IEC 62368-1 introduces itself

The IEC 62368-1 standard is used to implement the Low Voltage Directive and is applied to a wide range of products in the IT as well as the audio and video industry.

How does the EN/IEC 62368-1 change over time?

The standards landscape is constantly in motion. Constant product developments bring with them ever new requirements for product safety. The current situation is described below.

Global market access

The IEC 62368-1 standard is widely recognized in various world markets due to its good harmonization and wide scope. How to find the lowest hurdles for diverse markets, you will experience with us. The VDE has an established network and opens doors for you.

What rules apply in Europe's trade zones?

The different trade zones also have different access regulations. Generally, as a manufacturer, you have to make a declaration that assesses the technical risks of your product. The CE marking obligation also applies in the EFTA states. Switzerland is an exception here. Here there is a separate free trade agreement with the EU.

Which edition do I use for my CE declaration?

The CE declaration of a manufacturer is the entrance ticket to the European market. EN IEC 62368-1:2014 (2nd edition) is currently the appropriate standard. This is listed in the "European Official Journal" of the EU and thus has the effect of presumption for compliance with the Low Voltage Directive. The VDE provides support here with technical tests to ensure product safety.

In addition, a large number of European countries are members of CENELEC. Thus, a common EN standard applies, the EN IEC 62368-1:2020 +A11:2020.

Note: By 06.07.2024 the DOW (date of withdraw) of EN IEC 62368-1:2014 is set, after that the effect of presumption is no longer valid. Currently, due to CENELEC membership, a delta analysis to EN IEC 62368-1:2020+A11 2020 (3rd edition) is recommended. This recommendation will be adapted when a 4th edition of EN IEC 62368-1 is available. It is expected that the 4th edition will be listed in the "European Official Journal" of the EU.

Which output do I use for my UKCA declaration?

Even if there is a differentiation here due to the different formal framework, the UKCA declaration is strongly based on the CE declaration. With regard to the standard for technical assessment, there is no difference. As of August 1, 2023, the British government has additionally declared that the CE marking will continue to be recognized in the British market for an unlimited period of time.

What exactly does the CB process do?

With a CB certificate for your product, you can ensure market entry in the majority of markets worldwide. The standard used for this purpose is IEC 62368-1. However, the locally recognized editions may differ. Country-specific requirements such as the conversion of a CB certificate into a locally recognized certification mark or regular production site monitoring must be taken into account. Here, VDE has both the network and the necessary experience to best support your project.

Technical modifications of IEC 62368-1:2023 (4th edition)

Since 29.05.2023 the 4th edition of IEC 62368-1 is published. In the course of this, there are some technical new requirements. The main sections and their influences compared to the 3rd edition of IEC 62368-1 are listed below. So, there are many more minor adjustments, from editorial to technical. To give you a quick access to this knowledge, VDE offers you everything from consulting contingents to training.

Clause 4.1.1 - Application of requirements and acceptance of materials, components and  subassemblies 

Previously, critical components certified to IEC 60065 or IEC 60950 were recognized as technically acceptable components within a product. This section has been deleted in the 4th edition, which is why only components certified in accordance with IEC 62368-1 are now approved as an alternative.

Clause 4.1.8 - Liquids, refrigerants and liquid‐filled components LFCs

The field of application has been adapted here. Liquid-filled components or assemblies" are now evaluated in a differentiated manner. There are now "modular LFC" as well as "self-contained LFC". Most components and assemblies are assessed as described in G.15. There are some exceptions with small amounts of liquid, e.g. LCD displays, electrolytic capacitors. The exception for components containing more than 1 l of liquid has been removed.

Clause - Determining external circuit transient voltages (Table 13) 

A revised listing of cable types and additionally applicable conditions, designates the transient voltages to be evaluated. There is more differentiation in the cable types than before. This may result in significant changes in the design of the products.

Clause Capacitor discharge after disconnection 

If a capacitor voltage becomes touchable by disconnecting a connector,a distinction is now made between equipment with "type B" plug connection and "other" plug connectors.

Clause 9.3.1 -  Touch temperature limits - Requirements, including Table 37, Touch temperature limits for accessible parts 

This section now also specifies limits for body-worn products with possible direct skin contact.

More clauses under change (list not exhaustive)...

4.1.3 - Equipment design and construction - Safeguard robustness – General - Determining DC mains transient voltages - Separation between external circuits and earth – General - Colour of insulation - Control of fire spread in PS2 circuits – General - Top openings and top opening properties - Bottom openings and bottom opening properties 
B.1.6 - Specific output conditions 
B.2.4 - Normal operating voltages 
B.2.5 - Input test 
B.3.5 - Maximum load at output terminals 
F.2.2. - Graphical symbols 
G.3.5.1 - Safeguard components not mentioned in G.3.1 to G.3.4 – Requirements 
G.7.3.1 - Cord anchorages and strain relief – General 
G.16.2 - IC that includes a capacitor discharge function (ICX) – Tests
