British Standard 61212 details

TUFNOL Technical information

British Standard BS EN 61212 explained.

The current British Standard for round laminated tubes and rods is:

BS EN 61212. Industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes.

BS EN 61212 is identical in content to the internationally recognised standard IEC 61212. It is published in a number of separate parts, as listed below. Part 3 is also divided into several ‘sheets’.

BS EN 61212-1

General requirements

BS EN 61212-2

Methods of test

BS EN 61212-3-1

Specifications for individual materials. Round laminated rolled tubes

BS EN 61212-3-2

Specifications for individual materials. Round laminated moulded tubes

BS EN 61212-3-3

Specifications for individual materials. Round laminated moulded rods

 Individual grades are detailed in Sheets 1 to 3 of Part 3. The different types are easier to follow, when the abbreviations used 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

SI refers to Silicone resin

MP refers to Mica Paper

So, for example, ‘Type EP GC 21’ 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.
