Scope

This document describes the method for determining fiber length in glass-fiber-reinforced
plastic products.
This document is applicable to discontinuous glass-fiber-reinforced thermoplastic molding
compounds and molded parts. Before molding, the fiber length is less than or equal to 7.5 mm;
after molding, the fiber length is less than 1 mm.
NOTE: fiber-reinforced polymer matrix composites of other lengths may take this as a reference.
