Some years ago,the world safety standard bureaus are dedicated to merge information technology&communication technology(ICT) safety standard and Audio&Vedio(AV) appliances into one new safety standard.

From the end of 2020,the new standard has been adopted to ICT&AV products,that is 62368-1.It will be instead of old 60950 standard for ICT products and 60065 standard for AV products.

In different countries and areas,62368-1 is named with different prefix in different areas,like IEC62368-1 for international CB group countries,EN62368-1 for European countries,UL62368-1 for USA,CSA62368-1 for Canada,AS/NZS 62368-1 for Australia&New Zealand etc.

Below we only take IEC62368 standard out for detailed explanation.

It is crucial to understand that IEC 62368-1 is a new type of standard:

  • new options are allowed for product evaluation, and
  • some older definitions and requirements have been changed or removed.

From the beginning, the technical committee meant for IEC 62368-1 to strike a balance. It was intended to:

  • be more performance oriented, while still allowing for known constructions if they have previously been proven safe (for example, in IEC 60065 and/or IEC 60950-1).
  • be technology independent (within reason), and allow for more design freedom.
  • be applicable to a wider range of (known) electronic products, yet still allow easier introduction of new technology to the global marketplace.

The end goal is the design and manufacture of safe products. Because it is to be so widely utilized, the new standard needs to be stable, understandable and user friendly. The new standard is hazard- and performance based, which places more emphasis on evaluating a product for safety during the design stage. There are three significant changes from prior types of standards.

Energy Hazard Limits

Previously, a device was evaluated with regards to how likely a person was to get an electrical shock injury, generally by bridging two ‘live’ operating parts. After considerable study by the Technical Committee, the energy hazard requirement has been removed from IEC 62368-1.

Mechanical Hazards

Hazardous moving parts can now be more easily defined by three levels of hazard:

  • MS1 is a mechanical hazard that does not cause pain or injury.
  • MS2 is a mechanical hazard that does not cause injury but may be painful, (think of pinch points or sharp edges) and
  • MS3 is a mechanical hazard that can cause injury, e.g. it requires medical attention.

Components

In order to smooth the transition between the new standard and the legacy standards, components and subassemblies that comply with IEC 60950-1 or IEC 60065 are accepted without further investigation. This will apply only during this transition, and will be phased out in the future.

For other prefix 62368-1 standards,only country plug and voltage difference,the other aspects are almost the same.
62368-1 standard is not only applicable to ITC&AV products,but also to their electrical facilities like power supplies,ShenZhen Top Power Co Ltd power supplies have been upgrade to 62368-1 standard can can be sold with you ICT&AV products to the worldwide countries.
