IEC 60335-2-72:2016 Overview

IEC 60335-2-72:2016 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies safety requirements for floor treatment machines designed for commercial use. This includes powered ride-on and walk-behind machines, equipped with or without traction drive systems, intended for indoor and outdoor applications such as sweeping, scrubbing, polishing, waxing, sealing, and shampooing floors with artificial surfaces.

The standard is essential for ensuring the safe design, construction, and operation of these machines across various commercial environments, including hotels, schools, hospitals, factories, retail outlets, and office buildings. It applies to machines powered by internal combustion engines, mains electricity, or batteries-covering a wide range of power input types and voltages.

IEC 60335-2-72:2016 represents the fourth edition of this standard, bringing major technical revisions that reflect the latest state of the art and regulatory best practices in safety engineering for commercial cleaning machines. It must be used alongside IEC 60335-1:2010, which provides general safety requirements for household and similar electrical appliances.

Key Topics Covered

• Scope and Applications: Covers powered floor treatment machines for commercial settings, detailing applications like sweeping, scrubbing, and polishing.
• Power Systems: Addresses machines powered by internal combustion engines, mains voltage (up to 250 V single-phase or 480 V multi-phase), and battery-powered systems, including built-in chargers.
• Safety Requirements: Includes clauses on protection against electric shock, prevention of mechanical hazards, overload protection, moisture resistance, and electrical insulation.
• Marking and Instructions: Sets requirements for clear, correct labeling and user instructions to ensure safe operation and maintenance.
• Noise and Vibration Emission: Introduces new informative annexes (Annex DD and EE) that provide guidance on measuring acoustical noise and vibration emissions-a key factor in operator safety and comfort.
• Mechanical and Electrical Testing: Defines test procedures related to mechanical strength, stability, leakage current, electric strength, and endurance to ensure reliability under commercial use conditions.
• Special Features: Includes additional requirements for traction drive systems and performance under abnormal conditions.

Practical Applications

IEC 60335-2-72:2016 is crucial for manufacturers, testing laboratories, certification bodies, and commercial users aiming to:

• Design Compliant Machines: Use the standard’s specific safety criteria to engineer floor treatment machines suitable for commercial use, ensuring legal and safety compliance worldwide.
• Certify Safety and Performance: Facilitate the testing and certification process by adhering to established test methods, such as leakage current measurement and mechanical hazard assessments.
• Improve User Safety: Inform the development of clear user instructions and safety labels, minimizing risks related to electrical hazards, mechanical injury, or exposure to noise and vibration.
• Maintain Equipment Reliability: Support durability through defined endurance and moisture resistance tests, helping machines perform reliably in demanding commercial environments.
• Reduce Environmental Impact: Control noise and vibration emissions, improving workplace conditions and contributing to occupational health.
