IEC 60335-2-67:2021

Overview

IEC 60335-2-67:2021 is the fifth-edition IEC safety standard that sets particular requirements for powered floor treatment machines for commercial use. It is a Part 2 standard of the IEC 60335 series and is to be used together with IEC 60335-1 (the general safety requirements). This edition (2021) replaces the 2012 edition and aligns editorially and technically with IEC 60335-1:2020.

The standard applies to commercial indoor and outdoor machines with a predominantly lateral or periodic cleaning motion used for scrubbing, wet or dry pick-up, polishing, buffing, waxing/sealing, shampooing, stripping, grinding and scarifying of artificial-surface floors. It covers mains-, battery- and internal-combustion-powered machines (including built-in battery chargers) within specified voltage limits.

Key topics and technical requirements

The standard supplements IEC 60335-1 with Part 2‑67 specific requirements covering, among others:

• Scope and classification of commercial floor treatment machines (traction-drive machines are excluded and covered by IEC 60335-2-72).
• Power systems: internal combustion engines; mains up to 250 V single-phase and 480 V for other systems; battery-operated machines (with possible built-in chargers).
• Electrical safety: leakage current, dielectric strength, transient overvoltages and charging requirements for built-in chargers and batteries.
• Mechanical and operational safety: stability, mechanical strength, protection against access to live parts, starting controls, overload protection and endurance/abnormal operation tests.
• Environmental resistance and durability: moisture resistance, resistance to heat, fire and rusting, and requirements for hoses and flexing tests.
• Marking, instructions and warnings required for safe use in commercial settings.
• Annexes addressing batteries, LPG engines, precast paving slab tests, and informative guidance on noise and vibration emissions.

Practical applications - who uses this standard

IEC 60335-2-67 is essential for:

• Manufacturers and designers of commercial floor care equipment (scrubbers, polishers, shampooers, grinders).
• Product safety and compliance engineers preparing technical files for certification and market approval.
• Test laboratories and certification bodies performing type and routine testing.
• Procurement and facilities managers specifying safe equipment for hotels, hospitals, schools, retail, factories and other commercial premises.
• Regulatory authorities adopting national safety rules based on IEC standards.
