vibration \u2014 Evaluation of machine vibration by measurements on rotating shafts \u2014 Part 1: General guidelines&#8221; \u2014 is the key international standard for measuring and judging vibration on the <em>rotating shaft<\/em> of a machine. It is the direct counterpart to <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/iso-10816-1\/\">ISO 10816<\/a> (now modernised as the <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/iso-20816-1\/\">ISO 20816<\/a> series), which deals with vibration measured on the non-rotating casing. Where the casing standard listens to the structure, ISO 7919 watches the shaft itself, using non-contact <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/proximity-probe\/\">n\u00e6rhetsprober<\/a> to measure the rotor&#8217;s movement relative to its bearings. That distinction matters most on large, critical machinery with fluid-film bearings \u2014 turbines, compressors, and large pumps \u2014 where the rotor&#8217;s true dynamic behaviour is the difference between safe running and a wrecked bearing.<\/p>\n<h2>1. Anvendelsesomr\u00e5de og m\u00e5leprinsipp<\/h2>\n<p>The standard sets out general procedures for measuring and evaluating vibration on rotating shafts. Its founding principle is that the quantity of interest is the vibratory motion of the shaft itself, normally measured <em>relativ<\/em> to the stationary bearing housing. This is the critical departure from casing measurements covered by ISO 20816. Shaft vibration is the preferred measurement on machines whose rotor is massive compared with a relatively flexible casing and which run in fluid-film <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/journal-bearing\/\">journallager<\/a>. In those cases, large shaft motion can occur inside the bearing clearance without ever being transmitted to the outside of the housing \u2014 so a casing accelerometer would simply miss it. The goal is to assess the severity of this dynamic shaft motion and so protect the machine from bearing damage or <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/rotor-rub\/\">rotor-stator-kontakt<\/a>.<\/p>\n<h2>2. Measurement Quantities<\/h2>\n<p>The standard specifies which parameters to measure and evaluate. The primary quantity for overall <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/vibration-severity\/\">vibrasjonsintensitet<\/a> er <strong>S<sub>pp<\/sub><\/strong>, den <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/peak-to-peak\/\">topp-til-topp<\/a> vibratory <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/displacement\/\">forskyvning<\/a> of the shaft. This represents the total excursion of the shaft centreline as it moves within the bearing, and because it is expressed in micrometres it can be compared directly against the physical bearing clearance \u2014 a uniquely useful property for machinery protection.<\/p>\n<p>The standard also values other quantities for diagnostics. It recommends that the measurement system be able to provide:<\/p>\n<ul>\n<li><strong>Den <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/orbit\/\">akselbane<\/a><\/strong> \u2014 the path traced by the shaft centreline, essential for diagnosing problems such as <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/oil-whirl\/\">oljevirvel<\/a> eller <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/misalignment\/\">feiljustering<\/a>.<\/li>\n<li><strong>The average <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/shaft-centerline\/\">shaft centreline position<\/a><\/strong> \u2014 a shift in which can flag a change in load or alignment.<\/li>\n<li><strong>Filtered values<\/strong> \u2014 for some applications the vibration at 1\u00d7 <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/running-speed\/\">l\u00f8pehastighet<\/a> is evaluated separately to isolate the <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/unbalance\/\">ubalanse<\/a> response.<\/li>\n<\/ul>\n<h2>3. Instrumentation and Mounting<\/h2>\n<p>This part gives practical guidance on the hardware. It specifies a non-contacting probe system built from three components that are calibrated together and are <em>ikke<\/em> interchangeable:<\/p>\n<ul>\n<li><strong>The probe (sensor)<\/strong> \u2014 the <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/eddy-current-probe\/\">virvelstr\u00f8m<\/a> sensing tip.<\/li>\n<li><strong>An extension cable<\/strong> of a defined length.<\/li>\n<li><strong>A driver (proximitor)<\/strong> that conditions the signal.<\/li>\n<\/ul>\n<p>Probes are mounted in pairs at each bearing, set 90\u00b0 apart in an X\u2013Y configuration. This lets the system capture the full two-dimensional motion of the shaft centreline and reconstruct the orbit. The standard stresses that installation quality is critical: rigid mounting brackets, correct probe gapping, and a smooth &#8220;probe track&#8221; on the shaft that is free of mechanical or electrical <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/run-out\/\">utl\u00f8p<\/a> which would otherwise corrupt the signal. Because mechanical and electrical runout add a once-per-revolution error that masquerades as vibration, slow-roll compensation at low speed is normally applied before the data is trusted.<\/p>\n<h2>4. Evaluation Criteria and Zones<\/h2>\n<p>The standard offers two complementary ways to judge severity. The first is an <strong>absolute criterion<\/strong>: the measured S<sub>pp<\/sub> is compared against predefined limits using a four-zone model.<\/p>\n<ul>\n<li><strong>Sone A (Bra):<\/strong> the vibration level expected of newly commissioned machinery.<\/li>\n<li><strong>Sone B (Tilfredsstillende):<\/strong> egnet for ubegrenset langvarig drift.<\/li>\n<li><strong>Sone C (utilfredsstillende):<\/strong> a potential problem; the machine should be investigated to find the cause.<\/li>\n<li><strong>Sone D (uakseptabelt):<\/strong> levels considered damaging, requiring immediate action.<\/li>\n<\/ul>\n<p>The second is a <strong>change criterion<\/strong>: a significant increase in vibration from a known <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/baseline\/\">grunnlinje<\/a> can be an early warning of a developing fault even when the absolute level is still inside the &#8220;Satisfactory&#8221; zone. Part 1 supplies only this general framework \u2014 the specific numerical zone boundaries live in the machine-specific parts of the ISO 7919 series, because the allowable displacement of a large slow turbine differs greatly from that of a small high-speed compressor. As a rule, the boundaries are scaled against the maximum shaft speed and, ultimately, against the available bearing clearance.<\/p>\n<h2>5. Setting Alarms: Alert and Trip<\/h2>\n<p>The final section turns the evaluation criteria into a working <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/machinery-protection\/\">maskinbeskyttelse<\/a> system, recommending a two-tier alarm strategy:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/vibromera.eu\/nb\/glossary\/alarm-level\/\">Varsle<\/a> (alarm) setpoint:<\/strong> placed just above the machine&#8217;s normal, stable operating baseline. Breaching it warns the operator that conditions have changed and that an investigation is warranted.<\/li>\n<li><strong><a href=\"https:\/\/vibromera.eu\/nb\/glossary\/trip-level\/\">Tur<\/a> (shutdown) setpoint:<\/strong> an absolute limit set where continued running would likely cause severe damage. Breaching it should trigger an automatic shutdown to prevent catastrophic failure.<\/li>\n<\/ul>\n<p>The standard advises basing these setpoints on <em>b\u00e5de<\/em> the absolute zone boundaries \u2014 a Trip should not be set above the Zone C\/D boundary \u2014 and on significant change from baseline; an Alert might be triggered if vibration doubles, even while it remains in Zone B. This pairing of absolute and relative logic is exactly what a continuous protection system needs to catch both gross excursions and slow drift.<\/p>\n<h2>6. Key Concepts in Practice<\/h2>\n<ul>\n<li><strong>Shaft vs. casing vibration:<\/strong> for machines with massive, stiff rotors and flexible casings, the motion of the shaft is a far more direct and reliable indicator of dynamic state than whatever reaches the outside of the housing.<\/li>\n<li><strong>Machinery protection first:<\/strong> although the data also feeds diagnostics, the primary role of the ISO 7919 framework is real-time protection against catastrophic failure.<\/li>\n<li><strong>The value of relative motion:<\/strong> measuring the shaft against the bearing lets an analyst gauge directly how much of the bearing clearance is being used, and pin down issues such as oil whirl or excessive <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/preload\/\">forspenning<\/a>.<\/li>\n<\/ul>\n<p>Where this standard governs permanently instrumented critical machines, portable instruments cover the complementary job of field diagnosis and on-site correction. A two-channel analyser such as the <a href=\"https:\/\/vibromera.eu\/nb\/produkt\/balanset-1\/\">Balanset-1A<\/a> measures the 1\u00d7 amplitude and <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/phase\/\">fase<\/a> in the machine&#8217;s own bearings at operating speed, so an engineer can confirm that an unbalance flagged by a shaft-vibration trend really is unbalance \u2014 and then balance the rotor and verify the result without disturbing the installed proximity-probe system.<\/p>\n<h2>7. The Standard and Its Family<\/h2>\n<p>ISO 7919-1 is the umbrella &#8220;general guidelines&#8221; document; the numbered parts that follow it (covering specific machine classes such as steam turbines, gas turbines, and coupled industrial machines) supply the actual numerical limits. Read alongside the casing-based ISO 20816 series, it completes the two-sided picture of machine vibration \u2014 shaft motion on one side, structural response on the other \u2014 that any rigorous monitoring programme on <a href=\"https:\/\/vibromera.eu\/nb\/glossary\/critical-machinery\/\">kritisk maskineri<\/a> relies upon. The full, legally authoritative text is published by the International Organization for Standardization and must be purchased from the official ISO catalogue; this article summarises its structure and intent so the concepts can be applied without the document in hand.<\/p>\n<hr>\n<p><a href=\"https:\/\/vibromera.eu\/nb\/glossary\/\">\u2190 Tilbake til hovedindeksen<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>En oversikt over ISO 7919-1, den generelle retningslinjen for m\u00e5ling og evaluering av vibrasjon p\u00e5 roterende aksler, vanligvis ved bruk av ber\u00f8ringsfrie n\u00e6rhetsprober.<\/p>","protected":false},"featured_media":0,"template":"","meta":{"ai_generated_summary":"","footnotes":""},"categories":[109,112],"tags":[],"class_list":["post-20611","glossary","type-glossary","status-publish","hentry","category-glossary","category-iso-standards"],"_links":{"self":[{"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/glossary\/20611","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/glossary"}],"about":[{"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/types\/glossary"}],"version-history":[{"count":1,"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/glossary\/20611\/revisions"}],"predecessor-version":[{"id":101451,"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/glossary\/20611\/revisions\/101451"}],"wp:attachment":[{"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/media?parent=20611"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/categories?post=20611"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vibromera.eu\/nb\/wp-json\/wp\/v2\/tags?post=20611"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
