General Information
Use of Sieves
Wherever solid materials are handled or
processed, test sieves find application. In
laboratory or
plant these simple precision
instruments are invaluable.
Test sieves are used, for example, by chemists
and pharmacists, physicists and geologists,
chemical
and civil engineers, mining and
metallurgical engineers.
The uses to which test sieves are put are as
many and varied as the types of people who
use
them. Most solid raw materials and
finished product specifications contain a clause which
stipulates the range of the size
spread or the maximum or minimum size in terms of some
standard sieve series
Some typical applications are as follows: the sizing of chemical and pharmaceutical crystals
and
powders; the grading of coal and ores; determining the efficiency of a crusher; grinder or
industrial
screening unit; cement testing; classifying silt, soil, sand, gravel and other materials
encountered in
civil engineering work; checking the state of a fluidised catalyst in an oil
refinery.
Test Sieves Available from Endecotts
Laboratory Test Sieves
All test sieves manufactured to a National or International Specification are supplied with a
Certificate of Compliance, and are individually serial numbered giving full traceability.
Calibrated Test Sieves
Test sieves inspected and calibrated in accordance of ISO 3310 (BS:410). Each sieve is supplied
with a Calibration Certificate recording the number of apertures and wire diameters measured, the
average aperture size and
standard deviation separately for the warp and weft directions. The type
of weave will also be stated.
Re-Examination Service
Used sieves are examined and inspected in accordance with the appropriate specification.
Complying sieves are issued with a Compliance, Inspection or Calibration Certificate, as
requested by the customer.
