EN ISO 14780:2017/A1:2019

Solid biofuels - Sample preparation - Amendment 1 (ISO 14780:2017/Amd 1:2019)

The proposed international standard describes methods for reducing combined samples (or increments) to laboratory
samples - and laboratory samples to sub-samples and general analysis samples and is applicable to solid biofuels.
The methods described in this proposed document may be used for sample preparation, for example, when the
samples are to be tested for calorific value, moisture content, ash content, bulk density, durability, particle size
distribution, ash melting behaviour, chemical composition, and impurities. The methods are not intended to be
applied to the very large samples required for the testing of bridging properties.

Predlagani mednarodni standard opisuje metode za zmanjšanje kombiniranih vzorcev (ali vzorcev) na laboratorijske vzorce in laboratorijskih vzorcev na podvzorce ter splošne analizne vzorce, uporablja pa se tudi za trdna biogoriva. Metode, ki so opisane v tem predlaganem dokumentu, se lahko uporabijo za pripravo vzorcev, ko je potrebno preskusiti na primer kalorično vrednost, vsebnost vlage, vsebnost pepela, prostorninsko maso, odpornost, porazdelitev velikosti delcev, lastnosti pepela pri taljenju, kemično sestavo in nečistoče. Te metode niso namenjene za uporabo pri zelo velikih vzorcih, ki so potrebni za preskušanje premostitvenih lastnosti.

Overview

EN ISO 14780:2017/A1:2019 is an important amendment to the international standard ISO 14780:2017, focusing on the sample preparation of solid biofuels. Published by CEN and approved in September 2019, this amendment refines procedures to ensure accuracy and consistency in preparing solid biofuel samples for testing. As solid biofuels form a critical component of renewable energy sources, standardized sample preparation protocols are essential for reliable quality assessment and regulatory compliance.

This European standard has been adopted across numerous countries in Europe, ensuring alignment in biofuel testing methodologies. The amendment aims to support laboratories, manufacturers, and regulators by incorporating updated steps and clarifications to the sample preparation process.

Key Topics

• Sample Preparation Methodology
  The core of EN ISO 14780:2017/A1:2019 deals with enhancing the procedures used to prepare solid biofuel samples for analysis. This includes guidance on homogenization, size reduction, and sub-sampling techniques to obtain representative and stable samples.

• Flow Sheet Revision
  A critical update introduced by this amendment is the replacement of Figure 5, which outlines the flow sheet for sample preparation and optional extraction of sub-samples. This flow sheet provides a clear, step-by-step process to optimize sample handling and minimize errors.

• Optional Sub-Sample Extraction
  The amendment notes the various optional sub-sample extraction techniques, highlighting that the list of methods is not exhaustive. This flexibility allows laboratories to tailor sample preparation to the characteristics of specific biofuels or analytical requirements.

• Compliance and Harmonization
  EN ISO 14780:2017/A1:2019 mandates that all CEN members standardize their national regulations in line with this amendment by April 2020. This unification supports international trade and improves the reliability of solid biofuel assessments across Europe.

Applications

• Quality Control in Biofuel Production
  Producers of solid biofuels can implement the standardized sample preparation techniques to ensure product consistency and meet customer or regulatory specifications.

• Laboratory Analysis
  Testing laboratories utilize this standard to prepare samples for physical and chemical characterization tests, such as moisture content, calorific value, and ash analysis.

• Regulatory Compliance
  Authorities and certification bodies depend on EN ISO 14780:2017/A1:2019 for establishing testing protocols that comply with environmental and trade regulations related to renewable energy sources.

• Research and Development
  Scientists studying solid biofuels can apply the standard’s sample preparation methods to conduct accurate and reproducible experiments, facilitating innovation in bioenergy technologies.

• ISO TC 238 Technical Committee – The committee responsible for standards on solid biofuels, covering sampling, testing, and methods.
• EN ISO 18134-2 – Determination of moisture content in solid biofuels.
• CEN/TC 335 Documents – European standards harmonizing biofuel testing and sustainability requirements.

By adhering to EN ISO 14780:2017/A1:2019, stakeholders across the solid biofuels supply chain ensure high-quality, comparable data supporting the broader adoption and commercialization of renewable solid biofuel resources. This amendment is a key element in advancing sustainable energy solutions worldwide.
