标准范围

本文件规定了往复式内燃机（RIC发动机）气体和颗粒废气排放的现场测量和评估方法。当需要在现场测量非道路机械、工业设备、海上设施、发电机组、柴油轨道牵引或类似机械应用中使用的RIC发动机的排放时，本文件适用。第4条适用于在单个工作点进行离散模式稳态气体或颗粒排放测量，或在现场进行基于加权循环的试验。第5条适用于需要使用便携式排放测量系统（PEMS）在现场条件下的典型运行中评估发动机气体排放性能的情况。

This document specifies the measurement and evaluation methods for gaseous and particulate exhaust emissions from reciprocating internal combustion engines (RIC engines) in the field.This document is applicable when the emissions from RIC engines used in non-road machinery, industrial equipment, marine installations, generating sets, diesel rail traction or similar machinery applications need to be measured in the field. Clause 4 applies for the conduct of discrete-mode steady-state gaseous or particulate emission measurements at a single operating point or conduct a weighted cycle-based test in the field. Clause 5 applies where it is necessary to assess gaseous emissions performance of engines during typical in-service operation under field conditions using portable emission measurement systems (PEMS).
