标准范围

本文件确定了工业用分级生猪燃料和木屑的燃料质量等级和规格。它仅涵盖由以下原材料生产的猪燃料和木屑（参见ISO？17225-1，表？1）:—？1.1森林、人工林等原木；—？1.2木材加工业的副产品和残留物；—？1.3用过的木材；—？1.4共混物和混合物。本文件涵盖了通过用钝工具如滚筒、锤子或连枷破碎产生的具有不同大小和形状的碎片的生猪燃料，以及木屑，木屑被定义为具有亚矩形形状和典型长度为5？毫米到50？mm通常以通过用锋利工具如刀进行机械处理而产生的具有限定粒度的碎片的形式。参见ISO中的1.1.2？17225-对于木材加工工业的副产品和残留物，可以包括化学处理的材料（如胶合、涂漆、层压），不允许含有高于典型原始材料值或高于原产国典型值的卤化有机化合物或重金属（见ISO？17225-1附录B）。笔记？如果1.4共混物和混合物包括1.3.2化学处理的废木材，则只能在允许使用1.3.2的设施中使用。

This document determines the fuel quality classes and specifications of graded hog fuel and wood chips for industrial use. It covers only hog fuel and wood chips produced from the following raw materials (see ISO 17225-1, Table 1):—    1.1 Forest, plantation and other virgin wood;—    1.2 By-products and residues from wood processing industry;—    1.3 Used wood;—    1.4 Blends and mixtures.This document covers hog fuel that has pieces of varying size and shape, produced by crushing with blunt tools such as rollers, hammers, or flails, and wood chips which are defined as chipped woody biomass with a sub-rectangular shape and a typical length of 5 mm to 50 mm typically in the form of pieces with a defined particle size produced by mechanical treatment with sharp tools such as knives.See 1.1.2 in ISO 17225-1, Table 1 for by-products and residues from wood processing industry, which can include chemically treated material (e.g. glued, painted, laminated), are not allowed to contain halogenated organic compounds or heavy metals at levels higher than those in typical virgin material values or higher than typical values of the country of origin (see Annex B in ISO 17225-1).NOTE       If 1.4 Blends and mixtures includes 1.3.2 Chemically treated used wood, it can be only used in the installations permitted to use 1.3.2.
