Description (English):

This document specifies a method for determination of the mechanical durability of pellets. The mechanical durability is a measure of the resistance of compressed fuels towards shocks and/or abrasion as a consequence of handling and transportation.

Abstract

Overview

ISO 17831-1:2025 - Solid biofuels: Determination of mechanical durability of pellets (Part 1: Pellets) defines a standardized laboratory method to measure the mechanical durability of compressed biomass pellets. Mechanical durability quantifies a pellet’s resistance to shocks and abrasion during handling and transport by tumbling a test portion, sieving out generated fines, and reporting the proportion of material retained.

Key topics and requirements

Scope: Method for pellets (typically ≤ 25 mm diameter); part of the ISO 17831 series for solid biofuels.
Test principle: Tumbling in a rotating, dust-tight pellet tester with internal baffle to induce collisions; subsequent sieving to remove fines
