What Is Standard Test Sieve?

Standard test sieve is a specialized tool used in particle size analysis to determine the particle size distribution of a sample. It is a flat, circular sieve with uniform mesh openings of specific sizes, constructed from durable materials such as stainless steel or brass.

product description

Standard test sieves are available in various mesh sizes, typically ranging from coarse to fine, and are used in laboratories for classification and particle size determination of powders, bulk granules and suspensions. With the help of standard test sieves, solid particle sizes from 125mm to 20μm can be measured quickly and efficiently.

Types of Standard Test Sieve

There are several types of standard test sieves available, each designed for a specific testing application. Some common types of standard test sieves include:

Types of Standard Test Sieve

1. Brass Frame Test Sieves: These sieves are made of brass frame and stainless steel mesh screen. They are commonly used for particle size analysis of materials in the construction industry, such as aggregates and concrete.

2. Stainless steel frame test sieve: This type of sieve has a stainless steel frame and mesh screen, and is often used for particle size analysis of powdery and granular materials in pharmaceutical, food processing, chemical and other industries.

3. Nylon Frame Test Sieve: This sieve has a nylon frame and mesh screen and is used for particle size analysis of fine powders and materials that may be damaged by metal sieves.

4. Wire Woven Mesh Test Sieve: widely used, low cost, only square mesh, mesh size from 2.36 mm to 0.02 mm.

5. Metal Perforated Plate Test Sieve: mainly used for large mesh, there are two types of mesh holes, round hole and square hole, the mesh size is from 0.2 to several hundred millimeters, the mesh precision is uniform, and it is not easy to deform.It is mainly used for the detection of large particles.

6. Electroforming Test Sieve: It is mainly used in high-precision occasions, and each mesh can be within the average error range, and the theoretical accuracy can reach one micron.

How Does Standard Test Sieve Works?

Standard test sieves separate particles according to particle size. A sieve consists of a circular frame made of metal or plastic with a mesh screen in the middle. Screens are made of wire weave or stainless steel and have uniform openings of specified size.

To use a standard test sieve, place a sample of material on top of the sieve and shake or tap the sieve to allow the smaller particles to pass through the mesh and collect in a container placed below. Larger particles are retained at the top of the sieve and weighed to determine the percentage of material in each size range.

The pore size of the sieve determines the particle size range that can pass through the sieve. For example, a screen with a mesh size of 100 will allow particles smaller than 100 microns to pass through while retaining particles larger than 100 microns at the top of the screen.

1. Mesh number: refers to the size of the mesh holes, which is the main feature to distinguish different types of sieves. Mesh size is measured in microns or millimeters and ranges from very fine to coarse.

2. Frame Material: Can be made from a variety of materials including stainless steel, brass or plastic. The frame material affects the durability and corrosion resistance of the screen.

3. Screen material: It can be made of various materials, including wire mesh, stainless steel or nylon. The screen material affects the accuracy, durability and corrosion resistance of the screen.

4. Diameter: Diameter refers to the size of the circle frame, from small to large. The diameter of the sieve is usually selected according to the amount of material being tested and the testing equipment used.

5. Height: refers to the distance from the top of the screen frame to the bottom of the screen. Height affects the amount of material that can be loaded onto the screen and the accuracy of particle size analysis.

6. Certification: Some standard test sieves may be certified to specific industry standards, such as ASTM or ISO, to ensure consistent mesh size and tolerances for each sieve. Certification can provide additional assurance of accuracy and reliability.
