Additional Information; Gilson Test Sieves - Gilson SS-20 Operating Manual

9.1 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 best
choice where contamination, sanitation or extreme wear is
an issue.
