FOREWORD
This amendment 1 of IEC 60893-3-2 has been prepared by IEC technical committee 15: Solid
electrical insulating materials.
This amendment introduces new/improved limits of CHARPY impact strength and IZOD
impact strength for all types of rigid laminated sheets based on epoxy resins and
new/improved limits of breakdown voltage to all EP GC types and a new/improved limit of
flexural strength for the EP PC 301 and a new limit of proof tracking index for the EP GC 306
type. This amendment also introduces new types of rigid laminated sheets based on epoxy
resins.
The text of this amendment is based on the following documents:

Table 1 – Types of industrial rigid laminated sheets based on epoxy resins
Below type designation EP GC 308, add the following new designations:

EP GC 309 Similar to EP GC 201, but with defined mechanical strength
at elevated temperature
310 Similar to EP GC 202, but with halogen free compound
311 Similar to EP GC 204, but with halogen free compound

Below Table 1, add the following text to the notes:
The definition of halogen free epoxy laminated sheet is given in IEC 61249-2-21:2003:
The maximum total halogens contained in the resin plus reinforcement matrix no greater than
1500 ppm with a maximum chlorine content of 900 ppm and maximum bromine content of 900
ppm. The test method for determination of the halogen content is given in IEC 61189-2:2006.
