A complete compendium on how to make acceleration measurements
ARLINGTON HEIGHTS, IL (September 8, 2016) – IEST, the leading technical association for professionals in the field of environmental testing, releases IEST-RP-DTE011.2: Mechanical Shock and Vibration Accelerometer Selection. This Recommended Practice (RP) provides guidelines for selecting accelerometers to measure shock and vibration in laboratory and field testing environments.
IEST-WG-DTE011 Chair Jon Wilson explains, “IEST-RP-DTE011.2 is a unique, concise, and thorough document. This revision contains significant updates including the latest information on smart sensors.” Vice Chair Patrick Walter remarks, “This Recommended Practices is particularly valuable because it is effectively organized to serve as both a ready reference source and a comprehensive training aid. IEST-RP-DTE011.2 can provide the basis for training engineers, technicians, and quality assurance personnel to assure the most valid and accurate acceleration measurements.”
IEST-RP-DTE011.2: Mechanical Shock and Vibration Accelerometer Selection contains information on the most popular types of accelerometers, their principles of operation, performance characteristics, and comparisons of advantages and disadvantages. Additional sections discuss specific applications, with recommendations to assist in selecting the best accelerometer for those situations.
Updated by a working group comprised of a wide range of industry experts (manufacturers, users, consultants, and stakeholders), IEST-RP-DTE011.2 contains sections on accelerometer types for shock and vibration, dynamic characteristics, environmental characteristics, accelerometer installation, accelerometer recalibration, and accelerometer selection by application. IEST-RP-DTE011.2 is relevant to anyone selecting accelerometers for test and measurement applications in field, flight, fleet, or laboratory. This includes, but is not limited to, professionals performing automobile crash and ride testing; aerospace manufacturers measuring airframe, engine, and missile performance; agencies taking seismic measurements; sporting equipment manufacturers tuning equipment dynamics; hand tool manufacturers concerned with human ergonomics; the automobile racing community; the Department of Defense and Homeland security for weapons effects and prevention; and state of health equipment manufacturers.
This IEST Recommended Practice concentrates on mass-spring type accelerometers, with the sensing element(s) represented by the spring. Recommendations are made in terms of performance characteristics rather than instrument construction, brand, or model number. Various sensing technologies are discussed in detail to provide a good understanding of design trade-offs.
Print and electronic versions of IEST-RP-DTE011.2: Mechanical Shock and Vibration Accelerometer Selection are available through the bookstore at http://www.iest.org. Newly available from IEST for users of the 11.1 accelerometer selection document, redline copies allow a quick review of changes and additions from the 11.1 to the 11.2 version. Custom training on Mechanical Shock and Vibration Accelerometer Selection and Acceleration Measurement is available through the IEST Environmental Testing Learning Path Certificate program.
