oSIST prEN IEC 60704-2-14:2026 is a SIST standard identical to the IEC Committee Draft for Vote prEN IEC 60704-2-14:2026. It specifies particular test requirements for determining airborne acoustical noise from refrigerating appliances for household and similar use, and it is intended to be used with IEC 60704-1:2021. As a committee draft for vote, it is still under study and subject to change.

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

oSIST prEN IEC 60704-2-14:2026 applies to refrigerating appliances fitted with their accessories for household and similar use, supplied from the mains or from batteries. It is a particular part of the IEC 60704 noise test code, so it narrows the general framework in IEC 60704-1:2021 to refrigerators, frozen-food storage cabinets and food freezers.

The document is organized into clauses on scope, normative references, terms and definitions, measurement methods and acoustical environments, instrumentation, operation and location of appliances under test, sound pressure level measurement, calculation of sound power, and recording and reporting. It also includes two normative annexes.

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

Clause 2 also makes ISO 9614-1, ISO 9614-2 and ISO 9614-3 not applicable for this part.

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

Measurement methods and test environments

oSIST prEN IEC 60704-2-14:2026 allows direct and comparison methods for measuring airborne noise, using the acoustical environments described in ISO 3743-1, ISO 3743-2 and ISO 3744. In practice, this means the laboratory can use the method that fits the appliance size and the room available, as long as the test environment meets the stated criteria.

If discrete tones are audible, the document points to extra microphone or source positions under ISO 3743-1 or ISO 3743-2. That matters because tonal noise can make the measurement less stable and may require a denser measurement pattern.

Instrumentation and operating conditions

oSIST prEN IEC 60704-2-14:2026 requires temperature to be measured with instruments of specified accuracy, and the appliance has to be prepared as it would be for intended use. Loose accessories inside the cabinet are to be secured if they could vibrate unusually, doors or lids are to be closed, and adjustable feet are to be set for minimum noise emission.

Before measurement, the appliance runs in for a defined period and then reaches steady state. It is operated empty, user-adjustable openings between compartments are closed, and additional functions such as ice makers are not operated. A water supply, if any, is not connected.

Measurement sequence and result

oSIST prEN IEC 60704-2-14:2026 measures the A-weighted time-averaged sound pressure level over running periods, with special handling for aperiodic behaviour and for appliances with more than one compressor or cooling system. The practical effect is that the test must follow the operating cycle of the appliance, not just take a single fixed reading.

The final sound power result is obtained by averaging the individual measurements according to the method given in Clause 8.101. The document also defines what information is to be recorded and reported, including compartment internal temperatures averaged during the measurement.

Built-in and under-counter appliances

oSIST prEN IEC 60704-2-14:2026 gives special mounting instructions for appliances intended to be built in or placed under a counter or worktop. These appliances are tested in the test enclosure of Annex B, with a back plane and, where required, a base shelf and ventilation openings arranged according to the manufacturer’s instructions.

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

• running period - the operating interval from compressor or cooling-system start until one of them stops.
• accessory - a removable part intended to be loaded by foodstuff.
• steady state - the condition where the compartment temperatures stay within the stated tolerances, or change only slightly over hourly intervals in aperiodic behaviour.
• refrigerating appliance - an insulated cabinet with one or more temperature-controlled compartments, cooled by one or more energy-consuming means.
• aperiodic behaviour - operation without a clear running period, where the compressor or cooling system runs for a long time.
• A-weighted time-averaged sound pressure level - the sound level quantity used for the measurement result in the running periods.

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

oSIST prEN IEC 60704-2-14:2026 is used by acoustic test laboratories, appliance manufacturers, and conformity assessment teams working on household refrigerating appliances. It is also relevant to quality managers and buyers who need comparable noise data for product selection, development testing, or declared noise emission values.

The scope and procedures fit refrigerators, frozen-food storage cabinets, food freezers, and similar appliances supplied from mains or batteries. The document is especially useful where the test setup, operating state, and reporting must be repeatable across laboratories.

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

oSIST prEN IEC 60704-2-14:2026 is the third edition and it cancels and replaces the second edition and its amendments. The document states these significant changes:

• alignment to IEC 60704-1:2021
• redefinition of the measurement period, especially for appliances with two or more cooling systems
• exclusion of ice makers and other auxiliaries
• addition of a test enclosure with base shelf and additional ventilating openings

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

oSIST prEN IEC 60704-2-14:2026 is intended to be used with IEC 60704-1:2021, which provides the general requirements for the airborne-noise test code. It also points to IEC 60704-3 for the declaration and verification of noise emission values.

For measurement environments, the document refers to ISO 3743-1, ISO 3743-2 and ISO 3744. ISO 3744 is usable for sources of any size, while ISO 3743-1 and ISO 3743-2 may require extra microphone or source positions when discrete tones are present.

The bibliography also names IEC 62552-1, IEC 62552-2 and IEC 62552-3 for refrigerating appliances’ characteristics, performance, energy consumption and volume.

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

The document contains the clause-by-clause measurement procedure, the operating conditions for the appliance under test, and the calculation method for the final sound power result. It includes two tables for uncertainty and declaration/verification data, and Annex B with the test enclosure arrangement.

Figure B.101 shows the enclosure with the base shelf, skirting board, supports and additional ventilation openings. These parts are used for laboratory testing of built-in and under-counter appliances, and the reporting clauses specify what temperature data must be captured and reported with the noise result.

44 FOREWORD
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.
79 International Standard IEC 60704-2-14 has been prepared by subcommittee 59M:
80 Performance of electrical household and similar cooling and freezing appliances, of IEC
