IS :460 (Par t-I, II) 1978
Test Sieves is a common laboratory requirement. Sieves are used for
sieving of chemical powders, medical powders, aggregate, sand soil
and cement etc.
These sieves are manufactured as per various standards like IS, BS,
ASTM, DIN etc. In Civil Engineering it is a common practice to use
sieves for gradation and particle size determination. Manufacturers
brass frame and G.I. Frames Sieves of dia. 200mm, 300mm and
450mm. Normally brass sieves are manufactured in 200cm dia. and
frame is spun brass, The Sieve cloth used is standard SS or prosper
bronze wire mush.
The G.I. Frames sieves manufactured normally n sizes 300mm dia. or
450mm dia. have a steel perforated sheet having accurately
punched square holes.
