The customer used a 2018 UL 60950-1 report to respond to a new order in 2024.
UL 60950-1 has been withdrawn, and the customer's compliance department requires a UL 62368-1 report, so the entire shipment was put on hold and not accepted.
Conduct a standard gap assessment: differences between 62368-1 and 60950-1 in energy source classification, fire enclosure, and temperature rise criteria; supplement ES1/ES2/PS1/PS2 energy source determination and fire enclosure assessment; retest key items and issue a UL 62368-1 report; simultaneously update the standard references on the nameplate and in the instruction manual.
Complete the standard upgrade in 3 weeks and release the goods.
Standard generation changes are more fatal than "expired reports," and a standard version monitoring mechanism needs to be established. UL 60950-1 has been replaced by UL 62368-1, and new projects should no longer reference it. Reviews by customer compliance departments are often stricter than regulatory reviews, so preparations should be made according to their checklist.
Reversing that order usually costs an extra round of sample and an extra round of testing.
