Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
This part of ISO 140 specifies field methods for measuring the impact sound insulation properties of building floors by using a standard tapping machine. The metchod is applicable to bare floors and also to floors with coverings. The results obtained can be used to compare the impact sound insulation properties of floors and to compare the apparent impact sound insulation of floors and to compare the apparent impact sound insulation of floors with specified requirements. NOTE 1 - Laboratory measurements of impact sound insulation of floors are dealt with in ISO 140-6. NOTE 2 - Laboratory measurements of the reduction of transmitted impact noise by floor coverings on a heavyweight standard floor are dealt with in ISO 140-8.
