a) Dimensional Accuracy : Dimensional tolerances are
maintained as per DIN 40685 fine or coarse tolerances as per
customers specification. wherever necessary final products are
machined/ground to the required tolerances.
b) Routine physical tests - In house routine physical tests
are carried for all the batches for porosity by water
absorption, bulk density, comprehensive strength/breaking load
and bursting strength.
c) Chemical analysis - Carried out every six month by
recognized test houses or by Central Glass and Ceramic
d) Special tests for electrical and electromechanical tests
etc are done by National test houses or by IRDA.
