标准摘要
[中文适用范围]： SAE J968 的这一部分规定了流量测量系统，包括固定装置，用于对孔板型喷嘴和支架组件（在 SAE J968/1 中描述）中使用的单孔孔板进行流量测试，该组件旨在用于测试和在试验台上设置柴油喷射泵。流量测量系统和夹具可确保按照 SAE J968/1 的规定对直径为 0.4 至 0.8 毫米的整个孔口范围进行精确的流量测试。它主要供单孔孔板制造商使用。 [外文原描述]： This part of SAE J968 specifies the flow measuring system, including the fixture, to be used for flow testing the single hole orifice plates used in an orifice plate type nozzle and holder assembly (described in SAE J968/1) which is intended for testing and setting diesel fuel injection pumps on test benches.The flow measuring system and fixture ensure accurate flow testing of the entire range of orifices from 0.4 to 0.8 mm diameter as specified in SAE J968/1. It is intended primarily for use by the manufacturers of single hole orifice plates.Cross Reference: ISO 7440/2,J967_201512,J968/1_202103
