Standards relating to solid biofuels
The fast way to develop a standard is by creating first a Technical Specification (TS). The TS is then used in practice and comments are collected. Within 5 years of the publication of the TS, it has to be revised and updated to become a full European Norm (EN) or has to be discarded.
At the national standardisation bodies, in the case of Ireland, the NSAI, one can buy the latest published version of a standard. This is a bit of a bother, because often TS’s are being revised and radically changed, but until they have been published as a full blown European Norm, it is only possible to obtain the outdated Technical Specification.
Nearly all the TS in the list below have been updated to draft EN standards, most are in the so-called balloting process where the 39 member countries vote on whether they can accept the standard or not. If the large majority of the countries vote in favor, the standard is accepted. Even when the standard is accepted several months will pass because the standard English text will have to be translated at least in German and French. The three main language versions are published on the same occasion.
In the lists below first the published standards are given. Note that the full European Norms are at the bottom of the first list. In the second list the standards that are being updated or developed are listed. Those with FprEn are almost ready to be published.
Please refer to the National Standards Authority of Ireland (NSAI) for comprehensive list of standards: www.standards.ie . Here one can also order all published standards.
