IEC 60704-2-1:2020 is available as IEC 60704-2-1:2020 RLV<\/span> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.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.<\/p>\n
