Mechanical vibration - Hand-held and hand-guided machinery - Principles for evaluation of vibration emission (ISO 20643:2005)
ISO 20643:2005 provides the basis for the drafting of vibration test codes for hand-held and hand-guided power-driven machinery. It specifies the determination of hand-transmitted vibration emission in terms of frequency-weighted root-mean-square (r.m.s.) acceleration during type testing. For machines where vibration test codes do not exist, it can also be used for determination of emission values and contains sufficient guidance for designing an appropriate test. It is applicable to hand-held power tools (e.g. chipping hammers, sanders), hand-guided powered machines (e.g. lawn mowers, single-axle tractors, vibratory rollers), and other types of powered machines fitted with handles, guiding beams or similar means of control, of all power sources (electrical, hydraulic, pneumatic, internal combustion engine, etc.). It is not applicable to fixed machinery in which the vibration is transmitted to the hands of the user through the workpiece, nor to vibration transmitted from steering wheels or control levers of mobile machinery where the operator's position is on the machine.
Mechanische Schwingungen - Handgehaltene und handgeführte Maschinen - Grundsätzliches Vorgehen bei der Ermittlung der Schwingungsemission (ISO 20643:2005)
Dieses Dokument stellt die Grundlage für die Erstellung von Schwingungsmessnormen für handgehaltene und
handgeführte kraftbetriebene Maschinen dar. Es legt die Ermittlung der Hand-Arm-Schwingungen, angegeben
als Effektivwert der frequenzbewerteten Beschleunigung, während der Typprüfung (Messung von Maschinenkennwerten)
fest. Es kann auch zur Ermittlung der Schwingungsemissionswerte (Schwingungskennwerte)
solcher Maschinen herangezogen werden, für die keine Schwingungsmessnormen vorliegen, und stellt eine
hinreichende Anleitung zur Gestaltung einer geeigneten Prüfung dar.
ANMERKUNG Schwingungsmessnormen, die auf diesem Dokument beruhen, sollten Verfahren zur Ermittlung von
Maschinenkennwerten festlegen, welche wiederholbare und vergleichbare Ergebnisse unter kontrollierten Bedingungen
liefern, die so weit wie möglich in Übereinstimmung mit den Schwingungswerten an den Kontaktflächen zwischen Hand
und Maschine sind, die unter realen Arbeitsbedingungen gemessen werden, und deren Messunsicherheit quantifiziert wird.
Dieses Dokument gilt für handgehaltene Maschinen (z. B. Meißelhammer, Schwingschleifer), handgeführte
Maschinen (z. B. Rasenmäher, Einachs-Traktor, Rüttelwalze) und andere Maschinenarten, die mit Griffen,
Holmen oder ähnlichen Lenkvorrichtungen versehen sind. Es gilt für motorbetriebene Maschinen, die sich aus
beliebiger Fremdenergie speisen (elektrisch, hydraulisch, pneumatisch, Verbrennungsmotor usw.).
Es gilt nicht für stationäre Maschinen, bei denen die Schwingungen über das Werkstück auf die Hände der
Bedienungsperson (des Beschäftigten) übertragen werden.
Dieses Dokument ist nicht auf die Schwingungen anwendbar, die von Lenkrädern oder Steuerhebeln
(Stellteilen) beweglicher Maschinen ausgehen, bei denen sich der Arbeitsplatz der Bedienungsperson auf der
Maschine befindet (siehe EN 1032).
Vibration mécanique - Machines tenues et guidées à la main - Principes pour l'évaluation d'émission de vibration (ISO 20643:2005)
L'ISO 20643:2005 fournit la base pour l'élaboration des codes d'essai de vibrations pour les machines à moteur tenues à la main et guidées à la main. Elle spécifie la détermination de l'émission vibratoire en terme de moyenne quadratique (r.m.s) d'accélération pondérée en fréquence pendant l'essai de type. Pour les machines où le code d'essai de vibrations n'existe pas, elle peut être utilisée également pour la détermination de valeurs d'émission et comporte suffisamment d'informations pour la mise en place d'un essai. Elle est applicable aux machines à moteur portatives (par exemple marteaux burineurs, ponceuses), aux machines guidées à la main (par exemple tondeuses à gazon, tracteurs à essieu unique, compacteurs vibrants) et aux autres types de machines à moteur munies de poignées, de manches de guidage ou d'autres moyens de commande similaires. Elle est applicable aux machines fonctionnant avec tout type de puissance non manuelle (électrique, hydraulique, pneumatique, moteur à combustion interne, etc. ). Elle ne s'applique pas aux machines fixes pour lesquelles les vibrations sont transmises aux mains de l'opérateur via la pièce ainsi qu'aux vibrations transmises par les volants de direction ou les leviers de commande des machines mobiles quand la position de l'opérateur est sur la machine.
Mehanske vibracije - Prenosni ročni in ročno vodeni stroji - Načela vrednotenja oddajanja vibracij (ISO 20643:2005)
Ta dokument podaja osnovo za pripravo osnutkov preskusnih številk vibracij za prenosne ročne in ročno vodene stroje s pogonsko enoto. Določa ugotavljanje oddajanja vibracij, ki se prenašajo na roke, glede na efektivno vrednost (r.m.s.) frekvenčno uravnoteženega pospeška med preskušanjem. Pri strojih, ki nimajo preskusnih številk vibracij, se lahko uporabi tudi za ugotavljanje količine oddajanja, pri čemer vsebuje tudi zadostna navodila za načrtovanje primernega preskusa. OPOMBA Preskusne številke vibracij, ki temeljijo na tem dokumentu, naj bi opredelile merilne postopke, ki zagotavljajo nadzorovane in ponovljive rezultate, ki so v največji meri skladne s količino vibracij, ki se izmeri na površinah, kjer se stikata roka in stroj, ter so pridobljene pod resničnimi delovnimi pogoji, pri čemer so za njih opredeljene spremenljivosti merjenja. Ta dokument se uporablja za prenosna ročna orodja (npr. razbijalna kladiva, brusilniki), ročno vodene stroje (npr. kosilnice, enoosni traktorji, vibracijske valjarje) in druge vrste strojev s pogonsko enoto, ki imajo nameščene ročaje, vodilne žarke ali podobne načine upravljanja. Uporablja se za stroje, ki uporabljajo vse vire energije (električne, hidravlične, pnevmatične, motorje z notranjim izgorevanjem idr.). Ne uporablja se za pritrjene stroje, pri katerih se vibracije na roke uporabnika prenašajo prek obdelovanca. Ta dokument se ne uporablja za vibracije, ki se prenašajo prek volanov ali kontrolnih vzvodov mobilnih naprav na mestu za upravljavca stroja, (glej standard EN 1032). Omejen je na prevodne vibracije, ki se izmerijo v treh pravokotnih smereh na vmesniku ročnega stroja. Pri uporabi tega dokumenta je potrebna posebna pazljivost pri strojih, ki proizvajajo enotne in ponovljive sunke s pogostostjo ponavljanja, ki je nižja od 5 Hz. Pri takih strojih ni znano, ali so efektivne vrednosti frekvenčno uravnoteženega pospeška povezane z zdravstvenimi tveganji, zato so potrebne dodatne meritve. Pri razvijanju testnih številk vibracij za te stroje je treba upoštevati informacije v standardu CEN ISO/TS 15694. Ta dokument se ne uporablja za testne številke vibracij, ki so bile objavljene, preden je odbor CEN izdal ta dokument, ter za prenosne ročne in ročno vodene stroje, ki so bili izdelani pred tem datumom in kadar se uporabljajo kot preskusne številke. Ta dokument ne predpisuje omejitev ali priporočenih vrednosti vibracij. Ne podaja navodil ali priporočil za ugotavljanje človekove izpostavljenosti vibracijam na delovnem mestu.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards 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 organizations, 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 20643 was prepared by the European Committee for Standardization (CEN) in collaboration with
Technical Committee ISO/TC 118, Compressors, pneumatic tools and pneumatic machines, Subcommittee
SC 3, Pneumatic tools and machines, in accordance with the Agreement on technical cooperation between
ISO and CEN (Vienna Agreement).
Throughout the text of this document, read “.this European Standard.” to mean “.this International
Standard.”.
For the purposes of this International Standard, the CEN annex regarding fulfilment of European Council
Directives has been removed.
