Description / Abstract:
This part of ISO 16251 specifies a laboratory measurement method
to determine the improvement of impact sound insulation by a floor
covering when laid on a standard concrete floor mock-up and excited
by a standard tapping machine. The method is restricted to soft,
flexible floor coverings, which transmit impact sound mainly
"locally" into the floor, i.e. through the area close to the points
of excitation, so that the size of the flooring specimen does not
have an influence on the results. Examples of such floor coverings
are carpets, PVC, and linoleum. These floor coverings correspond to
ISO 10140-1:2010[5], Annex H, category I.
The results only provide information about the noise radiated. A
subjective classification of the quality of the floor coverings is
not intended.
The method is kept as close as possible to the ISO 10140[4]
series and yields the same results within the range of uncertainty
and within the range of application. In the case of difference with
ISO 10140, the result of the ISO 10140 measurement shall be
used.
This part of ISO 16251 provides the measurement method. Product
test codes can contain further requirements concerning the
specimens, such as temperature range, the number of test specimens
or special mounting conditions.
NOTE If non-soft, non-flexible floorings are tested, e.g. those
with a laminated structure, increased deviations from the results
of the ISO 10140[4] series method may occur due to the dependency
on the specimen size.
