Note:
Remark:
-MDL = Method Detection Limit
-N. D. = Not Detected (<MDL)
-mg/ kg = ppm = parts per million
-BL = Under the XRF screening limit
—X= The symbol “X” marks the region where further investigation is necessary.
Test Method
A. Screening test by XRF spectroscopy
XRF screening limits in mg/ kg for regulated elements according to IEC 62321-3-1:2013 Ed.1.0
1.The screening results are only used for reference.
2.When conducting the test for PBBs&PBDEs, XRF was introduced to screen Br
Exclusively; When conducting the test for Hexavalent Chromium, XRF was
introduced to screen Chromium exclusively.

Note: -BL = Under the XRF screening limit
-OL = Further chemical test will be conducted while result is above the screening limit.
—X= The symbol “X” marks the region where further investigation is necessary.
