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:
