Corresponding range: ML-FDS400 →What this report covers
- Physical source page 3 states that this descriptive verification report must be used together with C-14201-DC197420.
- The website model is a commercial family name; the original laboratory model and tested arrangement remain controlling.
- This is a Chinese GB/T report, not an IEC certificate or a blanket qualification of every offered configuration.
- Pass, inherited pass, document-review pass and N (not applicable or not tested) are kept distinct.
- Report scope has been reviewed against selected identity, change and result pages. A physical-page count alone is not a page-by-page completeness or authenticity audit.
