Description (English):

This document specifies a method for the determination of the size distribution of particulate biofuels by the horizontally oscillating screen method. It applies to particulate uncompressed fuels with a nominal top size of 3,15 mm and above, e.g. wood chips, hog fuel, olive stones. The method is intended to characterize material up to a particle size class (P) of P63. For larger P-classes and PL-classes, the characterization is mainly done by hand sorting. NOTE The definitions and specifications of P- and PL-classes are given in ISO 17225-1, ISO 17225-4 and ISO 17225-9.

Abstract

Overview

EN ISO 17827-1:2024 - Solid biofuels: Determination of particle size distribution for uncompressed fuels - Part 1 describes the oscillating screen method using sieves with apertures of 3,15 mm and above (ISO 17827-1:2024). The standard specifies how to measure particle size distribution of uncompressed biofuels (e.g., wood chips, hog fuel, olive stones) using horizontally oscillating sieves. It is intended to characterize material up to particle size class P63; larger P- and PL-classes are mainly assessed by hand sorting.

Key topics and technical requirements

Scope and applicability: Applies to particulate uncompressed fuels with nominal top size ≥ 3,15 mm. Method complements Part 2 (vibrating screen method for apertures ≤ 3,15 mm).
Principle: Mechanical separation of a test portion into size fractions by a set of horizontally oscillating sieves.
Apparatus: Requirements for sieves (round perforated metal plate per ISO 3310‑2), minimum effective sieve area (example: 1 200 cm² / 400 mm diameter), collecting pan, weighing containers, mechanical sieving equipment and balance.
Sample preparation: Guidance on sample size, subsampling and moisture conditioning (references ISO 14780, ISO 18134 series).
Procedure and calculation: Steps for sieving, mass fraction determination (sieve fractions), and reporting results; revised result table format in the 2024 edition.
Recent technical revisions: Second edition updates include removal of the 8 mm sieve from the set, optional selection of minimum sieving time based on pre‑tests, updated tables and editorial changes. Precision requirements and median-value annex were removed.

Applications and practical value

Quality control: Biomass producers and suppliers use the method to verify compliance with grade specifications and P‑class requirements (see ISO 17225 series).
Fuel handling & logistics: Particle size distribution informs transport, conveying, and storage design to prevent bridging, blockages and ensure consistent bulk density.
Combustion system performance: Boiler and plant operators use size distribution data to optimize feed systems and combustion behavior, minimizing clogging and unsteady combustion.
Safety & health: Identification of fines (including very fine fractions relevant to dust explosion risk and health concerns
