GB 26509-2011 is a current mandatory Chinese national standard for Garden machinery - Pedestrian-controlled lawnmower with a petrol（diesel）engine - Safety requirements and testing methods. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Apr 1, 2012.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to pedestrian-controlled lawnmowers powered by petrol or diesel engines, commonly known as walk-behind mowers. It covers both rotary mowers and cylinder (reel) mowers used in garden and landscaping applications. The standard is mandatory for all manufacturers targeting the Chinese market. It also applies to corresponding parts of walk-behind mowers powered by other internal combustion engines and sulky-type units (excluding ride-on attachments). However, it does not apply to ride-on mowers or trimmers using non-metallic flexible lines with cutting energy not exceeding 10J.
Technical requirements
The standard specifies comprehensive safety requirements across mechanical, electrical, and operational aspects. It mandates protective guards for all power-driven components except cutting means and ground-contact parts, requiring specific opening sizes and safety distances. Manufacturers must design enclosures that prevent operator contact with blades and hot surfaces exceeding 80°C. For rotary mowers, the deck (台壳) must extend below the blade tip circle, and specific structural integrity is required for decks, covers, and grass catchers. The standard sets strict limits on blade stop time (e.g., ≤3s for cutting width ≤600mm) and requires braking systems for self-propelled mowers that meet specific distance and slope-holding criteria. It also addresses object projection prevention, requiring mowers to pass tests where steel balls are fired at target boards to ensure debris is contained. Electrical systems must include overload protection and proper insulation, while handle structures must withstand specific static forces. Regarding harmful emissions, the standard requires manufacturers to declare vibration and noise values in the manual if they exceed certain thresholds (e.g., vibration >2.5m/s²). It does not set absolute limit values for these but mandates measurement methods and user warnings. Compliance with labeling and manual requirements, including safety symbols per GB/T 4269 and GB 10396, is mandatory.
Testing methods
The standard mandates specific testing procedures to verify compliance. Key tests include the projectile containment test using steel balls and a specified test enclosure (Appendix B), the blade impact test where a steel pipe is inserted into the blade path (Section 4.17), and the unbalanced blade operation test (Section 4.18). It also specifies methods for measuring handle vibration (Appendix E) and noise emission (Appendix F) using engineering methods. Manufacturers must ensure their products pass these rigorous physical and environmental tests before market entry.
FAQs
What products are regulated under GB 26509-2011?
The standard regulates pedestrian-controlled lawnmowers powered by petrol or diesel engines, including both rotary and cylinder types. It also applies to corresponding parts of walk-behind mowers powered by other internal combustion engines and sulky-type units (excluding ride-on attachments).
Are there any updates from the previous version of GB 26509-2011?
GB 26509-2011 is the foundational version establishing mandatory safety requirements for these specific garden machines. It aligns with international practices by referencing standards like ISO 14121 and EN 836 for risk assessment and safety principles.
How does GB 26509-2011 differ from ISO standards?
While GB 26509-2011 incorporates principles from international standards like ISO 14121 and EN 836, it is a mandatory national standard specific to the Chinese market. It includes detailed, specific testing parameters and enclosure designs tailored to Chinese regulatory requirements for garden machinery.
