| Report Issued Date | Mar 17, 2026 |
| DUT Notes | During +12V OCP testing, the unit showed high ripple (>200 mV) under both normal and hot conditions. The first sample broke. We stopped the second sample's +12V OCP tests about a minute after the ripple exceeded 200mV to avoid damaging it. As a result, we cannot provide an ATX v3.1 certification for this sample. |

F.1 General Statement
Measurement uncertainty associated with the reported results was evaluated and estimated in accordance with JCGM 100:2008 (Guide to the Expression of Uncertainty in Measurement — GUM) and ISO/IEC 17025:2017, Clauses 7.6 and 7.2.
The uncertainty budget accounts for all significant identified contributors arising from the measurement process, instrumentation, test conditions, and operator interaction.
The reported expanded uncertainty U is obtained by multiplying the combined standard uncertainty uc by a coverage factor k = 2, corresponding to a confidence level of approximately 95 %, assuming a normal probability distribution.
Unless otherwise stated, the reported uncertainty applies only to the specific measurements performed and does not include long-term drift, aging effects, or future environmental changes.
