Medical IT systems should be commissioned to BS 7671 Section 710 and the maker's recommendations: correct and labelled protective devices; local and remote alarms demonstrated; circuit insulation resistances measured and compared with the IMD reading, with the IMD alarm proven by reducing insulation; transformer leakage current with secondary open below 0.5 mA; changeover at the common coupling point proven no-break, within 0.5 s or within 15 s as intended; supplementary bonding measured and recorded including extraneous metalwork and outlets relative to the EBB.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
