IEC 60335-2-111:2024

Overview

IEC 60335-2-111:2024 - "Household and similar electrical appliances - Safety - Part 2-111" is the second edition safety standard for electric ondol mattresses with a non‑flexible heated part. It applies to appliances rated at not more than 250 V (including DC), and includes battery‑operated versions and the control units supplied with the appliance. This 2024 edition cancels and replaces the 2015 edition and is aligned with IEC 60335-1:2020. Notable technical updates include conversion of some notes to normative text and the introduction of test probe 19.

Key topics and technical requirements

The standard sets particular safety requirements that supplement the general requirements of IEC 60335-1. Main technical topics covered include:

• Scope and exclusions - household and similar use, community/spa use and cold‑climate applications are included; excludes industrial appliances, corrosive/explosive atmospheres and a range of other heating appliance types (see related standards).
• Protection against access to live parts and electrical insulation requirements.
• Heating performance and temperature limits - specific tests and temperature‑rise requirements for the non‑flexible heated part.
• Leakage current and electric strength at operating temperature - including test arrangements and measurement procedures.
• Moisture resistance and abnormal operation tests to simulate real‑life fault conditions.
• Stability, mechanical hazards and mechanical strength - requirements for safe construction and use.
• Construction, internal wiring and components - requirements for cords, terminals, earthing and clearances/creepage distances.
• Battery‑operated appliances and detachable/separable batteries (normative Annex B).
• Endurance, overload protection, and thermal protection for transformers and heating elements.
• Marking, instructions and user safety information - labeling and instructions that accompany the appliance.
• Normative and informative annexes covering tests such as needle‑flame, motor ageing, software evaluation, UV‑C effects, and more.

Practical applications - who uses this standard

IEC 60335-2-111 is essential for:

• Manufacturers and product designers creating electric ondol mattresses or integrated control units - for safe design and compliance.
• Test laboratories and certification bodies conducting safety testing and conformity assessment to IEC 60335 series requirements.
• Compliance and regulatory teams ensuring products meet national and international safety regulations.
• Procurement and quality assurance for specifying compliant products used in households, community spas or cold‑climate installations.

Using this standard together with the latest IEC 60335-1 edition ensures harmonized, up‑to‑date electrical safety testing and documentation for ondol mattress products.
