8.0 ADDITIONAL INFORMATION:

8.1 Gilson Test Sieves

Gilson stocks the widest range and largest quantity of
sieves of any major supplier. Immediate shipment is
available for all popular sizes. Custom sieves with special
diameters and stacking heights are also available.
ASTM Sieves meet the requirements of ASTM E 11. ISO
Sieves meet ISO 565 specifications with tolerances to
ISO 3310-1. All are serial numbered and supplied with a
certificate of manufacturing conformance.
ASTM and ISO Test Sieves are categorized in three
different classes.
• Compliance Test Sieves are supplied with a basic
certificate of manufacturing conformance. All Gilson Test
Sieves meet Compliance grade requirements.
• Inspection Test Sieves have a specified number of
openings measured and reported for each sieve.
• Calibration Test Sieves have two to three times as
many openings measured on each sieve, and are
supplied with more detailed documentation.
Mesh Opening
Opening Sizes are listed using standard millimeter (mm)
or micrometer (µm) descriptions, as well as traditional
inch and number designations where appropriate. Gilson
offers all mesh sizes, but not all sizes are available in

every frame diameter. Common coarse sizes are also
listed. Normally, every second or fourth size is used,
although precision testing may require consecutive sizes.
Additional sieves are often inserted into the sequence to
avoid overloading of individual sieves or to better define
a particular size range.
ISO Sieve Cloth can be mounted in 8in (203mm) frames
when special-ordered. These items are nonreturnable
when supplied as ordered.
Frame Diameter
Frames should accommodate the entire sample volume
with enough surface area to avoid overloading individual
sieves. The diameter selected must also fit the sieve
shaker being used. Gilson stocks most common sizes.
Inquire for custom sizes.
Frame Height
Sieve frames are designated as Full-Height or Half-
Height. Intermediate-Height sieves are also available
for 3in and 12in diameters. Half or Intermediate-Height
frames allow a greater number of sieves to be used when
stack height is limited. Full-Height frames allow free
movement of larger particles during agitation for more
efficient separation. ISO Test Sieves are fitted with black
rubber O-Rings.
Frame and Cloth Material
• Stainless Steel Frame with Stainless Steel Cloth assures
a sieve with the longest possible service life. This is the
