BS EN 62885-3:2015 pdf free download Surface cleaning appliances Part 3: Wet carpet cleaning appliances — Methods for measuring the performance
1Scope
This part of lEC 62885 is applicable to wet cleaning appliances for household use for carpetcleaning in or under conditions similar to those in households. This part of lEC 62885 is notapplicable to steam cleaning vacuums.
The purpose of this standard is to:
specify the essential performance characteristics of wet cleaning appliances being ofinterest to users
describe methods for measuring these characteristics and
– be complementary to the methods for dry vacuum cleaners in IEC 60312-1.
NOTE Due to influence of environmental conditions, variations in time, origin of test materials and proficiency ofthe operator,most of the described test methods will give more reliable results when applied for comparativetesting of a number of appliances at the same time, in the same laboratory and by the same operator.
See lEC 60335-1 and lEC 60335-2-2 for safety requirements.
Wet hard floor tests are under consideration and are intended to be published in a separatestandard.

3Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
cleaning head
plain nozzle or a brush attached to a connecting tube,or a power nozzle,separate or part ofthe appliance housing, and that part of a vacuum cleaner which is applied to a surface to becleaned
[SOURCE:IEC 60312-1:2010,3.3]
3.2
active nozzle
cleaning head provided with an agitation device to assist dirt removal
Note 1 to entry: The agitation device may be driven by an incorporated electric motor (motorized nozzle), anincorporated turbine powered by the air flow (air-turbine nozzle) or an incorporated friction or gear mechanismactuated by moving the cleaning head over the surface to be cleaned (mechanical nozzle).
[SOURCE: IEC60312-1:2010,3.4]
3.3
self-propelled cleaning head
cleaning head provided with a propulsion mechanism
3.4
extractor
wet cleaning appliance with the cleaning head forming an integral part of or directly connectedto the cleaner housing, the cleaning head may be provided with an agitation device to assistdirt removal and the complete cleaner housing being moved over the surface to be cleaned bymeans of an attached handle
3.5
forward stroke
forward movement of a stroke pattern
Note 1 to entry: On test carpets,forward strokes are normally carried out in the direction of the carpet pile(direction of manufacture) unless otherwise indicated.
[SOURCE:IEC 60312-1:2010,3.15]
3.6
return stroke
backward movement of a stroke pattern
[SOURCE:IEC60312-1:2010,3.16]
3.7
stroke speed
speed of the cleaning head,moved as uniformly as possible,during a forward or a returnstroke
[SoURCE:IEC60312-1:2010,3.12]
3.8
stroke length
distance between the two parallel lines defining the limits of a stroke pattern
3.9
stroke pattern
arrangement of the forward and return strokes on the surface to be cleaned
[SOURCE: IEC 60312-1:2010,3.10]
3.10
cleaning cycle
for a given measurement, the sequence of forward and return strokes to be carried out at aspecified stroke speed over the test area according to the appropriate stroke pattern
3.11
wet cleaning appliance
electrically operated appliance that applies cleaning solution and removes soil together withsolution from the surface to be cleaned by an airflow created by a vacuum developed withinthe unit
Note 1 to entry: The material and solution thus removed is separated in the appliance and the cleaned dry suctionair is returned to the ambient.
3.12
passive nozzle
cleaning head without any agitation devices
[SOURCE: IEC 60312-1:2010,3.5]
3.13
cleaning head width
external maximum width of the cleaning head in millimetres
[SOURCE: IEC 60312-1:2010,3.7, modified – “metres” has been replaced by “millimetres”.]
3.14
steam vacuum cleaner
electrically operated appliance producing wet steam heat (steam generated from water onlyor a water solution mix) to moisten an absorbent pad for surface removal of soil stains
