Specifies requirements, in addition to those AS/NZS 3000 for electrical installations in hospitals and medical and dental practices where electromedical procedures are performed on a regular basis. In addition, specifies requirements for cardiac-protected and body-protected electrical areas. Included in the appendices are typical forms for commissioning tests for patient areas, methods of measuring magnetic fields and resistance calculations in equipotential areas.

This Standard sets out requirements for electrical installations in PATIENT AREAS of hospitals, medical and dental practices, and dialyzing locations.Areas other than PATIENT AREAS are not covered by this Standard, but are covered by the relevantrequirements of AS/NZS 3000.NOTES –(1)Attention is drawn to AS/NZS 2500,which outlines the procedure for determining whereCARDIAC-PROTECTED ELECTRICAL AREAS are required. These decisions are made by the governingbody or proprietor of the health care facility, based on the classification of the medicalprocedures undertaken in each area and the protection against electric shock provided inthe MEDICAL ELECTRICAL EQUIPMENT available for these procedures.(2)A rationale for the requirements of this Standard is given in Appendix A.(3)Requirements for mobile trolleys supporting electrical equipment are given inAS/NZS 3200.1.1 and AS/NZS 4510.(4)Requirements for emergency lighting are given in AS/NZS 2293.1.(5)Requirements for emergency power systems in hospitals are given in AS/NZS 3009.
