What are Test Sieves
Test sieves are used in many industries including construction, mining and pharmaceuticals to analyse and separate materials by size. A test sieve is made up of a frame, mesh and sieve cloth which work together to classify materials into different sizes. The mesh size and material of the sieve cloth determines the accuracy and efficiency of the sieving process. Knowing the different types of ASTM test sieves, their applications and how they work is key to choosing the right sieve for your needs.
Choosing the Right Sieve
Choosing the right test sieve depends on the material being tested, the particle size range and the level of accuracy required. Consider the following when choosing a test sieve:
-
Material: Stainless steel, brass or plastic frames and mesh are available, each with their own pros and cons.
-
Mesh size: Finer mesh sieves are for smaller particle sizes, coarser mesh sieves for larger particle sizes.
-
Diameter: ASTM test sieves come in various diameters 3, 8 and 12 inches to fit different sample sizes.
-
Frame height: Full height, half height and intermediate height sieve frames are available to suit different particle size ranges.
-
Certification: Look how our sieves comply with ASTM E11 and ISO 3310-1 standards.
ASTM Standards and Compliance
ASTM (American Society for Testing and Materials) standards are key to the accuracy and reliability of ASTM test sieves. ASTM E11 is the standard specification for woven wire test sieve cloth and ASTM test sieves which covers the requirements for sieve cloth, ASTM test sieves and their applications. Compliance with ASTM E11 means test sieves meet the highest level of material separation accuracy. Look for suppliers that supply certified test sieves that comply with ASTM E11 and ISO 3310-1 standards.
Aggregate Test Sieves
When you are sieving with an ASTM E11 aggregate test sieve any method you use must be compliant with ASTM or ISO standards. These standards apply not just to the wire mesh used to filter organic and non-organic specimens but also to the frames that hold and stack them together.

Aggregate test sieves are used in construction, geology, agriculture and even in food and biology. They are used to separate, classify and evaluate various materials from soils and sands to grains and seeds. The efficiency and accuracy of sieve analysis depends on the quality and type of brass frame sieves used. This guide covers ASTM E11 aggregate test sieves, design, applications and materials.
Aggregate Test Sieves
Aggregate test sieves are used to sort materials by size and shape through the process of sieving, where particles are passed through openings in a screening medium, commonly known as woven wire mesh. Sieves are used to determine size distribution in various materials which is necessary for quality control and compliance to industry standards.
Design and Materials Woven Wire Mesh Material: Most modern sieves use stainless steel mesh due to its durability and corrosion resistance. Stainless steel is good for sieving dry ingredients and liquids, it’s very versatile.
Frame Composition: The sieve frames of test sieves are made from stainless steel or brass. Brass frame is less susceptible to magnetic interference and is lighter, stainless steel frame is more durable.
Woven Wire Mesh and Sieve Sizes: Sieves come in different sizes and openings to accommodate various materials and requirements. These openings can range from very fine mesh strainer suitable for flour or sand to larger meshes designed to separate stones or coarse particles.
ASTM Test Sieves Usage in Various Fields
Construction Materials: In construction industry, mesh sieves are used to analyze components like sand and gravel to meet size and shape specifications. This is necessary for making concrete and asphalt with strength and durability.
Agriculture: Brass frame mesh sieves are used to separate seeds by size or remove foreign bodies from harvested grains. This is for both planting and consumption, for purity and uniformity of agricultural products.
Food Industry: In food processing, brass frame mesh sieves can remove contamination and make sure products like flour or spices are free from unwanted particles, for food safety standards.
Geology and Soil Science: Brass frame mesh sieves are used to classify soil and mineral samples, for research and land management decisions. Particle distribution in soils can affect their suitability for various uses, farming or construction.
Biology and Environmental Science: Brass frame mesh sieves are used in biological studies to classify organisms or organic materials by size which is important for ecological assessments and environmental monitoring.
Advantages and Disadvantages of Test Sieves
Advantages Accuracy and Efficiency: Well designed sieves give accurate particle distribution measurements which is important for many industrial applications.
Versatility: With various sieve sizes and materials, users can do many types of separations, from fine powders to larger aggregates.
Traceability: High quality sieves often come with certification for traceability which is necessary for industry standards and quality control.
Disadvantages Maintenance Required: Sieves need to be cleaned and maintained regularly to prevent contamination between samples and to get accurate results.
Wear and Tear: Over time the stainless steel mesh may stretch or the frame may be damaged which can affect the sieving process.
Selecting the Right Sieve
When choosing a sieve consider: Choose a mesh material that is compatible with the sample being sieved to avoid chemical reaction or contamination.
Mesh Size: The size of the woven wire mesh openings should match the size of the material being tested.
Standards Compliance: Make sure the sieve meets the industry standards which vary depending on the field of application.
Maintenance and Care
Proper care and handling of sieves is important to maintain their precision and longevity. Cleaning the mesh regularly to remove all residues and storing sieves in a way that won’t deform the mesh are must do’s. For metallic sieves, avoid exposure to moisture that can cause rust especially if not made of stainless steel.
Conclusion
Aggregate test sieves are versatile tools across many fields, providing critical information for production, quality control and research. By selecting the right sieve for the job, taking care of it and understanding its applications and limitations, professionals can get reliable and actionable results. Whether for construction, agriculture or food safety, the right set of sieves can make a big difference, effortlessly guiding sustainable practices and better product quality.
Maintenance and Accessories
Proper maintenance and accessories are important to ensure the accuracy and longevity of test sieves. Cleaning and inspection of the sieve cloth and frame regularly are necessary to prevent damage and contamination. Accessories like sieve covers, pans and backing cloth can help improve the sieving process. Check out these maintenance and accessories tips:
-
Clean the mesh and frame regularly.
-
Use brass brush for coarser mesh.
-
Use sieve covers and pans.
