Homogeneous materials
WebRemember: RoHS applies at the level of homogeneous materials, such as materials of uniform composition. If your product contains 100 different components, then there may be 500 homogeneous materials to test. If you want to verify the presence of the 10 RoHS substances, then it is 5 000 tests that the lab will do in total.
