Are you ready for IEC 62368-1?

With the switch to UL 62368-1, Astrodyne is helping customers adapt the way they seek certification for their products.

Customers in the UK who request an EN approval, TUV mark or CE mark will benefit from Astrodyne’s thorough understanding and application of the new safety standards. 

In a bid to help information technology equipment (ITE) and audio/video equipment (AV) builders keep up to speed with the latest product safety standards, Astrodyne TDI have posted a comprehensive article which focuses on the changes manufacturers should be aware of.

Seen as a substantial change, the new IEC 62368-1 compliance standards replace standards IEC 60950‑1 and IEC 60065. As the boundaries between ITE and AV equipment become increasingly merged, the new, single set of standards will cover both the ITE and AV industries.

With the new compliance standards comes revised product testing and certification requirements. Manufacturers needing to understand the new requirements and how to implement them will benefit from Astrodyne’s article, which can be viewed here: An introduction to IEC 62368-1 standards and compliance

An overview of changes

IEC 62368-1 is not merely a merger of the two pre-existing standards — it is based on an entirely different set of engineering terms and principles.

  • To make the new standards easier to apply to new technologies without amendments, IEC 62368-1 is not a product-dependent standard

  • It focuses on the energy sources inside a product and how they are managed

  • Significant change from incident-based regulation to hazard-based safety engineering

  • IEC 62368‑1 places all tests into Annexes instead of in the body of the standard. This was meant to facilitate easier edits and updates in the future
New terminology is used throughout the new standards. It is therefore imperative for manufacturers to relearn the application and intent of each word and phrase. As an example, the phrase" "abnormal condition" has been changed, so it excludes non-normal conditions caused by a component or part failure.

Publication of the new regulations means that product safety engineers and manufacturers should consider what products fall within its scope. Existing products that meet IEC 60950-1 or 60065 standards may need to be re-investigated to ensure they meet the new IEC 62368-1 compliance standards.

All equipment currently subject to IEC 60950-1 and 60065 safety standards is covered under the new IEC 62368-1, including products, components and associated subsystems. However, there are other products currently outside of these categories that will also be subject to the new regulation.

The IEC 62368-1 2nd edition defines the basic list (certainly not exhaustive) of covered products as follows:

  • Network and computer products, including servers, routers, PCs, notebook computers, laptop computers, tablets and all associated power supplies
  • Consumer electronics such as digital cameras, personal music players and hi-fi systems
  • Computer monitors, TVs, projector systems and other types of displays
  • All phones, communication devices and other network infrastructure equipment
  • Office appliances, printers, copiers and shredders.

ICT and AV equipment that doesn’t fall into one of the categories above will not necessarily be exempt from IEC 62368-1 safety standards. However, some products that are not specified by this regulation include the following:

  • Any equipment designed to be used in wet areas or outdoor installations
  • General manufacturing processes do not matter to the regulation. Only safety testing is of concern
  • Any storage, transportation or disposal of applicable equipment is not regulated under this standard
  • Any products that are forcibly combusted and any injuries caused by the resulting gasses are not covered by the safety requirements of this standard
  • Similarly, injuries caused by flammable liquids, chemicals, or electrostatic discharge events are also not covered under this standard.

Affect on power supplies

As IEC 62368-1 also applies to associated components and subsystems, it means that power supplies also fall within its scope. This includes chassis-mount, external power supplies and adapters. For manufacturers and OEMs, very little will change from a design standpoint. Astrodyne outline the primary differences in their article
