 3310-2 / ASTM E323

Purpose of standard test sieves

Standard test sieves are mainly used for assessing the material particles’ The standard test sieve is mainly used to assess the particle size and distribution characteristics of the material particles, which can meet the relevant standards or process requirements. The purpose of a standard test sieve is as follows:

Particle analysis: The range of particle sizes is determined by using different mesh sizes of the standard test sieve. The material is placed on the sieve mesh of the standard test sieve, and the analysis of particles is completed according to the passage or retention of particles on the sieve mesh of different apertures.

Particle Size Distribution: Analyse the proportion of particles retained in the various layers of the standard test sieve, and generate cumulative percentage curves or particle size distribution curves.

Quality control: from the standard test sieve screening results to verify whether the material meets the preset particle size standards, detect the characteristics of the particles, to complete the optimisation of the production process and product quality control.

Uses of standard test sieves

Standard test sieves are used in a variety of industries for particle analysis. Sometimes the particles are very fine, as in the food or pharmaceutical industry, and sometimes they can be much larger, e.g. in agriculture and mining, where samples of different sizes are separated through a stack of different sizes of sieves, either individually or in stacks of up to 8 layers. With the help of standard test sieves, solid particle sizes from 125 mm to 20 μm can be measured quickly and efficiently.

FAQs

While both standards regulate standard test sieves, ASTM E11 is the American standard utilizing inches for nominal frame diameters (e.g., 8-inch, 12-inch) and specific wire cloth designations. ISO 3310-1 is the international standard, which uses metric measurements (e.g., 200mm, 300mm) for frame diameters. Sanyuantang provides test sieves certified to both standards, ensuring international traceability for laboratory particle analysis.

The choice depends on your sample volume and sieve shaker capacity. Full-height sieves (typically 2 inches or 50mm depth to cloth) allow larger sample volumes and free movement of larger particles without overflowing. Half-height sieves (typically 1 inch or 25mm depth to cloth) are ideal when stacking a larger number of sieves (more than 8 layers) on a shaker with height limitations, or when testing precious, small-volume powder samples.

Sieve calibration drift is primarily caused by wire mesh elongation, mechanical wear from abrasive materials, or improper ultrasonic cleaning. For strict quality control (such as in pharmaceutical or aerospace industries), standard test sieves should be verified every 6 to 12 months using glass microsphere calibration beads or an optical calibration system to ensure the aperture tolerances still comply with ASTM E11/ISO 3310.

Yes, standard test sieves can be used for wet sieving when the sample is ultra-fine, tends to agglomerate, or carries static electricity. However, the sieve frame and mesh must be made of high-grade stainless steel (SUS304 or SUS316) to resist corrosion. For wet testing, a nesting sealing gasket and a specialized wet-sieving lid with spray nozzles are required to wash the fine particles through the mesh without leakage.

For traditional dry powder screening on a standard mechanical sieve shaker, the practical lower limit is typically 45 microns (325 mesh). For particles finer than 45μm down to 20 microns (635 mesh), air-jet sieving or ultrasonic-assisted sieve shakers are highly recommended, as electrostatic charges and surface tension cause fine particles to blind or block the mesh openings during standard dry tapping.

Mixing a brass frame with stainless steel wire mesh in humid environments can trigger galvanic corrosion (bimetallic corrosion). Because brass and stainless steel are dissimilar metals, moisture acts as an electrolyte, accelerating the degradation of the joint where the mesh is soldered or welded to the frame. For maximum durability and precise tensioning, choosing a fully stainless steel (both frame and mesh) standard test sieve is the industry best practice.
