IEC 60704-2-1:2014 applies to electrical vacuum cleaners (including their accessories and their component parts) for household use in or under conditions similar to those in households. This part of IEC 60704 applies as it is to electrical vacuum cleaners operating in dry conditions. Some additions and modifications for vacuum cleaners operating in wet conditions are under consideration. How to test robotic vacuum cleaners is under consideration for a future edition. This part of IEC 60704 does not apply to vacuum cleaners for industrial or professional purposes. This third edition cancels and replaces the second edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) introduction of a measuring method on hard floors;
b) inclusion of values for measurement uncertainty;
c) inclusion of values for standard deviation for declaration and verification;
d) update of the definition of the standard test carpet.

This publication is to be read in conjunction with IEC 60704-1:2010.
