IEC 60335-2-124:2024 PDF

Overview

IEC 60335-2-124:2024 - "Household and similar electrical appliances – Safety – Part 2-124" is the new IEC safety standard that sets particular requirements for commercial dry ice blasting machines used for hand‑guided cleaning, decoating and stripping of surfaces, for indoor or outdoor commercial use. Edition 1.0 (2024) is an extended version that incorporates relevant content from IEC 60335-1:2020 (general requirements). The standard covers both mains‑powered machines (motors up to 250 V single‑phase and up to 480 V for other systems) and battery‑operated machines, and applies to machines that store dry ice or produce it internally. Traction‑drive machines are excluded.

Key topics and technical requirements

This standard builds on IEC 60335‑1 and includes sector‑specific requirements, test methods and safety measures, including:

• Scope and classification - intended use, exclusions (e.g., integrated compressed‑air generation, other transport gases than compressed air/nitrogen, robotic‑arm controlled nozzles, corrosive/explosive environments, vehicle/ship/aircraft use).
• Marking and instructions - essential labels, user and maintenance instructions tailored for dry ice blasting hazards.
• Electrical safety - protection against access to live parts, leakage current, electric strength at operating temperature, transient overvoltages and insulation requirements.
• Power and charging - power input/current measurement rules, battery charging safety and normative Annex B for battery‑operated appliances.
• Thermal and heating controls - limits on temperature rises, motor ageing tests, thermal motor protectors and overload protection.
• Mechanical integrity and ergonomics - stability, mechanical strength, protection against mechanical hazards during hand‑guided operation.
• Construction and wiring - internal wiring, components, supply connections, earthing and requirements for clearances and creepage distances.
• Environmental resistance and durability - moisture resistance, resistance to heat/fire, resistance to rusting, endurance and abnormal operation tests.
• Ancillary requirements and annexes - software evaluation (Annex R), needle‑flame test, capacitors, UV‑C effects, and guidance on test sequences.

Practical applications - who uses this standard

• Manufacturers of commercial dry ice blasting machines for design, product development and conformity assessment.
• Test laboratories and certification bodies conducting type and routine tests for CE/CB or national approvals.
• Product safety engineers and compliance managers preparing technical files, user manuals and risk assessments.
• Procurement and facility managers specifying safe equipment for industrial cleaning and surface‑preparation services.
• Safety consultants and regulators developing operational and maintenance rules for safe use.
