Gilson Company, Inc.
7.0 GIlSON 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 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 565 Sieve Cloth can be mounted in 8in (203mm) frames
when special-ordered. These items are non-returnable
when supplied as ordered. Inquire.

overloading individual sieves. The frame diameter selected
must also fit the sieve shaker being used. Most common
sizes are normally in stock. Inquire for custom sizes.
Frame heights 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.

¹ Heights are approximate and vary due to mesh thickness.
Frame and Cloth Material should meet both application
and economic requirements:
• Stainless Steel Frame with Stainless Steel Cloth
assures a sieve with the longest possible service life.
This is the best choice where contamination, sanitation
or extreme wear is an issue.
• Brass Frame with Stainless Steel Cloth is a popular choice
that offers extended service and cost-effectiveness.
• Brass Frame with Brass Cloth is an economical choice
for light-duty applications. Coarse-series sieves are not
available with brass cloth.
backing Cloth can be added to standard sieves with
stainless steel cloth to prevent sagging or tearing of
expensive fine mesh. Unsatisfactory service life from a sieve
would suggest replacement by a sieve built with backing
cloth. To order, add the code "BU" as a suffix to the model
number of the sieve. These sieves are made-to-order, have
longer delivery times and are non-returnable.
