Comprehensive Guide to ISO 14257 Acoustic Noise from Household Equipment Laboratory Testing Service by Eurolab

Standard-Related Information

ISO 14257 is a globally recognized standard that specifies the requirements for measuring and evaluating the acoustic noise generated by household equipment, such as washing machines, dishwashers, refrigerators, and air conditioners. The standard aims to ensure that these products meet certain sound level limits, thereby reducing the impact of noise pollution on consumers.

International and National Standards

The ISO 14257 standard is part of a larger family of standards related to noise measurement, including:

  • ISO 3741: Determination of sound power levels of noise sources using sound pressure measurements in reverberant fields

  • ISO 9614-2: Determination of sound power levels of noise sources using sound intensity measurements

    • In addition to international standards, many countries have their own national regulations and guidelines for noise measurement. For example:

  • European Unions Directive 2009/28/EC on the minimum energy performance requirements for household appliances

  • US Environmental Protection Agencys (EPA) Noise Reduction Act of 1972

  • Japans Ministry of Economy, Trade and Industrys (METI) Technical Standard for Household Appliances
