本文件确定了分级非木质颗粒的燃料质量等级和规格。本文件仅涵盖由以下原材料生产的非木质颗粒（见ISO 17225-1:2021，表1）: -2草本生物量 -3.水果生物量 -4水生生物量 -5生物质混合物和混合物 注1:草本生物量来源于具有非木质茎的植物，并在生长季结束时死亡。它包括粮食生产或加工业的谷物或种子作物及其副产品，如谷物。 注2:混合物和混合物包括来自主要来源的固体生物燃料组（木质生物质、草本生物质、水果生物质和水生生物质）的混合物和混合物。 混合物是有意混合的生物燃料，而混合物是无意混合的生物燃料。 混合物和混合物的来源将使用ISO 17225-1:2021表1进行描述。 如果固体生物燃料混合物或混合物含有经过化学处理的材料，则应予以说明。 注3:经热处理的生物质颗粒（例如，经烘烤的颗粒）不包括在本文件的范围内。

This document determines the fuel quality classes and specifications of graded non-woody pellets. This document covers only non-woody pellets produced from the following raw material (see ISO 17225‑1:2021, Table 1): —    2 Herbaceous biomass —    3 Fruit biomass —    4 Aquatic biomass —    5 Biomass blends and mixtures NOTE 1    Herbaceous biomass originates from plants that have a non-woody stem and which die back at the end of the growing season. It includes grains or seeds crops from food production or processing industry and their by-products such as cereals. NOTE 2    Blends and mixtures include blends and mixtures from the main origin-based solid biofuel groups woody biomass, herbaceous biomass, fruit biomass and aquatic biomass. Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The origin of the blend and mixture is to be described using ISO 17225‑1:2021, Table 1. If solid biofuel blend or mixture contains chemically treated material it shall be stated. NOTE 3    Thermally treated biomass pellets (e.g. torrefied pellets) are not included in the scope of this document.
