IEC C 60519-1:2020 pdf free.Safety in installations for electroheating and electromagnetic processing – General requirements.
This risk assessment shall be expanded and specified accordingly throughout thedevelopment of the Particular requirements of lEC 60519(all parts).
The risk assessment in Annex A covers a very broad cluster of equipment and installations,therefore it is quite generic and may not cover specific origins,particular hazardous situationsor events,or potential consequences in the details deemed necessary by the manufacturer.The manufacturer shall then add to this risk assessment the specifics of his technicalsolution as specified in lsO 12100:2010.
lf the manufacturer intends to make an equipment or installation not fully under the scope ofthis document and its risk assessment,or if the Particular requirement is outdated and notreferring to this document or no Particular requirement exists, he is advised to reconsider therisk assessment in Annex A. This document then assists with the risk assessment and riskreduction procedure as specified in lsO 12100:2010.
6.1.1 The EH or EPM installation or equipment shall be suitable for its intended use,itshall be designed to be operated,adjusted and maintained without putting persons at risk.Design and construction shall ensure adequate reduction of the risks during normaloperation or in single fault condition, at the state of the art and considering the foreseeablelifetime of the EH or EPM installation or equipment.
Any risk through the workload when the workload is processed as intended in the EH or.EPM installation and that is foreseeable to the manufacturer shall be adequately reduced.
The EH or EPM installation or equipment shall be designed to prevent or to reducethe possibility of misuse or fault condition.
The EH or EPM installation or equipment shall not pose a risk of the immediate ornon-perceivable types,unless the intended use is otherwise impossible to achieve.Additionalprotective measures, warnings and instructions shall be provided in such cases.
The EH or EPM installation or equipment shall be capable of operating safely whenthe relative humidity does not exceed 50 % at a maximum temperature of 40 C. Higherrelative humidity is permitted at lower temperatures (e.g. less than 90 % at 20°C).The EH orEPM installation or equipment shall either be able to operate safely if condensationhappens occasionally or the manufacturer shall avoid condensation by design or, wherenecessary, by additional measures (e.g. built-in heaters, air conditioners or drain holes).
The EH or EPM installation or equipment shall be capable of operating safely at airpressure expected at up to 1 000 m altitude and under a wide range of climate and weatherconditions.The lower ambient pressure limit shall be 85 % of normal sea-level atmosphericpressure, unless agreed differently between the manufacturer and the user and specified inthe instructions for use.
For equipment intended to be used at higher altitudes or lower air pressure, it is necessary totake into account the reduction of the dielectric strength,the switching capability of thedevices and the reduction of the cooling effect of the air caused by reduced density.
The electrical equipment of the EH or EPM installation or equipment shall beadequately protected against the ingress of solids and liquids according to 11.3 ofIEC 60204-1:2016 for LV equipment. lt shall be adequately protected against contaminants(e.g. dust,acids, corrosive gases or salts) that can be present in the physical environment forwhich it is intended.
When the EH or EPM installation or equipment or parts of it are exposed toradiation (e.g. MW,UV, laser or X-ray), additional measures shall be taken to avoidmalfunctioning of the equipment, accelerated deterioration of the insulation,metaldegradation or corrosion due to radiation induced effects.IEC 60519-1 pdf download.
