IS 13411 : 1992 Glass reinforced polyester dough moulding compounds (DMC)

1 Scope

1.1 This standard specifies requirements for themosettingpolyester dough moulding compounds which are classified accordingto their electrical and mechanical properties and which are usedfor processing by moulding-transfer, compression and injection.

1.2 Compounds whose fibrous reinforcement include glass, otherthan E-glass, are excluded in this standard.
