ÖNORM EN 996/A2

This noise test code is applicable to pile installation and extracting equipment as defined in 1.3b). This noise test code is applicable for impact hammers and extractors up to a maximum striking energy of 250 kNm and to vibrators, static pile pushing/pulling devices up to a power of 1000 kW of its power source. For equipment above these limits this noise test code may have to be adapted to accommodate the practical problems associated with the testing of large equipment. In such cases the details of adaptation shall be recorded and reported (see also G.5). This noise test code specifies all the information necessary to carry out the determination, declaration and verification of the noise emission characteristics of this equipment. It specifies noise measurement methods, installation, operating and mounting conditions that shall be used for the test. NOTE This noise test code is not intended for an exact comparison of noise levels generated by different types of equipment (i. e. impact hammers versus vibrators).
