IEC 60641-3-1:2008 gives the requirements for pressboard for electrical purposes comprised of 100 % sulphate wood pulp or a mixture of sulphate wood pulp and cotton.

The main changes with respect to the previous edition are:

  • Requirements for types B.0.3 and B.5.3 were added;
  • The precompressed type B.3.1 was divided in B.3.1A and B.3.1B (higher flexibility);
  • Types B.6.1 has been replaced with a new type, but the designation has been kept;
  • Type B.7.1 has been deleted;
  • The thickness relation of the properties has been simplified; and
  • The values were adjusted to today's needs of users.
