Subclause 5.8.5 of IEC 62885-2:2016 applies with the second paragraph and Figure 9 removed; the third paragraph is replaced by the following paragraph, and Figure 101 is added:For each measuring point, the air flow and vacuum are recorded 15 s after the throttling. The cleaner is then again operated unthrottled for 15 s. This procedure is continued until all the entire curves have been plotted, the measuring point for maximum vacuum being the last one.
