Overview
The ISO 7112:2018 standard, titled "Machinery for forestry - Portable brush-cutters and grass-trimmers - Vocabulary," provides a comprehensive glossary of terms related to portable, hand-held brush-cutters and grass-trimmers. Developed by the International Organization for Standardization (ISO), this document defines essential terminology covering these forestry machines, their cutting attachments, power sources, and related safety and control components. The standard supports clear communication and consistency within the forestry machinery industry, contributing to safety, effective usage, and technical clarity.
ISO 7112:2018 is the fifth edition, reflecting minor revisions to its predecessor ISO 7112:2017. It is a key reference for manufacturers, operators, safety professionals, and regulatory bodies engaged in forestry machinery design, use, and maintenance.
Key Topics
ISO 7112:2018 systematically categorizes vocabulary into the following critical topics, ensuring detailed coverage of portable forestry machinery:
-
Work Functions: Defines operations such as felling (cutting down trees), shredding (breaking down bushes and small trees), and trimming (cutting grass and soft vegetation). It also includes terms like cutting means thrust-uncontrolled reactions during operation.
-
Machine Types: Classifies equipment such as brush-cutters (metal/plastic rotating cutters for tough vegetation), brush saws (brush-cutters with circular saw blades for cutting saplings), grass-trimmers (using flexible non-metallic lines), lawn-trimmers, and lawn edge-trimmers.
-
Cutting Equipment: Describes cutting devices including cutting means, saw blades, and flexible cutting means, each designed for specific vegetation types and purposes.
-
Safety Devices: Highlights vital safety components like cutting means retainers, cutting attachment guards, quick-release mechanisms, harnesses, throttle trigger lockouts, and hip pads. These features are crucial for operator safety and risk mitigation.
-
Control Systems: Defines engine and machine controls such as starter types (recoil and electric), choke, stop switch, primer, throttle controls and linkages, decompression valve, and throttle triggers-all essential for operational efficiency and safety.
-
Carburettor Settings: Details components for adjusting fuel and air mixtures, including idle speed adjusters and mixture screws vital for optimal engine performance.
-
Handles and Grips: Clarifies the types and roles of handles and handgrips, including components designed to improve machine handling and operator comfort.
-
Exhaust Systems: Covers exhaust-related devices like mufflers and spark arresters that manage noise and prevent fire hazards.
-
Miscellaneous Components: Includes power transmission shafts, clutches, governors, idling speeds, maximum power speeds, and dry weight definitions, providing a holistic understanding of machine construction.
-
Brush-cutter Position: Annex A provides a visual representation of the brush-cutter's suspension points and positioning to aid in understanding and operator training.
Applications
ISO 7112:2018 is a practical resource that benefits a range of forestry equipment stakeholders:
