DIN EN ISO 17831-2:2016-05

This document has been prepared by Technical Committee ISO/TC 238 "Solid biofuels" in collaboration with Technical Committee CEN/TC 335 "Solid biofuels", the secretariat of which is held by SIS (Sweden). This document aims to define the requirements and method used for testing the mechanical durability of briquettes. It is intended for persons and organisations that manufacture, plan, sell, erect or use machinery, equipment, tools and entire plants related to such briquettes, and to all persons and organisations involved in producing, purchasing, selling and utilising briquettes. The durability is measure of the resistance of densified fuels towards shocks and/or abrasion as a consequence of handling and transportation processes. The test portion is subjected to controlled shocks by collision of briquettes against each other and against the walls of a specified rotating test chamber. The durability is calculated from the mass of the sample remaining after separation of abraded and fine broken particles. The responsible German body is Working Committee NA 062-05-82 AA "Biogene Festbrennstoffe" ("Solid biofuels") at DIN Standards Committee Materials Testing (NMP).
