Solid biofuels - Sampling - Methods for preparing sampling plans and sampling certificates
This Technical Specification describes methods for preparing sampling plans and sampling certificates, and is applicable to solid biofuels that are either:
- fine and regularly-shaped particulate materials, particle sizes up to about 10 mm that can be sampled using a scoop or pipe, for example: sawdust, olive stones and wood pellets;
- coarse or irregularly-shaped particulate materials, particle sizes up to about 200 mm that can be sampled using a fork or shovel, for example: wood chips and nut shells, forest residue chips, and loose straw;
- baled materials that require a special sampling tool to be used if the bales are not to be broken open for sampling, for example baled straw or grass;
- large pieces (particles sizes above 200 mm) which are to be picked manually;
- Fibrous and vegetable waste dewatered in belt press.
The methods described in this Technical Specification may be used, for example, when the samples are to be tested for bulk density, durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition, and impurities. The methods are not intended for obtaining the very large samples required for the testing of bridging properties.

This Technical Specification (CEN/TS) was approved by CEN on 19 March 2005 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia,
Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This Technical Specification (CEN/TS 14779:2005) has been prepared by Technical Committee CEN/TC 335
“Solid biofuels”, the secretariat of which is held by SIS.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic,
Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland
and United Kingdom.
Introduction
Biofuels are a major source of renewable energy. Technical Specifications are needed for production, trade
and use of solid biofuels. For sampling and sample preparation of biofuels the following Technical
Specifications can be used:
CEN/TS 14778-1, Solid biofuels - Sampling – Part 1: Methods for sampling
CEN/TS 14778-2, Solid Biofuels - Sampling – Part 2: Methods for sampling particulate material transported in
lorries
CEN/TS 14779, Solid biofuels – Sampling – Methods for preparing sampling plans and sampling certificates
CEN/TS 14780, Solid biofuels - Methods for sample preparation
Current practice and the best available knowledge have been used to write these Technical Specifications.
The results of recent sampling experiments may be used to improve the sampling plans.
These Technical Specifications can be used by production and trading of solid biofuels. They are also useful
for buyers of solid biofuels, regulators, controllers and laboratories.
1 Scope
This Technical Specification describes methods for preparing sampling plans and sampling certificates, and is
applicable to solid biofuels that are either:
fine and regularly-shaped particulate materials, particle sizes up to about 10 mm that can be sampled
using a scoop or pipe, for example: sawdust, olive stones and wood pellets;
coarse or irregularly-shaped particulate materials, particle sizes up to about 200 mm that can be sampled
using a fork or shovel, for example: wood chips and nut shells, forest residue chips, and loose straw;
baled materials that require a special sampling tool to be used if the bales are not to be broken open for
sampling, for example baled straw or grass;
large pieces (particles sizes above 200 mm) which are to be picked manually;
Fibrous and vegetable waste dewatered in belt press.
The methods described in this Technical Specification may be used, for example, when the samples are to be
tested for bulk density, durability, particle size distribution, moisture content, ash content, ash melting
behaviour, calorific value, chemical composition, and impurities. The methods are not intended for obtaining
the very large samples required for the testing of bridging properties.
