Defines a procedure for determining the gel time of prepregs made from continuous reinforcement impregnated with epoxy and/or unsaturated-polyester resin. Applies to most prepregs having a width between 300 mm and 1 000 mm. Not intended for very narrow prepregs, eg narrow tape, or for those having a low resin content.

This International Standard specifies a method for the determination of the gel time of prepregs made of continuous reinforcement impregnated with epoxy and/or unsaturated-polyester resin.

The method is applicable to most prepregs with a width in the range 300mm to 1000mm.

It is not suitable for very narrow prepregs (for example narrow tape), nor for prepregs with a low resin content.

NOTE Other methods of measuring gel time exist. These methods are based on principles which differ from those described in clause4, and the results obtained using such methods may be different from those obtained with this International Standard. The method described below is the traditionally used one and is widely accepted, even though it may be somewhat obsolete.
