Get the hard facts to a successful transition – from your UL experts
The IEC 62368-1 Toolkit covers an exceptionally wide range of topics, which we believe can be helpful to manufacturers and distributors of A/V & ICT equipment as you plan your transition.
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 transition: UL has the answer.
Q&A: You ask, we answer
I have a question on a GDT connected in series with an MOV in Type A pluggable equipment and how this construction impacts application of 5.5.7, G.8.1 in the context of post production Hi-Pot testing at 1.5 kv.
Is it possible to use some of the latest provisions in Ed. No. 3 IEC 62368-1 for Ed. No. 2 IEC 62368-based certifications of AV/ICT equipment while industry waits for Ed. No. 3-based versions of EN, CSA, UL and other national standards?
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 18.104.22.168. As stated, the highest value calculated…
If we have a product that its output 3.3V SELV, 16 W (more than 15W) or PS2 energy that meets Table Q.1 requirements. Does the power need to be contained?
When can my company begin submitting AV & ICT equipment and components for product investigation and certification to Edition No. 3 of IEC 62368-1?
When will the rationale document, IEC TR 62368-2, be updated to reflect 62368-1 Edition No. 3 content?
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?
What are the key differences between the existing Edition No. 2 of IEC 62368-1 and the recently published Edition No. 3?
Would an LAN output connector of a laptop computer intended for connection to a router within the same building, be defined as a paired conductor external circuit as per ID 1 of table 14 within EN 62368-1.
Does the point B.2.6.2 in EN 62368 force to perform temperature measurement for Cause 6 at real Trma (manufactures max allowed ambient temperature of the DUT)?
Why evaluate to Edition No. 2 of IEC 62368-1 now, when we will have to test to Edition No. 3 by 2020?
Evaluations to 3rdEdition will not universally be required in 2020. Edition No. 3 of IEC 62368-1 will not become mandatory until it is adopted in Europe,…
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,…
Given that the 2nd edition is more onerous, what is the likelihood of an agency such as UL allowing a 3rd edition relaxation in their 2nd edition certification?
It’s an oversimplification to state that Ed 2 is more onerous than Ed 3. A better way to view it is that Ed 3 has incorporated some refinements into it that…
For IEC 62368-1’s Annex G.9 on IC current limiters, one of the stated conditions is that the IC is supplied by a source whose output does not exceed 250VA. Can you provide some background on this change?
Annex G.9 is being overhauled in Edition No. 3 of IEC 62368-1, including a new test program replacing the existing three test programs. A 250VA power source…
Currently, there is no Mexican National Standard or adoption of IEC 62368-1, 2ndEd.
