The stakeholder asked if it was correct to assume that theYes. This is specified in section 6.5 of the Test Method.
correct test method for testing Short Idle was a combination ofIEC 62623, Ed.1.0 Clause 5.3.5 and Test Method sections 5.1
and 5.2.
Yes. This is the correct assumption.
The stakeholder requested verification if it was correct toassume that the test method should be read as follows:– switch on the EUT;
– once logged in with the operating system fully loaded andready, close any open windows- follow sections 5.1 and 5.2A) to H) of the test method– once the EUT has entered short idle mode, reset the meter (ifnecessary) and begin
accumulating true power values at an interval of one or more
readings per second;– accumulate power values for 5 min and record the average(arithmetic mean) value
observed during that 5 min period as PSHORT_IDLE
This also means that instead of using “…the standard
operational desktop background screen or equivalent readyscreen…” per CL .5.3.5 of to IEC 62623, Ed.1.0, that section
5.2 of the test method is followed which means using theENERGY STAR test image per section 5.2 F).
The stakeholder commented that the reference to IEC 60107 Displays and TVs reference IEC 62087, which includes thedoes not state how to make a simple luminance measurement three-bar video signal. However, the full video content is notin one specific clause of the standard. Stakeholder suggests

that it would be better to just state exactly how the luminance IEC in 5.2B, but for clarity will add in the section number in IEC

will remove the reference to IEC in 5.2D.
The stakeholder questioned whether section 5.2 would need to DOE believes it is possible that some products may leave thebe applied for all of Section 6 tests in the Test Method

The stakeholder commented that if section 5.2 must be applied DOE agrees and will move the 'Off Mode Test' to the last test
