Mechanical vibration of rotating and reciprocating machinery. Requirements for instruments for measuring vibration severity Ingestion-build-73935 A number of damp-proof course1 Scope This International Standard specifies requirements which it is necessary for a measuring instrument for vibration severity of machines to meet if inaccuracies of measurement made on the casing of machines, particularly when making repeated measurements for trend monitoring of a certain machine, are not to exceed a specific value. The instruments covered by this International Standard give direct indication or recording of root mean square (r.
