标准摘要
[中文适用范围]： 本文件规定了容积式真空泵的体积流量、基础压力、水蒸气耐受性、功耗和最低启动温度的测量方法，该真空泵在大气压力和通常的基础压力下排出气体 [外文原描述]： This document specifies methods for measuring the volume flow rate, base pressure, water vapour tolerance, power consumption, and the lowest start-up temperature of positive displacement vacuum pumps, which discharge gas against atmospheric pressure and with a usual base pressure <10 kPa. In this document, it is necessary to use the determinations of volume flow rate and base pressure specified in ISO 21360‑1. This document also applies to the testing of other types of pumps which can discharge gas against atmospheric pressure, e.g. drag pumps.
