Overview

ISO 7113:1999 specifies requirements for single-piece metal cutting blades used on portable hand-held forestry machines - specifically brush cutters and brush saws. The third edition (1999) extends the scope to include circular saw blades and focuses on blade material quality, surface condition, marking, and basic dimensions and tolerances for saw-type blades. The standard replaces the second edition and transfers blade retention torque requirements to the relevant machine safety standard.

Key topics and technical requirements

  • Blade surface quality
    • Except for marking, blades must be free from surface imperfections deeper than 0.03 mm.
  • Blade material and bend test
    • Material must show no visible cracks after a specified bend test.
    • Test specimen: cut with length perpendicular to material grain; specimen width (35 ± 5) mm and length at least 10 mm longer than 2H.
    • Test conditions include an unlubricated specimen, V-block apparatus, ambient temperature 10 °C to 35 °C, and load application rate 1 mm/s to 10 mm/s.
  • Dimensions and tolerances (saw blades only)
    • Basic diameters, thicknesses, centre-hole sizes and run-out (total indicator reading) tolerances are specified (see standard table for exact values).
    • Verification of run-out uses a washer and measuring setup as illustrated in the standard.
  • Marking
    • Blades must be durably marked with at least:
      • Maximum allowed rotational speed (rpm)
      • Rotational direction (when applicable)
      • Manufacturer name or trademark
  • Standards committee and scope change
    • Prepared by ISO/TC 23/SC 17 (manually portable forest machinery). Retention torque requirement removed from this document and handled in the machine safety standard for brush cutters and grass trimmers.

Applications and who uses it

ISO 7113 is practical for:

  • Blade manufacturers - to design, produce and QC single-piece metal blades and saw blades for brush cutters.
  • Equipment OEMs and system integrators - to select compatible cutting attachments and ensure safe operating speeds and mounting.
  • Test laboratories and quality inspectors - to perform bend tests, surface inspections and run-out verification.
  • Procurement managers and safety officers - to specify compliant blades in purchasing documents and maintenance procedures.
  • Service technicians and end users - to understand marking and maximum permitted rpm information for safe operation.

Related standards

  • ISO 7112 - vocabulary for portable hand-held brush-cutters and grass-trimmers (referenced).
  • Machine safety standard(s) for brush cutters and grass trimmers - now address blade retention torque and related machine-level safety requirements.

Keywords: ISO 7113, portable hand-held forestry machines, brush cutters, single-piece metal blades, saw blade dimensions, bend test, blade marking, run-out tolerance.

Reference number
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.
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.
International Standard ISO 7113 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for
agriculture and forestry, Subcommitte SC 17, Manually portable forest machinery.
This third edition cancels and replaces the second edition (ISO 7113:1991), of which it constitutes a technical
revision. It extends the field of application to all single-piece metal blades for brush cutters, including circular saw
blades. The requirement for the blade retention torque has been deleted; it will be dealt with instead in the machine
safety standard for brush cutters and grass trimmers.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée aux
comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les projets de Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour
vote. Leur publication comme Normes internationales requiert l'approbation de 75 % au moins des comités
membres votants.
La Norme internationale ISO 7113:1999(F) a été élaborée par le comité technique ISO/TC 23, Tracteurs et
matériels agricoles et forestiers, sous-comité SC 17, Matériel forestier portatif à main.
Cette troisième édition annule et remplace la deuxième édition (ISO 7113:1991), dont elle constitue une révision
technique. Elle étend le domaine d'application à toutes les lames métalliques monobloc destinées aux débroussail-
leuses, y compris les lames de scies circulaires. Les exigences relatives au couple de retenue des lames ont été
supprimées. Ces points feront l'objet d'un traitement distinct dans la norme de sécurité des machines relative aux
débroussailleuses et aux coupe-herbe.
