Overview

IEC PAS 60704-2-15:2008 is a Publicly Available Specification from the IEC that defines particular requirements for the measurement of airborne acoustical noise emitted by single‑unit household food waste disposers. Intended to be used in conjunction with IEC 60704-1 (Part 1: General requirements), this PAS covers disposers for cold water supply, permanently connected to water and sewage systems, and installed under a kitchen sink in a cabinet enclosure. The July 2012 corrigendum is included in this edition.

Key topics and technical requirements

• Scope and use: Applies to single‑unit electric food waste disposers for household and similar use; does not cover declaration procedures (see IEC 60704-3 for declared values).
• Measurement methods: Supports direct and comparison methods; ISO 3743‑1, ISO 3743‑2 and ISO 3744 may be used for noise measurement. Notes on handling pure tone components are included.
• Test environment & enclosure: Specifies test enclosure geometry and the requirement for a vertical reflecting plane for appliances intended to sit against a wall or cabinet. Acoustic absorption limits and minimum clearances are defined.
• Instrumentation & procedures: References general instrumentation in IEC 60704-1; includes specific operational and measurement steps for disposers.
• Operational cycle & test loads:
  • Defines operational cycle and batch-feed operation.
  • Standard “hard” test load: fifteen 12.7 mm (0.5 in) nylon 6/6 balls (conditioned by soaking 7 days).
  • Standard “soft” test load: 200 g of baby carrots.
  • Grinding operation and measurement timing: a 10 s measurement must encompass the start of the cycle.
• Preconditioning & trials: Run 10 complete 30 s operational cycles with the hard load before measurements. Perform three trials per load with at least 5 minutes of cold water flow between trials.
• Supply conditions: Water temperature 4 °C to 27 °C; flow rate 6 ± 0.3 L/min; rules for voltage measurement and faucet positioning are specified.
• Reporting: Requirements for recorded and reported information align with the Part 1 test code, with Part 2‑15 additions.

Applications and who uses it

• Product engineers and acoustic test laboratories measuring noise performance of household food waste disposers.
• Manufacturers validating design changes, performing quality control, or preparing noise test reports for R&D and regulatory support.
• Test houses performing comparative noise testing for product development or procurement specifications.
• Standards committees and compliance professionals referencing accepted test methods for airborne noise of kitchen appliances.

Related standards

• IEC 60704-1 (general test code for airborne acoustical noise)
• IEC 60704-3 (declaration and verification of noise emission values)
• ISO 3743‑1 / ISO 3743‑2 / ISO 3744 (acoustic measurement methods)
• ANSI/ASME A112.19.3-2000 (stainless steel plumbing fixtures - sink specification referenced)

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

This Part 2-15 is intended to be used in conjunction with the second edition (1997) of IEC
60704-1: Household and similar electrical appliances – Test code for the determination of
airborne acoustical noise – Part 1: General requirements.
This Part 2-15 supplements or modifies the corresponding clauses in IEC 60704-1. When a
particular subclause of Part 1 is not mentioned in this Part 2-15, that subclause is applicable
as far as reasonable. Where this PAS states “addition”, “modification” or “replacement”, the
relevant requirements, test specifications or explanatory matter in Part 1 should be adapted
accordingly.
Subclauses or figures that are additional to those in Part 1 are numbered starting from 101.
Additional annexes are lettered AA, BB, etc.
Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.
The contents of the corrigendum of July 2012 have been included in this copy.

INTRODUCTION
The measuring conditions specified in this proposed test code provide for sufficient accuracy
in determining the noise emitted, and comparing the results taken by different laboratories,
whilst simulating as far as possible the practical use of food waste disposers.
It is recommended to consider the determination of noise levels as part of a comprehensive
testing procedure covering many aspects of properties and performance of food waste
disposers.
NOTE As stated in the introduction to IEC 60704-1, this test code is concerned with airborne noise only.
