Description (English):

IEC 60704-2-14:2013 specifies the measuring conditions to provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of household refrigerators, frozen-food storage cabinets and food freezers. It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of household refrigerators, frozen-food storage cabinets and food freezers. This edition includes the following significant technical changes with respect to the previous edition: a) the description of an appropriate test enclosure has been removed from this part of IEC 60704 and has been incorporated into Part 1 of IEC 60704-1; b) the values of standard deviations of sound power levels determined according to this part of IEC 60704 have been added. This publication is to be read in conjunction with IEC 60704-1:2010.

Abstract

Overview

IEC 60704-2-14:2013 is the International Electrotechnical Commission test code that defines particular requirements for measuring airborne acoustical noise from household refrigerators, frozen‑food storage cabinets and food freezers. This Part 2-14 supplements IEC 60704-1:2010 (general requirements) and is intended to produce accurate, reproducible sound power and sound pressure measurements that simulate practical use conditions. The edition consolidates test-enclosure guidance into Part 1 and adds quantified standard deviations for measurement uncertainty.

Key topics and technical requirements

Scope: Applies to household refrigerators, frozen‑food storage cabinets and food freezers (mains or battery) - airborne noise only, appliances tested without an operator present.
Measurement methods: Direct and comparison methods as per ISO 3743‑1, ISO 3743‑2 and ISO 3744; microphone arrays and measurement surfaces for free‑field-over‑reflecting‑plane conditions are referenced.
Pre‑conditioning and operation:
- Equip appliance as intended for use; fix loose accessories to avoid unusual vibration.
- Running‑in: at least 16 h at specified ambient temperature.
- Measurements after steady state achieved and at least three complete compressor running periods.
Instrumentation and environment:
- Temperature measurement accuracy: ±0.5 °C.
- Consideration of climatic conditions, electrical supply, mounting and loading to simulate normal use.
- Pure tones may increase measurement scatter; additional microphone/source positions may be required (see ISO guidance).
Measurement uncertainty:
- Repeatability r = 0.4 dB, Reproducibility R = 0.7 dB (sound power).
- For declaration and verification (IEC 60704‑3 context): production σP 0.7–1.5 dB, total σt 1.0–1.7 dB, reference σM 2.0 dB.

Practical applications and users

Who uses IEC 60704-2-14:

Manufacturers for product design, noise optimization and internal quality control.
Independent test laboratories and accredited acoustics labs to perform standardized noise measurements and compare results across sites.
Certification bodies and compliance engineers verifying product acoustic performance.
Acoustic consultants assessing appliance noise in consumer and environmental contexts.

Typical uses:

Verification of declared noise emission values (used alongside IEC 60704‑3),
Development testing to reduce perceived noise,
Comparative laboratory testing for product benchmarking,
Supporting regulatory or labeling programs that require standardized acoustical data.
