ANNEX I
METHOD OF MEASURING AIRBORNE NOISE EMITTED BY POWERED HAND-HELD CONCRETE-BREAKERS AND PICKS
SCOPE
THIS MEASUREMENT METHOD IS APPLICABLE TO POWERED HAND-HELD CONCRETE-BREAKERS AND PICKS , HEREINAFTER REFERRED TO AS " APPLIANCES " . IT SPECIFIES THE TEST PROCEDURES FOR USE IN DETERMINING THE SOUND POWER LEVEL OF SUCH EQUIPMENT FOR THE PURPOSE OF EEC TYPE-EXAMINATION AND TESTING AS TO CONFORMITY .
THESE TECHNICAL PROCEDURES SHALL COMPLY WITH THE REQUIREMENTS OF ANNEX I TO DIRECTIVE 79/113/EEC .
ALL THE SECTIONS IN ANNEX I TO DIRECTIVE 79/113/EEC SHALL APPLY TO APPLIANCES , SUBJECT TO THE FOLLOWING AMENDMENTS :
4 . CRITERIA TO BE USED FOR EXPRESSING RESULTS
4.1 . THE ACOUSTIC CRITERION FOR THE ENVIRONMENT OF AN APPLIANCE SHALL BE EXPRESSED BY ITS SOUND POWER LEVEL .
6 . MEASURING CONDITIONS
6.1.1 . DETERMINING THE MASS OF AN APPLIANCE .
WHEN THE MASS IS BEING DETERMINED , THE APPLIANCE SHALL BE FITTED OUT AS FOR NORMAL USE , EXCEPT FOR THE TOOL , THE SUPPLY TUBE AND , WHERE APPROPRIATE , THE COUPLING .
6.1.2 . SUPPORTS OF THE APPLIANCE .
( A ) TO ENSURE THAT THE TESTS ARE COMPLETELY REPRODUCIBLE , THE APPLIANCE SHALL BE COUPLED DURING THE TEST RUN TO A TOOL EMBEDDED IN A CUBE-SHAPED CONCRETE BLOCK PLACED IN A CONCRETED PIT SUNK INTO THE GROUND .
( B ) AN INTERMEDIATE STEEL PIECE MAY BE INSERTED DURING TESTS BETWEEN THE APPLIANCE AND THE SUPPORT TOOL . THIS INTERMEDIATE PIECE SHALL FORM A STABLE STRUCTURE BETWEEN THE APPLIANCE AND THE SUPPORT TOOL . THE DIAGRAM IN FIGURE 2 INCORPORATES THESE REQUIREMENTS .
6.1.3 . BLOCK CHARACTERISTICS .
THE BLOCK SHALL BE IN THE SHAPE OF A CUBE , 0,60 M MORE OR LESS 2 MM LONG AT THE EDGE AND AS REGULAR AS POSSIBLE ; IT SHALL BE MADE OF REINFORCED CONCRETE AND THOROUGHLY VIBRATED IN LAYERS OF UP TO 0,20 M TO AVOID EXCESSIVE SEDIMENTATION .
THE DISTANCE BETWEEN THE EXTREMITY OF THE APPLIANCE ( WITHOUT THE TOOL ) AND THE SCREENING SLAB SHALL BE BETWEEN 0,10 AND 0,20 M .
6.1.4 . COMPOSITION OF THE CONCRETE .
FOR ONE 50-KILOGRAM SACK OF PURE PORTLAND CEMENT , CATEGORY 400 OR EQUIVALENT :
- 65 LITRES OF UNGRADED , NON-CALCAREOUS SAND WITH A GRAIN SIZE OF 0,1 MM TO 5 MM ,
- 115 LITRES OF NON-CALCAREOUS ALLUVIAL GRAVEL WITH A GRAIN SIZE OF 5 TO 25 MM ,
THE CUBE SHALL BE REINFORCED BY 8-MM-DIAMETER STEEL RODS WITHOUT TIES , EACH ROD BEING INDEPENDENT OF THE OTHERS ; THE DESIGN CONCEPT IS ILLUSTRATED IN FIGURE
