IEC 60335-2-71:2018

Overview

IEC 60335-2-71:2018 is an international safety standard published by the International Electrotechnical Commission (IEC). It outlines the particular requirements for household and similar electrical heating appliances used specifically for breeding and rearing animals. This includes electrical heating devices such as heat-radiating appliances, electrical sitting-hens, incubators, chicken breeding units, and heating plates designed for livestock. The standard addresses appliances with rated voltages not exceeding 250 V for single-phase and 480 V for other appliances, and includes those with electrical motors.

The 2018 edition is the third revision of this standard, replacing the 2002 edition and its subsequent amendments. It incorporates updated normative references, requirements for colour coding of symbols, and converts certain notes into normative text to ensure clarity and enhanced safety compliance.

Key Topics

• Scope & Application
  IEC 60335-2-71:2018 applies to electrical heating appliances intended for animal breeding and rearing in household and similar environments. It excludes industrial appliances, appliances for harsh environments like explosive or corrosive atmospheres, floor-embedded heating units, flexible sheet heating elements for room heating, and general room heaters covered under other related IEC standards.

• Safety Requirements
  The standard ensures protection against electric shock, mechanical hazards, overheating, fire, radiation, and other risks associated with heating appliances used in livestock environments. It covers general construction, mechanical strength, stability, internal wiring, component safety, and electrical insulation.

• Testing & Performance
  Detailed provisions for power input, current, leakage current, electric strength at operating temperature, moisture resistance, overload protection, endurance, and abnormal operation tests are included to verify appliance safety and reliability.

• Marking and Instructions
  Appliances must bear clear markings including colour-coded symbols for improved identification and safety, along with comprehensive user instructions relevant to their specific use in animal breeding and rearing.

• Electrical Compliance
  The standard references IEC 60335-1 as the foundational general safety standard for household appliances, supplementing it with specific clauses suited to the particular risks posed by electrical breeding and rearing appliances.

Applications

IEC 60335-2-71:2018 is essential for manufacturers, testing laboratories, and regulatory bodies involved with:

• Production and certification of electrical heating devices for livestock, such as incubators or heating plates.
• Ensuring safety conformity for electrical equipment used in poultry breeding farms.
• Designing electrically operated animal breeding appliances with integrated motors, ensuring both operational safety and protection against environmental hazards.
• Evaluating appliances used in agricultural settings where temperature control and animal welfare are critical.
• Compliance documentation supporting market access for electrical heating appliances intended for farming and animal husbandry.
