1 Scope
This clause of GB 4706.1-2005 is replaced by the following:
This part deals with the safety of electric washing machines for household and similar use, that are intended for washing clothes and textiles, their rated voltage being not more than 250V for single-phase appliances and 480V for other appliances.
This part also deals with the safety of electric washing machines for household and similar use employing an electrolyte instead of detergent. Additional requirements for these appliances are given in Annex CC.
Note 101: guidance is given in Annex DD for requirements that may be used to ensure an acceptable level of protection against electrical and thermal hazards for washing machines fitted with a power driven wringer.
Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.
Note 102: examples of such appliances are washing machines for communal use in blocks of flats or in launderettes.
As far as is practicable, this part deals with the common hazards presented by washing machines that are encountered by all persons in and around the home. However, in general, it does not take into account
——persons (including children) who
lack of physical, sensory or mental capabilities; or
lack of experience and knowledge
prevents them from using the appliance without supervision or instruction;
children playing with the appliance.
Note 103: attention is drawn to the fact that
——for washing machines intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary;
——in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labor, the national water supply authorities and similar authorities.
Note 104: this standard does not apply to
——washing machines intended exclusively for industrial purposes (ISO 10472-2);
——appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapor or gas).

3 Terms and Definitions
For purpose of this part, the following terms and definitions apply.
This clause of GB 4706.1-2005 is applicable except as follows.
3.1.9 Replacement:
normal operation
operation of the appliance under the following conditions:
The appliance is filled with dry textile material having a mass equal to the maximum mass stated in the instructions, and with the maximum quantity of water for which it is constructed. However, if the power input or current is higher when only 50% of the textile material is used, the appliance is operated with this load instead if this gives more unfavorable conditions than the full load during the test of Clause 11.
Note 101: for some appliances incorporating a programmer, using the 50% reduced load may result in automatic selection of a reduced wash programme.
The temperature of the water is
——50±5℃ for appliances without heating elements;
——15±5℃ for appliances without heating elements and intended for connection to the cold water supply only;
——15±5℃ for other appliances.
If the appliance does not incorporate a programmer, the water is heated to 90±5℃ or as high as the construction will allow if lower, before starting the first washing period.
The textile material consists of pre-washed double-hemmed cotton sheets having dimensions approximately 700mm×700mm and a specific mass between 140~175g/m2 in the dry condition.
For impeller type washing machines, if the textile material does not move properly during operation,
the quantity of textile material may be reduced until the maximum power input of the motor is attained, or
a textile material comprising pre-washed double-hemmed cotton sheets, having dimensions of approximately 900mm×900mm and a mass between 90~110g/m2 in the dry condition, may be used.
However, for impeller type washing machines, in case of doubt, the test is carried out using the reduced quantity of textile material.
