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 1 .

6.1.5 . SUPPORTING TOOL .

THE TOOL SHALL BE SEALED INTO THE BLOCK AND SHALL CONSIST OF A RAMMER OF NO LESS THAN 178 MM OR NO MORE THAN 220 MM DIAMETER AND A TOOL CHUCK COMPONENT IDENTICAL TO THAT NORMALLY USED WITH THE APPLIANCES BEING TESTED AND COMPLYING WITH ISO RECOMMENDATIONS R 1180 AND R 1571 BUT SUFFICIENTLY LONG TO ENABLE THE PRACTICAL TEST TO BE CARRIED OUT .

SUITABLE TREATMENT SHALL BE CARRIED OUT TO INTEGRATE THE TWO COMPONENTS . THE TOOL SHALL BE FIXED IN THE BLOCK SO THAT THE BOTTOM OF THE RAMMER IS 0,30 M FROM THE UPPER FACE OF THE BLOCK ( SEE FIGURE 1 ) .

THE BLOCK SHALL REMAIN MECHANICALLY SOUND , PARTICULARLY AT THE POINT WHERE THE SUPPORTING TOOL AND THE CONCRETE MEET . BEFORE AND AFTER EACH TEST , IT SHALL BE ESTABLISHED THAT THE TOOL SEALED IN THE CONCRETE BLOCK IS INTEGRATED WITH IT .

6.1.6 . POSITIONING OF THE CUBE .

THE CUBE SHALL BE SET IN A PIT CEMENTED THROUGHOUT , COVERED BY A SCREENING SLAB OF AT LEAST 100 KG/M2 , AS INDICATED IN THE ATTACHED FIGURE 4 , SO THAT THE UPPER SURFACE OF THE SCREENING SLAB IS FLUSH WITH THE GROUND . TO AVOID ANY PARASITIC NOISE , THE BLOCK SHALL BE INSULATED AGAINST THE BOTTOM AND SIDES OF THE PIT BY ELASTIC BLOCKS , THE CUT-OFF FREQUENCY OF WHICH SHALL NOT BE MORE THAN HALF THE STRIKING RATE OF THE APPLIANCE TESTED , EXPRESSED AS STROKES PER SECOND .

THE OPENING IN THE SCREENING SLAB THROUGH WHICH THE TOOL CHUCK COMPONENT PASSES SHALL BE AS SMALL AS POSSIBLE AND SEALED BY A FLEXIBLE SOUND-PROOF JOINT .

6.2 . OPERATION OF THE SOUND SOURCE DURING MEASUREMENTS .

TO ENSURE THAT THE MEASUREMENTS MAY BE REPRODUCED , ALL APPLIANCES SHALL BE TESTED IN THE VERTICAL POSITION .

IN THE CASE OF PNEUMATIC APPLIANCES , THE AIR EXHAUST AXIS OF THE TEST APPLIANCE SHALL BE EQUIDISTANT FROM TWO MEASURING POINTS ( AIR EXHAUSTED DIRECTLY ON TO A MICROPHONE DISTORTS THE MEASUREMENT , WHICH CONSEQUENTLY HAS TO BE ABANDONED ) . THE MICROPHONE SHALL NOT BE PLACED BETWEEN THE APPLIANCE AND THE AIR RECEIVER ( SEE FIGURE 3 ) .

6.2.1 . NOT APPLICABLE .

6.2.2 . IN THE CASE OF PNEUMATIC APPLIANCES , THE OPERATION OF THE MACHINE SHALL HAVE THE SAME ACOUSTIC STABILITY AS IN NORMAL SERVICE AND SHALL SATISFY THE FOLLOWING REQUIREMENTS .

THE APPLIANCE SHALL OPERATE AT A WORKING PRESSURE OF 600 KPA .

IF THIS IS IMPOSSIBLE , THE PRESSURE USED AND THE REASONS WHY IT WAS IMPOSSIBLE TO USE THE STIPULATED PRESSURE SHALL BE INDICATED IN THE TEST REPORT .

DURING THE MEASUREMENTS , THE AIR PRESSURE SHALL BE MEASURED WHILE THE APPLIANCE IS IN OPERATION . THE APPLIANCE SHALL OPERATE NORMALLY ; ANY HINDRANCES TO THE AIR EXHAUST , SUCH AS ICING UP , SHALL BE AVOIDED . THE TYPE , QUALITY AND QUANTITY OF THE LUBRICATING OIL USED SHALL COMPLY WITH THE MANUFACTURER'S RECOMMENDATIONS .

IN THE CASE OF APPLIANCES POWERED OTHER THAN BY COMPRESSED AIR , THE OPERATING CONDITIONS SHALL BE THOSE CORRESPONDING TO THE MAXIMUM SPEED AT WHICH THE APPLIANCE CAN OPERATE CONTINUOUSLY , ACCORDING TO THE MANUFACTURER'S STATEMENT .

TEST SET-UP .

THE APPLIANCES SHALL RUN UNATTENDED BY AN OPERATOR IN THE MANNER DESCRIBED BELOW :

( A ) THE APPLIANCE SHALL OPERATE IN AN UPRIGHT POSITION ON THE DEVICE DESCRIBED IN 6.1.5 , WHICH SHALL BE PROVIDED WITH A TOOL SHANK OF THE CORRECT SIZE FOR ATTACHMENT TO THE APPLIANCE ;

( B ) THE APPLIANCE SHALL BE FIRMLY HELD DOWN BY A FLEXIBLE DEVICE IN ORDER TO GIVE THE SAME STABILITY AS THAT EXISTING UNDER NORMAL OPERATING CONDITIONS , WHEN THE TOOL IS EMBEDDED IN THE MATERIAL TO BE BROKEN UP BEFORE THE LATTER FRACTURES ; THE FLEXIBLE DEVICE MAY TAKE THE FORM OF CALIBRATED SPRINGS OR PNEUMATIC JACKS , FOR EXAMPLE .

PRESSURE CONTROL IN THE CASE OF APPLIANCES .

SINCE THE APPLIANCE HAS TO OPERATE AT 600 KPA OR AT ITS NOMINAL PRESSURE IF THIS IS DIFFERENT , THE PRESSURE SHALL BE CHECKED AT THE AIR INLET COUPLING TO THE APPLIANCE ( SEE FIGURE 3 ) .

THE PRESSURE MAY BE CHECKED BY MEANS OF A DIAL PRESSURE GAUGE BUT , IN VIEW OF THE PULSATION OF THE APPLIANCE , IT IS PREFERABLE TO USE AN ARRANGEMENT CONSISTING OF AN AIR RECEIVER OF 50 TO 100 LITRES CAPACITY SUPPLIED BY A 20-M-LONG 19-MM-DIAMETER TUBE . THE APPLIANCE SHALL BE SUPPLIED FROM THIS RECEIVER THROUGH A 25 - TO 30-MM-DIAMETER 4,5-M-LONG TUBE , CONNECTED TO THE COUPLING . THE AIR RECEIVER SHALL BE PLACED AS FAR AWAY AS POSSIBLE FROM THE APPLIANCE . THE PRESSURE INSIDE THE AIR RECEIVER SHALL BE MEASURED THROUGH A CONNECTION ON THE LATTER .

THE PRESSURE MAY BE ADJUSTED EITHER THROUGH THE OUTLET VALVE ON THE COMPRESSOR OR BY LEAKING PRESSURE FROM THE AIR RECEIVER THROUGH AN ADJUSTABLE SILENCER .

THIS DEVICE IS ILLUSTRATED SCHEMATICALLY IN FIGURE 3 .

6.3 . THE TEST AREA SHALL BE A MINIMUM OF 4 M IN RADIUS .

6.4.1 . MEASURING SURFACE .

THE MEASURING SURFACE TO BE USED FOR TESTING SHALL BE A HEMISPHERE . THE CENTRE OF THE HEMISPHERE SHALL BE THE VERTICAL PROJECTION ON TO THE REFLECTING PLANE OF THE GEOMETRIC CENTRE OF THE APPLIANCE . THE RADIUS IS GIVEN IN THE FOLLOWING TABLE :

MASS OF THE APPLIANCE AS NORMALLY USED * RADIUS OF THE HEMISPHERE * VALUE OF Z FOR POINTS 1 TO 8

LESS THAN 10 KG * 2 M * 0,75 M

10 KG OR MORE * 4 M * 1,50 M

6.4.2.2 . MEASURING POINTS .

FOR EACH APPLIANCE , THERE SHALL BE 12 MEASURING POINTS WITH THE VARIATIONS IN THE VALUE OF Z OF POINTS 1 TO 8 AS SHOWN IN THE PREVIOUS TABLE .

7 . MEASUREMENTS

7.1.1 . ONLY THE BACKGROUND NOISE SHALL BE TAKEN INTO ACCOUNT FOR THE PURPOSE OF CORRECTIONS .

8 . USE OF RESULTS

8.2 . NOT APPLICABLE .

8.6.2 . SINCE THE GROUND SURFACE OF THE TEST AREA IS MADE OF CONCRETE OR NON-POROUS ASPHALT , 8.6.2 IS NOT APPLICABLE AND C = 0 .

8.6.3 . THE ICING-UP WHICH IS CHARACTERISTIC OF THE OPERATION OF PNEUMATIC APPLIANCES SHALL BE AVOIDED DURING THE MEASUREMENTS .

9 . DATA TO BE RECORDED

A MODEL REPORT IS GIVEN IN THE APPENDIX .
