Get the hard facts to successful 62368 compliance from your UL experts
The IEC 62368-1 Knowledge Hub covers an exceptionally wide range of topics, which we believe can be helpful to manufacturers and distributors of A/V & ICT equipment.
This Q&A includes many of the questions we have been asked, with answers from UL experts. Registered users may also submit additional questions related to the 62368: UL has the answer.
Q&A: List of articles with IEC 60950-1
We have power supplies & PDU (EN 60950-1 certified) which are shipped as spares with our system or our customer can buy later '“ since after Dec. 20, 2020 EN 60950-1 will be withdrawn, how will we be able to ship these power supplies/PDUs to Europe?
A PSU certified to 60950-1 passes HIPOT test at 2121 V DC between PRI and earth. When it is used in an end product to be certified to 62368-1, does it need to withstand the end product HIPOT test that could be more than 2121 VDC, e.g., 2500 V DC?
Have any other countries / regions been identified other than the EU that will not accept legacy end products certified to 60950-1 (or 60065) after December 20, 2020?
What kind of ES class can we define for the secondary circuits(SELV) of one AC PSU certified according to 60950-1 previously now need to comply with 62368-1:2014 Ed.2, the AC PSU can meet SELV requirement, but cannot meet ES1 requirement.
According to IEC60950-1, Chapter 5.2 Electric Strength, Table 5B, the test voltage is 1500VAC for a device with basic insulation and 230VAC operating voltage. Where can I find this test voltage for such a device in IEC62368-1?
IEC62368-1 has three methods for determining the electric strength test voltages. Those are explained in sub-clause 5.4.9.1. As stated, the highest value calculated…
Does sub-clause 4.1.1 and its provision for accepting 60065 and 60950-1 compliant AV or ICT components remain in Edition No. 3 of IEC 62368-1?
How much actual new testing will be required to move from product investigations currently to IEC 60950-1 to IEC 62368-1?
Unfortunately, this sort of question cannot be addressed in depth in this sort of forum since the answer is mostly dependent on the specific product type (construction,…
I understand that AV/ICT products with rechargeable batteries have significant changes in requirements associated with 62368-1 compared to 60950-1 or 60065. Can you expand on this?
The answer to this question requires a detailed discussion of Annex M of IEC 62368-1 with your local UL representative, including both its references to component…
Will there be an additional cost for FUS to apply for UL 62368? We are existing UL 60950 customer.
You asked if there will be an additional cost for FUS to apply for UL…
What is the impact on products of touch temperature limits in 62368-1 as compared to touch temperature limits in 60950-1 and 60065 standards?
You asked what the impact is on products of touch temperature limits in 62368-1 as compared to touch temperature limits in 60950-1 and 60065 standards.

Is sub-clause 4.1.1'™s provision to accept 60065 & 60950-1 legacy components in 62368-certified equipment being removed from EN 62368-1:2014?
We have heard sub-clause 4.1.1'™s provision to accept 60065 & 60950-1 legacy components in 62368-certified equipment is being removed from EN 62368-1:2014. Is…
During my transition from IEC 60065 and/or IEC 60950-1 to IEC 62368-1 do all my safety labels need to be changed?
You asked if you need to change your safety labels as you transition to 62368-1.
The answer is not a simple yes/no answer.
Ideally, all…
62368 Clause 5.2.2.5 states that voltage cannot go over 42.4Vpk if less than 3secs. So, does this mean in hiccup mode the output cannot go over 42.4Vpk? Therefore a 48V output will not pass to ES1? This is different to 60950.
It is understood you are asking, 'œWhat are the ES1 voltage limits when a power supply goes into a hiccup mode (repetitive peaks) i.e., pulse off time less than…
How does IEC 62368-1 handle '˜Small Parts'™ in the context of flammability requirements?
As we know, in the context of risk of fire, the use of the term 'œsmall parts' often was the source of some confusion in IEC 60950-1.
For example,…
