Material Characterizations for Compliance with EU Regulations on RoHS

3 - 5 The flowchart is based on the EU administrative test method that was originally proposed by
Material Characterizations for Compliance with EU Regulations on RoHS Non-Destructive Simultaneous Screening & Measurements for the six substances the JBCE (Japan Business Council in Europe) in 2003 to the EU for the public administration of

6 - 9 testing the six substances regulated under RoHS.
Energy Dispersive X-Ray Fluorescence Spectrometer EDX

10 - 11 • Effect of clarifications to applicable exemption status of restricted brominated flame retardants
Wavelength Dispersive X-Ray Fluorescence Spectrometer WDX • Clarification of criteria when evaluating by bromine content in brominated flame retardants
Since RoHS is subject to Article 95 of the EU Treaty, lobbying to harmonize content inspection methods
12 - 16
Optical Emission Spectrometer OES among all EU member countries continues. However, with little progress from the EU itself, the IEC is
considering standardizing inspection methods.
