Tufnol Technical information

British Standard BS EN 60893 explained.

The current British Standard for laminated sheets is:

BS EN 60893 Insulating materials. Industrial rigid laminated sheets based on thermosetting resins for electrical purposes.

BS EN 60893 is identical in content to the internationally recognised standard IEC 60893. It is published in a number of separate parts, as listed below. Part 3 is also divided into several ‘sheets’.

- Technical Report


More than 40 different types of laminate are defined and these individual grades are detailed in Sheets 2 to 7 of Part 3.
The different types are easier to follow, when the abbreviations are understood. They are:

EP refers to Epoxy resin

CC refers to Cotton Cloth

MF refers to Melamine resin

CP refers to Cellulosic Paper
(made from wood or cotton fibres)

PF refers to Phenolic resin

GC refers to woven Glass Cloth

UP refers to Unsaturated Polyester resin

GM refers to non-woven Glass Mat

SI refers to Silicone resin

PC refers to woven Polyester-fibre Cloth

PI refers to Polyimide resin

WV refers to Wood Veneers

 

CR refers to Combination Reinforcements (i.e. those containing more than one type of reinforcement

So, for example, ‘Type EP GC 201’ refers to an epoxy resin bonded glass fabric grade. The numbers are used simply to distinguish between the types.

Tufnol offers grades against many of the types specified in this standard. However, some types are outside our product range, whilst others are not included as they are not widely used.
