Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz - Part 2-3: Immunity requirements for mains communicating equipment operating in the range of frequencies 3 kHz to 95 kHz and intended for use by electricity suppliers and distributors
SIST EN 50065-2-3:2024

This document applies to electrical equipment using signals in the frequency range 3 kHz to 95 kHz to transmit or receive information on low voltage electrical systems, for electricity suppliers and distributors. Mains communicating equipment (MCE) may fall into one of the two following categories: - MCE implementing transmission or reception of information on LV distribution networks or installations of network users connected to the public electricity distribution network as the sole function. Immunity requirements for such equipment are entirely covered by this document; - MCE being equipment covered by the scope of other standards, integrating mains communication as one of their functions. In this case, only the immunity requirements for the mains communication function of such equipment are covered by the scope of this document. Immunity requirements for all other available functions of this equipment are covered by the relevant product standard or generic standard. The object of this document is to contribute to ensuring EMC in general. It specifies essential immunity requirements and test methods, including those tests which are to be performed during type-testing of MCE, for electromagnetic interference (EMI) generated on LV installations. It defines the methods and requirements for testing immunity of MCE on meeting the essential requirements of the EMCD. Test requirements are specified for each port considered. Furthermore, it provides guidelines for the assessment of the performance of the communication function of an MCE. Normative specifications are under consideration. This document gives immunity requirements which are applicable to MCE used by electricity suppliers and distributors (e.g. DSOs) for purposes like energy management and network monitoring and automation. The levels do not however cover extreme cases which could occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances could exceed the levels specified in this document, e.g. where a hand-held transmitter is used in proximity of an apparatus. In these instances special mitigation measures might have to be employed. It does not specify immunity of MCE to signals from other MCE operating in the same nominal frequency band or immunity to signals originating from power line carrier systems operating on high or medium-voltage networks. Safety considerations are not included in this document.

Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz - Part 2-3: Immunity requirements for mains communications equipment and systems operating in the range of frequencies 3 kHz to 95 kHz and intended for use by electricity suppliers and distributors
SIST EN 50065-2-3:2004

This standard applies to electrical equipment using signals in the frequency range 3 kHz to 95 kHz to transmit or receive information on low voltage electrical systems, for electricity suppliers and distributors. In the case of equipment which includes functions other than the transmission or reception of information on low voltage electrical supplies, this standard applies only to that part of the equipment intended for such transmission or reception of information. Other parts of the equipment shall comply with the immunity standard or standards relevant to the functions of those other parts. In the event of tests being specified in those other standards of a different severity and where the construction of the equipment is such that the functions cannot be tested separately, the higher severity shall apply to all affected functions. The object of this standard is to limit mutual influence between mains communication equipment and systems (MCES) operating in different frequency bands as defined in EN 50065-1 and to contribute to ensuring electromagnetic compatibility in general. It specifies essential immunity requirements and test methods, including those tests which are to be performed during typetesting of MCES on low-voltage installations, for electromagnetic interference in general and more specific interference coming from other MCES. It therefore defines the immunity test requirements for apparatus in relation to continuous and transient disturbances, both conducted and radiated, and electrostatic discharges. Test requirements are specified for each port considered. This standard gives limits which are applicable to products operating in the public supply network, operated by electricity utilities. The levels do not however cover extreme cases which may occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances may exceed the levels specified in this standard e.g. where a hand-held transmitter is used in proximity to an apparatus. In these instances special mitigation measures may have to be employed. It does not specify immunity between mains communication systems operating in the same band (as defined in EN 50065-1) or immunity to signals originating from power line carrier systems operating on high or medium voltage networks. Safety considerations are not included in this standard.

Household and similar electrical appliances - Safety - Part 2-39: Particular requirements for commercial electric multi-purpose cooking pans
SIST EN IEC 60335-2-39:2025

IEC 60335-2-39:2012 deals with the safety of electrically operated commercial multi-purpose cooking pans not intended for household and similar use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. This standard also deals with pressurized appliances and appliances with pressurized parts. These appliances are used for processing food for commercial consumption, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries, butcheries, etc. The electrical part of appliances making use of other forms of energy is also within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. 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. The principal changes in this edition as compared with the fifth edition of IEC 60335-2-39 are as follows (minor changes are not listed): - addition to definition of portable appliances, atmospheric multi-purpose cooking and rated pressure; - deletion of equipotential symbol 5021 of IEC 60417 covered by Part 1; - addition of instructions for multi-purpose cooking pans; - modification on leakage current permissible for portable class l appliances; - addition to abnormal test requirements; - addition to mechanical hazard test for multi-purpose cooking pans; - addition of construction test for multi-purpose cooking pans; - addition to construction requirements for lids and theirs grips; - addition to construction requirements for positioning of pressure reliefs; - addition to construction's fixed appliances which are moved forward and backward for cleaning purposes.
The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. Keywords: Multi-purpose cooking pans.
