Hi Guys,
frequently I am following the treats on this forum and they are very helpful. I am really appreciate it, thank you. I have one question myself. I am developing a device with a heating rod. The heating rod of choice is powered with 240V. The water flowing around the heating rod has a direct contact to patient’s skin. According to the 60601-1 3th edition 8.5.1 the heating rod needs to keep 2 MOPP. The heating rod is earthed according to 8.6. This is 1 MOPP and ok so far. Furthermore the heating rod is tested according to the IEC 60335-1 (safety of household and similar electrical appliances). However unfortunately this standard does not meet the requirements of dielectric strength and clearances and creepage distances of the 60601-1 for 1 MOPP. Beyond that the heating rod provides no further MOP. Unfortunately I have not found any suitable heating rod that would provide the 60601-1 requirements So my question, how to evaluate this situation based on the definition of the 60601-1 3th edition, is this solution acceptable? Or which additional MOP may be implemented to provide 2 MOPP for the heating rod?
