Introduction

Safety standards for medical electrical equipment, also known as the 9706 series of standards, consist of general standards, collateral standards, specific standards, guidelines and interpretations.

---General standard. The safety standard that medical electrical equipment should be generally applicable, that is, the equipment that meets the definition of medical electrical equipment should meet this

Basic standard requirements.

--- Parallel standards. safety standards that should be generally applicable to medical electrical equipment, but in most cases are limited to certain specific functions or special

It is only the equipment that needs to meet the requirements of such standards.

---Special standards. Safety standards applicable to a certain type of medical electrical equipment, and not all medical electrical equipment have specific standards
