prEN IEC 60704-2-14:2026 is a draft IEC/CENELEC test code for determining airborne acoustical noise from household and similar refrigerating appliances. It specifies how to measure and report the sound emitted by refrigerators, frozen-food storage cabinets and food freezers, for use by test laboratories, manufacturers and others who need comparable noise data.

What does prEN IEC 60704-2-14:2026 specify?

prEN IEC 60704-2-14:2026 gives particular requirements for the noise test of refrigerating appliances supplied from the mains or from batteries. It supplements IEC 60704-1:2021, so the general test code is used together with this part and adapted where this part adds, replaces or modifies requirements.

The document is organized into clauses on scope, normative references, terms and definitions, measurement methods, instrumentation, appliance preparation, sound pressure level measurement, calculation, recording and reporting. It also includes two normative annexes that support the test set-up.

Annex	What it covers
Annex A	Standard test table
Annex B	Test enclosure

The scope applies to refrigerating appliances fitted with their accessories for household and similar use. Air conditioners are outside the scope.

What are the key requirements of prEN IEC 60704-2-14:2026?

prEN IEC 60704-2-14:2026 focuses on getting repeatable noise measurements from real refrigerating appliances under controlled conditions. The most important requirements are about the test room, how the appliance is operated, and how the result is calculated.

• Choice of measurement method - Clause 4 allows direct and comparison methods, using ISO 3743-1, ISO 3743-2 or ISO 3744 for the acoustical environment. In practice, this means the laboratory must choose a room and method that fit the appliance size and the noise source, and add microphone or source positions if discrete tones affect repeatability.

• Measurement uncertainty - Clause 4.5 replaces the uncertainty treatment with standard deviations for sound power levels and for declaration and verification. This matters when comparing laboratories or declaring a noise emission value, because the same measured result can be interpreted differently depending on the variability used.

• Instrumentation - Clause 5 requires temperature to be measured with instruments of specified accuracy. That matters because appliance operating temperature is part of the test condition, not just background information.

• Preparation before testing - Clause 6 requires loose accessories that could vibrate to be secured, doors or lids to be closed, and adjustable feet set to minimize noise. It also requires a running-in period of at least 16 h before noise measurements. In practice, the appliance has to be set up as it will be used, not as an unpacked unit.

• Operating condition during the test - Clause 6 requires the appliance to run empty, with user-adjustable openings closed and additional functions such as ice makers not operated. Defrosting is not treated as normal operation, and measurements around defrosting are excluded. This keeps the result tied to the normal noise of cooling, not to special cycles.

• Test temperatures and room conditions - Clause 6 defines the ambient conditions and the compartment temperature targets for fresh-food, frozen, chill, wine storage, cellar, pantry and variable-temperature compartments. The internal temperatures are checked with probes placed in solid metal cylinders at the compartment center, so the declared noise level reflects the appliance running at its intended setting.

• How sound is measured - Clause 7 requires A-weighted time-averaged sound pressure level measurements over the running period. For appliances with more than one compressor or cooling system, the relevant running periods are identified and the loudest ones are measured. This is important for appliances whose noise changes from cycle to cycle.

• How the final result is formed - Clause 8 calculates the final sound power level from the individual measurements. For the user, that means the reported result is not a single spot reading but a controlled combination of repeated measurements.

What terms does prEN IEC 60704-2-14:2026 define?

prEN IEC 60704-2-14:2026 defines the terms needed to apply the test correctly.

• Running period - the interval from the start of compressor or cooling-system operation until at least one of them stops.
• Accessory - a removable part intended to be loaded with foodstuff.
• Steady state - the condition where compartment temperatures have stabilized within the stated tolerance.
• Refrigerating appliance - an insulated cabinet with one or more temperature-controlled compartments for household use.
• Aperiodic behaviour - operation with no specific running period, where the compressor or cooling system runs for longer than 4 h.

Who uses prEN IEC 60704-2-14:2026?

prEN IEC 60704-2-14:2026 is used by test laboratories that measure airborne noise from refrigerators and similar appliances. It is also used by manufacturers, product engineers and quality teams that need comparable noise data for design checks, product claims and internal verification.

The document is relevant to organizations working with household refrigerating appliances, including free-standing, portable, wall-mounted and built-in types. It also supports buyers and technical evaluators who need to compare noise results from different laboratories under the same test code.

What changed in prEN IEC 60704-2-14:2026 from the previous edition?

prEN IEC 60704-2-14:2026 cancels and replaces the second edition and its amendments. The document states these main technical changes: alignment to IEC 60704-1:2021, a redefinition of the measurement period for appliances with two or more cooling systems, exclusion of ice makers and other auxiliaries, and the addition of a test enclosure with a base shelf and extra ventilating openings.

Which standards are used with prEN IEC 60704-2-14:2026?

prEN IEC 60704-2-14:2026 is intended to be used with IEC 60704-1:2021, which provides the general requirements for the airborne acoustical noise test code. It also refers to IEC 60704-3 for determining and verifying declared noise emission values.

The acoustical test environment can use ISO 3743-1, ISO 3743-2 and ISO 3744. ISO 9614-1, ISO 9614-2 and ISO 9614-3 are stated as not applicable for this part.

What does the prEN IEC 60704-2-14:2026 document contain?

prEN IEC 60704-2-14:2026 contains the practical framework for measuring airborne acoustical noise from refrigerating appliances: the test methods, the appliance operating conditions, the measurement sequence, the calculation of the final result, and the information to record and report. It also includes a normative standard test table and a normative test enclosure, with a figure showing a base shelf and additional ventilating openings.

The document is structured so that a laboratory can prepare the appliance, run the measurements, and report a comparable sound power level without relying on unsupported local practice.

45 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
46 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
47 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
48 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
49 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
50 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
51 in the subject dealt with may participate in this preparatory work. International, governmental and non -
52 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
53 with the International Organization for Standardization (ISO) in accordance with conditions determined by
54 agreement between the two organizations.
55 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
56 consensus of opinion on the relevant subjects since each technical committee has representation from all
57 interested IEC National Committees.
58 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
59 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
60 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
61 misinterpretation by any end user.
62 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
63 transparently to the maximum extent possible in their national and regional publications. Any divergence
64 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
65 the latter.
66 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
67 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
68 services carried out by independent certification bodies.
69 6) All users should ensure that they have the latest edition of this publication.
70 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
71 members of its technical committees and IEC National Committees for any personal injury, property damage or
72 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
73 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
74 Publications.
75 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
76 indispensable for the correct application of this publication.
77 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
78 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
