This document specifies a method for determination of the mechanical durability of briquettes. 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

Key Topics

Scope and Purpose: The standard defines a test method to quantify the mechanical durability of compressed biomass briquettes. Durability reflects briquette quality related to their resistance to breakage under mechanical stresses during transport and handling.
Test Principle: Samples of briquettes are rotated inside a cylindrical steel drum (durabilimeter), where they collide and rub against each other and drum walls. After a specified number of rotations at a controlled speed (21 rpm for 5 minutes), the sample is sieved to separate broken particles. The mechanical durability is calculated as the mass percentage of intact briquettes remaining.
Equipment Specifications:
- Durabilimeter drum: Cylindrical steel drum with 600 mm diameter and length, featuring an internal deflector.
- Sieve (Sieve circle): Circular sieve with 5.6 mm diameter round holes for manual sieving, complying with ISO 3310-2.
- Balance: Precision balance with at least 0.1 g accuracy and 2 kg capacity to weigh samples precisely.
- Additional accessories include a dust-tight cover for the drum and sample preparation tools.
Sample Preparation:
- Samples must be representative and meet size and weight requirements based on briquette type (A, B, or C).
- Moisture content must be measured as it influences mechanical durability, following ISO 18134 methods.
- Samples are conditioned to ambient temperature and stored airtight before testing.
Test Procedure:
- Select and weigh test samples as per classification.
- Rotate samples inside the durabilimeter at 21±0.1 rpm for 5 minutes.
- Sieve the contents manually to remove fines and broken particles.
- Calculate the mechanical durability based on the weight ratio of remaining briquettes.
Reporting:
- The test report must include moisture content, sample description, appearance of briquettes before and after testing, test parameters, and calculated durability results.

Applications

ISO 17831-2:2025 is essential for producers, suppliers, and users of solid biofuel briquettes aiming to:

Ensure Quality Control: Implementing this standardized durability test enables manufacturers to assess and improve briquette quality, reducing fines production and waste.
Optimize Handling and Transportation: Durable briquettes withstand mechanical stresses during transport, minimizing losses and contamination, thus maintaining energy density and combustion efficiency.
Support Compliance and Certification: This standard aligns with broader biomass fuel quality standards like ISO 17225, helping stakeholders comply with national and international regulations and market requirements.
Research and Development: Provides a benchmark method to evaluate the effects of raw materials, binders, and production techniques on briquette mechanical performance.
