5、rds bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organ
6、izations, governmental and non- governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are c

15、lding elements Part 6: Laboratory measurements of impact sound insulation of floors 1 Scope This part of ISO 140 specifies a laboratory method for measuring impact noise transmission through floors by using a standard tapping machine. The method is applicable to bare floors and also to floors with c
16、overings. The results obtained can be used to compare the impact sound insulation properties of floors and to classify floors according to their sound insulation capabilities. NOTE 1 Field measurements of impact sound insulation of floors are dealt with in ISO 140-7. NOTE 2 Laboratory measurements o
17、f the reduction of transmitted impact noise by floor coverings on a heavyweight standard floor are dealt with in ISO 140-8. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 140.
