Over deze norm
1.1 This classification provides a method for determining a rating that can be used to compare the levels of impact noise generated by a standard tapping machine and transmitted through different floor-ceiling assemblies.
1.2 The name given to the rating is assigned by the test method that invokes this classification.
1.3 This classification is applicable only to one third octave band impact noise data obtained using the standard tapping machine described in Test Methods E 492 and E 1007.
1.4 Test methods that invoke this classification include:
1.4.1 Test Method E 492 - the single-number rating is called impact insulation class (IIC).
1.4.2 Test Method E 1007 - the single-number rating is called field impact insulation class (FIIC).
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
