IEC 60335-2-14:2016

Overview

IEC 60335-2-14:2016 is the International Electrotechnical Commission (IEC) standard that specifies safety requirements for electric kitchen machines for household and similar purposes. The standard ensures that kitchen machines with rated voltages up to 250 V are safe for use in homes, small shops, light industry, and farms. It addresses common hazards associated with typical kitchen appliances encountered in domestic and similar settings, providing a globally recognized benchmark for both manufacturers and testing organizations.

This standard is part of the IEC 60335 series on household electrical appliance safety and is intended for use in conjunction with IEC 60335-1, General Requirements. The latest edition includes significant technical updates to address safety for new appliance types and usage scenarios.

Key Topics

• Scope of Application: IEC 60335-2-14 covers household kitchen machines such as blenders, food mixers, juicers, food processors, mincers, noodle makers, potato peelers, shredders, and similar devices. It explicitly excludes industrial and commercial kitchen machines, food waste disposers, and certain specialized appliances.

• Safety Provisions: The standard establishes requirements to protect users from electrical, mechanical, thermal, fire, and radiation hazards. It considers normal and reasonably foreseeable abnormal use, and includes provisions for mechanical strength, protection against electric shock, and safe construction.

• Marking and Instructions: Manufacturers must provide clear markings for rated power input and clear user instructions, specifically including operating times, safe use of accessories, and safety warnings for sharp components and hot liquids.

• Testing and Compliance: IEC 60335-2-14 outlines procedures for product testing, including methods for heating, overload protection, leakage current, and endurance. National authorities may require additional tests depending on local regulations.

• Recent Updates: The 2016 edition introduces requirements for noodle makers, updates handling of appliances with feed screws or augers, revises the definition of normal operation, changes heating test methods, and upgrades several notes to normative requirements.

Applications

IEC 60335-2-14 is widely utilized by:

• Appliance Manufacturers: To design and produce safe kitchen machines compliant with international safety benchmarks, ensuring broader market access and lower risk of product recalls.
• Testing and Certification Bodies: As a basis for conformity assessments, certification, and regulatory approval of appliances before reaching consumers.
• Regulators and Importers: To verify that kitchen machines meet essential safety requirements for entry into national or regional markets.
• Retailers and Distributors: To ensure due diligence in product sourcing and to minimize liability associated with unsafe appliances.

Typical Appliances Covered

• Blenders and liquidizers
• Food processors
• Mixers and choppers
• Centrifugal and citrus juicers
• Electric knives and sharpeners
• Graters, shredders, and slicers
• Mincers and noodle makers
• Potato peelers

Appliances intended for professional, industrial, or hazardous locations (e.g., environments with explosive atmospheres) are outside the scope.

Related Standards

For complete compliance and broader context, reference the following related standards:

• IEC 60335-1: Safety of household and similar electrical appliances - General requirements (mandatory for use with Part 2-14)
• IEC 60335-2-16: Particular requirements for food waste disposers
• IEC 60335-2-24: Particular requirements for refrigerating appliances, ice-cream appliances with incorporated motor-compressors
• IEC 60335-2-64: Particular requirements for commercial electric kitchen machines
• IEC 60811 Series: Test methods for electric and optical fibre cables (for non-metallic materials used in appliances)

Summary

IEC 60335-2-14:2016 serves as a vital international standard for the safety of electric kitchen machines in household and similar settings. By adhering to this standard, manufacturers and stakeholders can ensure product safety, enhance consumer protection, and facilitate international trade in kitchen appliances. For full compliance, use this part of IEC 60335 in conjunction with Part 1 and remain attentive to relevant national regulations and amendments.
