Standards & Technical Specifications

 

Standards relating to solid biofuels

Over the last 10 years a comprehensive suite of standards relating to solid biofuels has been developed by the CEN Technical Committee TC335 Solid Biofuels. These standards include many aspects of solid biomass, from terminology to physical and chemical properties. They also include quality requirements for fuel for smaller boilers as well as for quality assurance. All these standards have an EN number for European Norm.

Copyright on standards is strictly enforced, so standards are available only from an official standardisation body, which in Ireland is NSAI).

A few years ago, work on producing and updating the European standards to worldwide standards within ISO started in the technical committee TC238. Since the European standards were taken as the basis for the ISO standards, work is progressing much more rapidly than if the standards had to be formulated from scratch. Already the first standards have been published.

Since these ISO standards have been produced under the so-called Vienna Agreement, they automatically also become European standards, so they get the designation EN ISO. As such these standards then replace the existing European standards, so for example the EN 16964 Solid Biofuels, Requirements and classes has been replaced this year by the EN ISO 17225.

Within the next few years most of the EN standards on Solid Biofuels will be replaced by EN ISO standards.

The development of a standard goes through several steps to ensure that the contents are alright and that a majority of the participating countries in ISO accept the standard.
The steps are called:

  • Working Document (WD). A document which is being prepared by experts within a particular working group. This document is discussed in the working group until a consensus is reached. It is restricted to members of the working group
  • Committee Draft (CD): this is the final version of the working document that goes for ballot to the countries participating in the drafting. It is not available to the general public.
  • Draft International Standard (DIS or prEN): this version goes for ballot to a much wider circle. Comments may be given on the technical content as well as editorial comments. It is not available to the general public
  • Final Draft International Standard (FDIS or FprEN). This is a document with the widest circulation in ISO member states. Only editorial comments can be made. It is not available to the general public.
  • EN ISO standard, the published version of standard, available to the general public. It is published in English, French and German and may be translated into the national language by the national standardisation body. Where there are disputes; the English version takes precedence.

Below is a list of published and upcoming standards within TC335 and TC238 Solid Biofuels. Check the homepage of NSAI if the particular standard you are interested in has already been published.
