What is a test sieve?

A test sieve is a screening medium, with openings of uniform size and shape, mounted on a rigid frame. To put it simply, a test sieve is a tool that uses metal cloth with holes in it to separate some kind of particles from materials. A test sieve consists of a screen (often wire mesh) held in a round metal frame and come in many different sizes and specs. In most cases, the exact test sieve you need is specified by your industry standard.

What is a test sieve used for?

Test sieves are used in all kinds of industries to perform particle analysis. Sometimes the particles are super fine, like in the food or pharmaceutical industry. Sometimes the particles can be larger, like in the agricultural and mining industry.

Nonetheless, test sieves can be used individually or several can be stacked on top of each other in a sieve shaker. A sieve shaker is a machine that uses some type of agitation to separate the particles down through a stack of different sized sieves. This gives the user a different size sample in each sieve.

Types of test sieve

There are two types of sieves: dry test sieves and wet wash test sieves.

Dry test sieves are used when the particles are free-flowing and can pass through openings with just a shaking or tapping motion.

Wet Wash Test Sieves are used when water needs to be added to the sample to get the particles to pass through the sieve.

Wet wash sieving is often used in the aggregate industry. Clay and silt sticks to the outside of the rocks making them larger than they really are. By adding water to their sieving process, the dirt and silt are cleaned off the outside of the rocks allowing them to be measured properly.

What are test sieve standards?

One of the most important things to understand when it comes to test sieves are the industry standards. You have to know your industry standards to purchase the correct test sieve. Here's a link to find your industry standards

Your Industry standards will tell you:

  1. Your required mesh size
  2. How many test sieves you need
  3. How much sample to use
  4. If you need to use a sieve shaker
  5. How long you need to run your sample for
  6. If you need your sieves certified/calibrated


Test Sieve standards relate to the construction of the sieve itself as well as the performance of the sieve.

W.S. Tyler actually developed the very first test sieve standard over 100 years ago, but there are now two types of standards that are most commonly used: ISO 3310-1 and ASTM E11.

Typically, ISO Standards are international standards. ASTM are the North American standards.

In simpler terms, your standards depend on the material being tested and the industry you are in.
