本技术规范规定了用于测定不规则形状的压缩燃料如颗粒或团块的颗粒密度的方法。它不适用于软或半软粒。 注1术语软颗粒在CEN/TS 15639中定义。 注2:由于有机材料对环境或技术影响（如空气湿度，振动，磨损或生物降解）的敏感性，颗粒密度可能会发生变化。因此，颗粒密度可以在时间期间变化，因此测量值应被视为瞬时燃料性质。 注3:在准备本文件时，在欧洲市场无法确定固体回收燃料的煤块的生产

This Technical Specification specifies a method for the determination of particle density of irregularly shaped pieces of compressed fuels such as pellets or briquettes. It is not applicable to soft or semi-soft pellets. NOTE 1 The term soft pellet is defined in CEN/TS 15639. NOTE 2 Particle density is subject to variation due to the susceptibility of organic material to environmental or technical impacts such as air humidity, vibration, abrasion or biodegradation. Therefore, particle density can vary during time thus the measured values should be regarded as a momentary fuel property. NOTE 3 At the time of preparing this document, the production of briquettes of solid recovered fuels could not be identified in the European market.
