The updated standard clarifies some of the problems of the old standard and introduces the requirements of IEC 62368-1.

Manufacturers need to consider whether updated or new standards affect existing product designs and risks, and prepare corresponding documentation and supporting data.

2. Replace the existing requirements of subclause 7.2.3.The use of safety symbols should be based on risk management and usability engineering considerations.If applicable, the risk management documentation and usability engineering documentation shall be updated. If necessary, product nameplates, instruction manuals and other accompanying documents shall be adjusted accordingly and have compliance evidence for usability evaluation.

3. Updated Table 2 (Table 2 – Colours and meanings) according to the requirements in IEC 60601-1-8Provides further clarification between indicator lights and alarm lights.If applicable, check the color of the light and whether it is accompanied by flashing and/or sound.

5. Added Figure 40 ((Figure 40)


Insulation protection according to IEC 60950-1:2005 or IEC 62368-1:2018 can be used as operator protection (MOOP). However, there is no automatic conversion to Patient Protection (MOPP).

The purpose of the newly added process is to assist developers to determine security protection requirements. Although IEC 62368-1 is referenced, it can only supersede some requirements.

The final compliance still has to be assessed according to the original process (Figure 5) and risk management. Among them, special attention needs to be paid to the limiting conditions of the working voltage.

The changes mentioned above mainly consider general medical equipment. For specific medical devices and complete standard requirements, please refer to the complete standard.
