Description (English):

IEC 60704-2-1:2020 is applicable for the determination of airborne acoustical noise of mains operated and cordless dry vacuum cleaners for household use or under conditions similar to those in households. This part of IEC 60704 does not apply to vacuum cleaners for industrial or professional purposes. This edition includes the following significant technical changes with respect to the previous edition: a) product scope is extended to cordless and similar vacuum cleaners; b) definitions of "cleaning head", "active nozzle" and "standard Wilton test carpet" have been added; c) specification of standard Wilton test carpet has been removed; reference is made to IEC/TS 62885-1; d) specific requirements on equipping and pre-conditioning have been added; e) topic ageing of test carpet is addressed. This Part 2-1 supplements or modifies the corresponding clauses in IEC 60704-1:2010.

Abstract

Overview - IEC 60704-2-1:2020 (dry vacuum cleaners, airborne acoustical noise)

IEC 60704-2-1:2020 is the International Electrotechnical Commission test code that specifies particular requirements for determining airborne acoustical noise of mains-operated and cordless dry vacuum cleaners intended for household use (or under similar conditions). It supplements and modifies the general requirements in IEC 60704-1:2010 and is focused on reproducible measurement of sound emissions for product development, comparison and declaration.

Key scope points:

Applies to dry vacuum cleaners for household use (mains and cordless); excludes industrial/professional machines.
Covers noise measurement on carpet and hard floor surfaces, under conditions simulating normal use.
Concerned with airborne noise only (not structure-borne noise).

Key topics and technical requirements

Measurement methods: ISO 3743-1, ISO 3743-2 and ISO 3744 may be used; ISO 3744 is applicable to sources of any size.
Definitions added: "cleaning head", "active nozzle" and "standard Wilton test carpet".
Test carpet handling: specification of the standard Wilton test carpet removed from this Part and now referenced to IEC/TS 62885-1; ageing of test carpet and related pre-conditioning are addressed.
Equipping and pre-conditioning: new, specific requirements for preparing appliances and accessories prior to measurement.
Measurement uncertainty / standard deviations: repeatability and reproducibility estimates derived from round-robin tests:
- On carpets: repeatability r = 0.3 dB, reproducibility R = 0.8 dB.
- On hard floors: repeatability r = 0.2 dB, reproducibility R = 0.6 dB.
Declaration and verification: standard deviations for production and total uncertainty for declared noise values are provided (examples for carpets: production σP = 0.5–1.0 dB; total σt = 0.9–1.3 dB; reference σM = 1.5 dB).
Notes: a temporary “boost” setting (higher fan speed for occasional use) is not included in declared noise values.

Practical applications - who uses IEC 60704-2-1:2020

Manufacturers: for product design, R&D, and noise performance optimization of household vacuum cleaners (including cordless models).
Test laboratories and certification bodies: to perform standardized, comparable noise measurements for compliance testing and product certification.
Regulatory authorities and buyers: to verify declared sound emissions and support labeling, procurement and consumer guidance.
Quality control and production: to establish repeatable test procedures and verify production consistency against declared noise values.
