Overview
IEC 60299:2014 – Household Electric Blankets: Methods for Measuring Performance, developed by the International Electrotechnical Commission (IEC), establishes standardized methods for evaluating the performance of electric blankets, wraps, and duvets intended for household use. This international standard outlines the primary performance characteristics and describes procedures for measuring these characteristics, helping users, manufacturers, and testing laboratories assess electric blanket products consistently. Safety requirements are addressed separately under IEC 60335-2-17.
Key Topics
Classification of Electric Blankets
IEC 60299:2014 introduces an extended classification system for household electric blankets, wraps, and duvets, including:
- Type: Underblanket, overblanket, wrap, or duvet
- Heated areas: Single or double blankets with one or two heated zones
- Temperature distribution: Uniform, non-uniform, or high-temperature zone types
- Means of control: Non-controlled or controlled appliances with various control features
- Regulation: With or without controls, including variable, step, or ambient compensation settings
- Type of supply: Direct mains connection or extra low voltage (≤24 V)
- Cleaning method: Hand washable, machine washable, or non-washable
- Fixing method: With or without tie tapes or fitted underblankets
Performance Measurement Methods
The standard specifies objective and repeatable methods for assessing performance characteristics, including:
- Dimensions, mass, and textile composition: Accurate measurement of size and fabric makeup
- Evenness of temperature: Evaluation of temperature distribution using thermocouples and standardized copper plates
- Heating-up time and energy consumption: Timed evaluation from cold start to target temperature and associated energy use, including standby consumption
- Stability of temperature: Assessment of temperature consistency under varying conditions, especially for controlled appliances
- Effect of laundering: Measurement of dimensional changes after washing to determine shrinkage or stretching
- Control settings: Documentation of functional settings for temperature and timing
Notably, this edition updates temperature measurement methods to use thermocouples for improved accuracy.
Applications
IEC 60299:2014 is widely applicable to:
- Manufacturers: Product development, quality assurance, and performance benchmarking of household electric blankets and similar flexible heating products.
- Testing laboratories: Consistent product evaluation and verification services as part of international and regional conformity assessment programs.
- Retailers and distributors: Assessing product claims regarding energy efficiency, heating performance, and durability after laundering.
- Consumers: Informed decision-making based on standardized and transparent product information.
- Regulatory bodies: Supporting market surveillance and product safety enforcement by providing harmonized test methods.
The consistent application of this standard helps ensure accurate product comparison, reliable consumer information, and supports regulatory compliance across jurisdictions.
