This clause of Part 12 is applicable except as follows:

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

- intended for RADIOTHERAPY in human medical practice, including those in which the selection and DISPLAY of operating parameters can be controlled automatically by PROGRAMMABLE ELECTRONIC SUBSYSTEMS (PESS)

- that, under NORMAL CONDITIONS and in NORMAL USE, deliver a RADIATION BEAM of XRADIATION and/or ELECTRON RADIATION having

- NOMINAL ENERGY in the range 1 MeV to 50 MeV

- maximum ABSORBED DOSE RATES between 0,001 Gy × s-1 and 1 Gy × s-1 at 1 m from the RADIATION SOURCE

- NORMAL TREATMENT DISTANCES (NTDs) between 0,5 m and 2 m from the RADIATION SOURCE and

- intended to be

- for NORMAL USE, operated under the authority of appropriately licensed or QUALIFIED PERSONS by OPERATORS having the required skills for a particular medical application, for particular specified clinical purposes, e.g. STATIONARY RADIOTHERAPY or MOVING BEAM RADIOTHERAPY

 

- maintained in accordance with the recommendations given in the INSTRUCTIONS FOR USE

 

- subject to regular quality assurance performance and calibration checks by a QUALIFIED PERSON.

 

NOTE 1 In this particular standard, all references to installation refer to installation in the RESPONSIBLE

ORGANIZATION'S premises.

 

NOTE 2 In this particular standard, all references to ABSORBED DOSE refer to ABSORBED DOSE in water.

 

IEC 61271 gives guidance on the designation of ME EQUIPMENT movements; the marking of scales, their zero positions and the direction of movement with increasing value (see 201.7.4.101).

 

IEC 60676 specifies methods of testing and disclosure of functional performance of medical ELECTRON ACCELERATORS. The standard is intended to facilitate comparisons of acceleratorbased ME EQUIPMENTs of different manufacture. IEC 60676 contains no safety requirements, and is therefore not required for compliance with this particular standard. It should also be noted (as stated in the Introduction to IEC 60976:2007) that tests specified in IEC 60976 are not necessarily appropriate for ensuring that any individual medical ELECTRON ACCELERATOR conforms to the declared functional performance during the course of its working lifetime.

 

NOTE 3 IEC/TR 60977, Medical electrical equipment - Medical electron accelerators - Guidelines for functional performance characteristics, is a related technical report that provides performance guidelines. It shall not be construed as a standard.
