What is BS EN 60068-2-65 - Vibration test by acoustically induced method about?
BS EN 60068-2-65 is a European Standard and a part of the BS EN 60068 series that discusses vibration using the acoustically induced method for environmental testing. Environmental testing is the measurement of the performance of equipment under specified environmental conditions, such as extremely high and low temperatures.
BS EN 60068-2-65 provides standard procedures and guidance for conducting acoustic tests to determine the ability of a specimen to withstand vibration caused by a specified sound-pressure level environment to which it is, or is liable to be, subjected. BS EN 60068-2-65 determines the mechanical weakness and/or degradation in the performance of specimens and uses this information, in conjunction with the relevant specification, to decide on their acceptability for use. The methods of the test may also be used as a means of establishing the mechanical robustness or fatigue resistance of specimens.
Two procedures are described for conducting tests and for measurement of the sound pressure levels within the acoustic noise field and considering the need for measurement of the vibration responses at specified points on the specimen. It also gives guidance for the selection of the acoustic noise environment, spectrum, sound pressure level and duration of exposure.
Who is BS EN 60068-2-65 - Vibration test by acoustically induced method for?
BS EN 60068-2-65 on vibration test by acoustically induced method applies to:
- Electrical engineers
- Manufacturers of electrical and electronic equipment and components
- Laboratory testing personnel
- Quality testing personnel
- Manufacturers of laboratory equipment
Why should you use BS EN 60068-2-6 - Vibration test by acoustically induced method?
Environmental testing is the measurement of the performance of equipment under specified environmental conditions, such as extremely high and low temperatures, large, swift variations in temperature, blown and settling sand and dust, salt spray and salt fog. Acoustic Induced Vibration (AIV) refers to the high acoustic energy generated by pressure-reducing devices that excite pipe shell vibration modes, producing excessive dynamic stress.
BS EN 60068-2-65 provides acoustic environments and requirements for testing in which it determines the ability of a specimen to operate or survive in a specified high-intensity acoustic noise field. In practice, the fluctuating pressure environment exerted on a specimen under consideration may be a complex combination of progressive waves and reverberant acoustic fields.
BS EN 60068-2-65 covers the acoustic testing which applies to components, equipment, functional units and other products, hereinafter referred to as “specimens”, which are liable to be exposed to and/or are required to function in conditions of high sound pressure levels. BS EN 60068-2-65 provides comprehensive guidance useful throughout the process of production.
What’s changed since the last update?
BS EN 60068-2-65:2013 supersedes EN 60068-2-65:1994 which is withdrawn. It includes:
- Minor technical and editorial changes were made throughout the document as originally requested by the DE National Committee
- Following comments at the CD stage, particularly from the UK National Committee, significant technical and editorial additions were made to the standard for acoustic testing employing the progressive wave tube technique.
