American Petroleum Institute Standard 670 (API 670) was developed by users and manufacturers of machinery protection systems in the mid-1970s to address a significant industry need: a vendor-neutral specification that would define basic as well as optional functional requirements, performance criteria, interchangeability, standard part configurations, and generally-accepted good engineering practices for purchasing, installing, and using such systems. In short, API 670 would allow purchasers to say little more than “…must be API 670-compliant” and know exactly what they were getting.
API 670 has been extremely successful in accomplishing these objectives and is today the world’s most widely used standard for specifying vibration monitoring systems, both within the petroleum industries and in other industries such as power generation. Currently in its 5th Edition, its scope has grown over the years to encompass proximity and seismic transducers, as well as continuous monitoring of vibration, axial position, and bearing temperature. In addition to vibration monitoring, it covers overspeed, emergency shutdown, and surge detection systems, allowing special-purpose systems from a wider variety of suppliers to be addressed by the excellent guidelines in this standard.
Brüel & Kjær Vibro is pleased to be an active participant in the API 670 Task Force, a body of more than 75 individuals encompassing machinery OEMs, end users, engineering & procurement companies, and instrumentation manufacturers. Collectively, this globally diverse team works together to ensure the standard remains current, relevant, and accurate, and reflects the consensus of best practices among machinery protection system builders and users worldwide.
