A Index

Applies to the safety of MEDICAL ELECTRICAL EQUIPMENT. Although primarily concerned with safety, this standard contains some requirements regarding operation where it is connected with safety. Excludes SAFETY HAZARDS resulting from the intended physiological function of EQUIPMENT. Appendices are only mandatory when made so by an explicit statement in the main test. Includes sections on environmental conditions, protection against electric shock, mechanical hazards, radiation, ignition of flammable anaesthetic mixtures, excess temperatures and other safety hazards, accuracy of operating data and protection against hazardous output, abnormal operation and fault conditions, environmental tests and constructional requirements.
