Test Sieves - Definitions and criteria

 
 

General Information about Analytical Sieves

For a complete list of of sieves available, visit our web site http:/www.test-sieve.com.

Analytical Sieves (Screens) are defined by 4 criteria:

    1. Nominal Sieve Opening for wire cloth also called Mesh Size

    2. Diameter of Sieve

    3. Height of Frame

    4. Material for Frame and Cloth


1. Nominal Sieve Opening

This means the ASTM E-11 or ISO 3310-1 standards.
  • ASTM E-11 standard (American Society for Testing Materials)

    This is the standard most widely used in North America.
  • The opening is defined by a number (number 635 (20 µm) to number 3-1/2 (5.6 mm)), or
    in inches (1/4 in. (6.3 mm) to 5 in. (125 mm)).

    Note: WS Tyler™ had already standardized their sieves before ASTM, so in some cases, the WS Tyler™ number might be different than the ASTM number.
     
  • ISO 3310-1 standard (International Standards Organization)

    This is the standard used in Canada in the field of construction materials.
  • The opening is defined in micrometres (20 µm to 37,500 µm).

2. Diameter

Sieves that conform to current ASTM E-11 standards, have a diameter of 8", 12" and 3".
The 6", 10" and 18" diameters are also available by special order.

Sieves that conform to ISO 3310-1 standards are offered with a 200 mm diameter, and more rarely 400 mm.


3. Height

Analytical Sieves are generally available in 3 heights (see table below):
  • FH = Full Height
  • HH = Half Height
  • IH = Intermediate Height
 
Diameter 8" FH 8" HH 12" FH 12" HH 12" IH 3" FH 3" HH 200mm FH 200mm HH
Overall Height 2-5/8" 1-5/8" 4-1/4" 2-5/8" 3" 1-3/4" 1-1/4" 2-5/8" 1-5/8"
Depth to Cloth 2" 1" 3-1/4" 1-5/8" 2" 1-1/4" 5/8" 2" 1"


4.   Material

Sieves are generally available in 3 material combinations:
  • Brass Frame and Brass screen (cloth)
  • Brass Frame and Stainless Steel screen/cloth
  • Stainless Steel Frame and SS screen
