1 Scope 

This clause of Part 1 is replaced by the following. 

This International Standard deals with the safety of electric cleaning appliances for household use that are intended for cleaning surfaces such as windows, walls and empty swimming pools by using liquid cleansing agents or steam, their rated voltage being not more than 250 V. It also covers wallpaper strippers. 

NOTE 101 Appliances may incorporate heating elements or means for pressurising the liquid container. 

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account 
– persons (including children) whose 
• physical, sensory or mental capabilities; or 
• lack of experience and knowledge 
prevents them from using the appliance safely without supervision or instruction; 
– children playing with the appliance. 
NOTE 102 Attention is drawn to the fact that 
– for appliances 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 labour, and similar authorities. 

NOTE 103 This standard does not apply to 
– floor treatment and wet scrubbing machines (IEC 60335-2-10); 
– cleaning appliances that are permanently fixed to a building; 
– cleaning appliances covered by IEC 60335-2-79, namely those having a 
• pressure exceeding 2,5 MPa; 
• pressurised volume over 5 l; 
• product of pressure (in MPa) and container volume (in l) exceeding 5; 
• liquid temperature exceeding 160 °C; 
• rated power input exceeding 3 500 W;

1.1 Replacement:

This part of IEC 60730 applies to the partial evaluation of thermal motor protectors as defined in IEC 60730-1 for household and similar use, including heating, air conditioning and similar applications as well as for sealed (hermetic and semi-hermetic type) motor-compressors.

NOTE A thermal motor protector is considered an integrated control since its protective functionality is dependent on the correct mounting and fixing in or on a motor and which can only be fully tested in combination with the relevant motor. This dependency is illustrated by:

• the ability of the thermal motor protector to accurately and reliably sense the heat of the motor windings; thus, addressing the over-temperature protection due to motor overload conditions;
• the ability of the thermal motor protector to accurately and reliably sense the current due to motor locked-rotor conditions; thus, reducing the response time and not being adversely affected by heat-sink at the assembly spot in the application;
• the influence of the motor’s electromagnetic field on the switch behaviour of the thermal motor protector; particularly, affecting the arc direction between the contacts resulting in uneven wear of the contact material and eventually leading to failure of operation.

Requirements concerning the testing of the combination of sealed (hermetic and semi-hermetic type) motor-compressors and thermal motor protectors are given in IEC 60335-2-34.

This standard applies to thermal motor protectors using NTC or PTC thermistors, additional requirements for which are contained in Annex J.

1.1.1 This standard applies to the inherent safety, to the operating values, operating times, and operating sequences, where such are associated with equipment safety, and to the testing of thermal motor protectors used in or on household or similar equipment as well as sealed (hermetic and semi-hermetic type) motor-compressors.

This standard applies to thermal motor protectors for appliances within, but not limited to, the scope of IEC 60335-1 and its Part 2’s.

NOTE Throughout this standard, the word “equipment” means “appliance and equipment”.

Thermal motor protectors not intended for normal household use, but which nevertheless may be used by the public, such as equipment intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.

This standard does not apply to thermal motor protectors designed exclusively for industrial applications.

1.1.2 This standard does not apply to other means of motor protection.

1.1.3 This standard does not apply to a manual device for opening the circuit.

Replacement:

This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of ELECTRON ACCELERATORS, hereafter referred to as ME EQUIPMENT, in the range 1 MeV to 50 MeV, used for treatment of PATIENTS.

This particular standard, with the inclusion of TYPE TESTS and SITE TESTS, applies respectively to the manufacture and some installation aspects of ELECTRON ACCELERATORS
