Acoustics and vibration - Laboratory measurement of vibro-acoustic transfer properties of resilient elements - Part 1 : principles and guidelines

ISO 10846-1:2008 explains the principles underlying ISO 10846-2, ISO 10846-3, ISO 10846-4 and ISO 10846-5 for determining the transfer properties of resilient elements from laboratory measurements, and provides assistance in the selection of the appropriate part of this series. It is applicable to resilient elements that are used to reducethe transmission of audiofrequency vibrations (structure-borne sound, 20 Hz to 20 kHz) to a structure which may, for example, radiate fluid-borne sound (airborne, waterborne, or other), andthe transmission of low-frequency vibrations (typically 1 Hz to 80 Hz), which may, for example, act upon human subjects or cause damage to structures of any size when the vibration is too severe.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
