Can the RoHS2.0 test instrument complete ten items with one instrument? The following by Hong Sheng Xiaobian tell you the answer.
RoHS2.0 test required equipment must be two can be completed, a fluorescence spectroscopy instrument to test the six elements of RoHS1.0, the remaining four are phthalic compounds, at this time need a gas chromatography instrument or liquid chromatography instrument to complete the testing of phthalic compounds. One sentence "rohs2.0 test required equipment, need to be two instruments, a single can not be completed!"
1, the first thing to understand is that the test project of RoHS2.0 is built on the basis of rohs1.0 control, and four new phthalates are added: di-(2-ethylhexyl) phthalate (DEHP), butylbenzyl phthalate (BBP), dibutyl phthalate (DBP), diisobutyl phthalate (DIBP).
2, rohs1.0 control includes six elements: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs), there is a fluorescence spectroscopy instrument to complete the test, the fluorescence spectroscopy instrument test is simple, a few minutes a sample;
3, four phthalic compounds can also be called phthalic divalent esters, you need gas chromatography instruments or liquid chromatography instruments to complete, because the fluorescence spectrometer can only measure elements, can not measure compounds.
