Overview

EN 60335-2-17:2013/A1:2020 (CENELEC/IEC) is the European amendment to the safety standard for household and similar electrical appliances - Part 2‑17: particular requirements for blankets, pads, clothing and similar flexible heating appliances. It incorporates IEC 60335‑2‑17:2012/A1:2015 with CENELEC modifications and adds requirements for electro‑conductive textiles, marking, tests and conformity with the Low Voltage Directive (2014/35/EU) (see Annex ZZ). Key implementation dates in the foreword include a latest national adoption date (dop) of 2020‑10‑24 and withdrawal of conflicting standards (dow) by 2023‑04‑24.

Key topics and technical requirements

• Scope & classification: Applies to flexible heating appliances such as electric blankets, underblankets, heating pads, heated clothing and mattresses that incorporate heating elements or electro‑conductive textiles.
• New/clarified definitions: Adds and updates definitions (e.g., electro‑conductive textile, heating conductor, mattress for supporting the human body).
• Marking & instructions: Updates to mandatory symbols (ISO 7000 registered symbols) and requirements for user instructions, including warnings and symbol explanations.
• Heating & temperature tests: Surface temperature measurement methods (thermocouples fixed with thin adhesive tape), applicability of insulation criteria to electro‑conductive textiles, and specific test conditions for normal and abnormal operation.
• Abnormal operation tests: Detailed procedures for folding/bunching and loading to simulate hazardous conditions:
  • Blankets: five‑thickness fold with 300 mm × 450 mm × 72 mm thermal insulation sheet and 5 kg mass.
  • Pads: three‑thickness fold with the same insulation sheet and 5 kg mass.
  • Mattresses: bunching five runs over 150 mm, insulation sheet and 5 kg mass; alternate procedures if bunching is not possible.
• Electrical & mechanical tests: Updates on leakage current, electric strength, moisture resistance and mechanical strength for flexible parts incorporating electrodes or electro‑conductive textiles.
• Normative references: Replaces ISO 3758 with ISO 7000:2014 for graphical symbols.

Practical applications & users

Who uses this standard:

• Manufacturers and product designers of electric blankets, heated mattresses, heated clothing and pads - to design safe products and prepare compliance documentation.
• Test laboratories and conformity assessment bodies - to perform standardized temperature, electrical, mechanical and abnormal‑condition tests.
• Regulatory and certification authorities - to evaluate CE marking evidence under the Low Voltage Directive.
• Compliance engineers and technical writers - to prepare user instructions, labels and safety information aligned with ISO 7000 symbols.

Why it matters:

• Ensures product safety, reduces risk of fire or burns under fault or misuse conditions.
• Provides a presumption of conformity with EU safety objectives when cited in the Official Journal.
• Clarifies requirements for modern materials such as electro‑conductive textiles used in flexible heating appliances.

Related standards

• IEC 60335‑1 (general requirements for household appliances)
• IEC/EN 60335‑2‑17 (base publication)
• ISO 7000:2014 (graphical symbols for use on equipment)
• Relevant CENELEC/CEN harmonized standards cited in Annex ZA/ZZ

This European Standard has been prepared under a Commission’s standardization request relating to
harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonization of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
