Place accelerometers on the bearing housing in three orthogonal axes (vertical, horizontal, axial).

For organizations building new reliability programs, is the recommended path. However, if you maintain equipment installed between 1985 and 2010, you will inevitably need the ASME B106.1m PDF for compliance and comparative trending. Conclusion: Act on the Standard, Not the Search Searching for "ASME B106.1m PDF" is the first step to solving a very real engineering problem: how to quantify and interpret machine vibration. The final step must be securing a legitimate, up-to-date copy. Place accelerometers on the bearing housing in three
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. However, if you maintain equipment installed between 1985
Record broad-band vibration velocity (RMS). The horizontal measurement reads 7.1 mm/s .
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:
This article serves as your definitive guide. We will explore what ASME B106.1m actually contains, why obtaining a legitimate PDF is legally and technically essential, how the standard applies to real-world machinery evaluation, and the common pitfalls engineers face when searching for this document online. First, it is vital to clarify the precise identity of this standard. ASME B106.1m-1985 (R2017) – "Mechanical Vibration and Shock of Rotating and Reciprocating Machinery – Measurement and Evaluation of Vibration Severity" – is the full title. Note the "m" suffix denotes that the values are presented in metric (SI) units, distinguishing it from older imperial versions.
