Overview

IEC 60335-2-67:2002/AMD1:2005 is an important amendment to the international standard addressing the safety requirements specific to floor treatment and floor cleaning machines used in industrial and commercial settings. Developed by the International Electrotechnical Commission (IEC) Subcommittee 61J, this amendment refines and extends the base standard IEC 60335-2-67, ensuring enhanced safety protocols for electrically motor-operated cleaning appliances. It covers critical aspects like electromagnetic interference, mechanical and electrical safety, and user instructions, focusing on appliances such as water-suction cleaning machines and motorized cleaning heads.

Key Topics

• Scope Expansion and Definitions
  The amendment introduces new definitions, such as water-suction cleaning appliances and motorized cleaning heads, to better clarify appliance categories within industrial and commercial floor cleaning applications. It also highlights the loading of power outlets for accessories with resistive loads according to markings.

• Marking and Instructions
  Enhanced user guidance requirements include:

  • Clear marking with voltage, power input, manufacturer details, and applicable symbols (e.g., IEC 60417-5935 for motorized cleaning heads).
  • Mandatory cautionary notes in instruction manuals stressing safe use, including warnings against hazardous dust, wet outdoor use, and incompatible brush types.
  • Noise emission levels (A-weighted sound pressure level) and arm vibration acceleration values must be documented, emphasizing operator safety in noisy or vibration-prone environments.

• Mechanical and Electrical Safety Tests
  The amendment specifies rigorous testing protocols:

  • Resistance to moisture and saline solutions for motorized cleaning heads using standardized detergent solutions.
  • Mechanical strength tests for current-carrying hoses, including abrasion, flexing, crushing, torsion, and cold-temperature durability tests to ensure safe operation under industrial conditions.
  • Electrical withstand tests to confirm insulation integrity after mechanical and moisture exposure.
  • Abnormal operation scenarios such as locked brushes are tested to prevent hazards.

• Additional Safety Measures

  • Protection of rotating parts to prevent operator injury.
  • Requirements for supply cords, including regular inspection, correct replacement, and safe use precautions.
  • Compliance with safety symbols standards ISO 3864-1, ISO 7010, and IEC graphical symbols for consistency in safety communications.

Applications

IEC 60335-2-67 Amendment 1 principally applies to industrial and commercial floor cleaning and treatment machines, including:

• Floor scrubbers and polishers used in hotels, hospitals, schools, factories, malls, and office buildings.
• Water-suction cleaning appliances designed for wet and dry cleaning applications in commercial environments.
• Motorized cleaning heads fitted on flexible hoses for versatile cleaning tasks.
• Rental business equipment where safety and durability are paramount.

This standard ensures operators' safety by addressing electrical hazards, mechanical durability, noise and vibration exposure, and proper appliance marking. It aids manufacturers in designing robust appliances compliant with international safety regulations and helps businesses maintain safe cleaning operations.

Related Standards

IEC 60335-2-67 Amendment 1 references and complements various international standards critical for comprehensive appliance safety and testing:

• IEC 60704-1: Test codes for measuring airborne acoustical noise from household and similar electrical appliances.
• ISO 3864-1: Design principles for graphical safety symbols used in workplaces and public areas.
• ISO 5349: Measurement and evaluation of human exposure to hand-transmitted vibration, crucial for assessing the ergonomic impact of cleaning machines.
• ISO 6344-2: Grain size analysis for coated abrasives, relevant for testing hose abrasion resistance.
• ISO 7010: Standard graphical safety symbols for workplaces and public environments.
• IEC 60068 series: Environmental testing including impact, free fall, and water ingress protection tests to ensure mechanical and moisture resistance.
