本程序建立了稳态试验条件下柴油机进气流量测量的建议。所讨论的测量方法仅限于工业中常见的计量系统和相关设备，特别是喷嘴、层流装置和涡流脱落。该程序建立了准确性目标，并解释了设备的正确使用。关于柴油机排气质量流量测量的建议范围很小。

This procedure establishes recommendations on the measurement of diesel engine intake air flow under steady-state test conditions. The measurement methods discussed have been limited to metering systems and associated equipment found in common usage in the industry, specifically, nozzles, laminar flow devices, and vortex shedding. The procedure establishes accuracy goals as well as explains proper usage of equipment. The recommendations concerning diesel engine exhaust mass flow measurements are minimal in scope.
