Record broad-band vibration velocity (RMS). The horizontal measurement reads 7.1 mm/s .

Do not risk your career, your facility’s safety, or your legal standing with a pirated file. Visit the official ASME store, purchase the PDF (or access it via corporate subscription), and maintain a fully traceable, current standard in your engineering library. Record broad-band vibration velocity (RMS)
If your machinery specification was written before 1995, it likely calls out ASME B106.1m . For any new installation or retrofit, ISO 10816-3 is the preferred modern standard. However, you cannot mix the two. A vibration level of 4.5 mm/s might be "Zone B" under B106.1m but "Zone C" (alarm) under ISO 10816-3 for a specific pump. Practical Application: Using the Standard to Diagnose a Machine Let us look at a real-world scenario. A facility has a 150 kW centrifugal pump (flexible foundation) rotating at 1,800 RPM. An engineer obtains the legitimate ASME B106.1m PDF and performs a measurement: Flexible (simplistic) | Detailed classes based on machine
