Gilson Company, Inc.
Periodic, measurement of opening sizes helps to determine
whether a sieve is still usable. Measurements may be taken
directly, using calipers or an optical comparator, or can
be performance-based, by testing a standard reference
material on the working sieves, as outlined in ASTM E 2427,
Sieve Acceptance by Performance Testing.
Gilson reverification Services can be performed on used
ASTM or ISO Test Sieves. An optical comparator with NIST
traceable calibration measures opening and wire diameter
sizes on each sieve. Certification reports are produced for
the appropriate grade. These services are available for all
ASTM and ISO sieve sizes and types, and are ordered by
specifying model numbers for Inspection Sieve Verification,
or Calibration Sieve Verification. Sieves are not included in
the purchase price. When verifying used sieves, contact
a Gilson customer service representative for shipping
instructions.
Master-Matched Sieves are ASTM woven-wire sieves
from No.8 (2.36mm) to No.325 (45µm) that have been
measured and shown to closely match a set of master
sieves maintained by Gilson in a reference laboratory.
Master-Matched Sieves from Gilson are always matched to
the same master set, assuring that one sieve is very close
to another. Master-Matched Sieves are also certified to
meet ASTM E 11, so additional verification is not normally
necessary. Master-Matching is done using special standard
reference materials, sized for each sieve. Each sieve is
performance tested to insure it yields ±2.5% of the weight
retained value of the master sieve (equivalent to about
±1.25% of sample weight).
Ordering
All Gilson test sieves meet ASTM or ISO requirements for
Compliance Test Sieves. Ordering additional verification
services for each individual sieve upgrades them to meet
Inspection or Calibration specifications.
