Currently, the EU is harmful substances based on the requirements of homogeneous material, a lot of people testing security regulations do for a long time. always considered that the testing should be targeted at the finished product, but in doing so ROHS aspects and safety regulations, RoHS do is kind of material analysis, all finished our side to get it. We still take it for the separation, separation to what extent? as separation of homogeneous material level, What kind of material called material mean?The original definition of the EU refers to the physical method can no longer split up the extent, as homogeneous materials, For instance, a power cable, power lines above some ink, if the tests done speaking, We must take Ink sufficient quantities to test, then this is a very difficult task, In this way did not use physical methods it split circumstances, We will Ink Paper and plastic components as a materials testing done together, speaking for the majority of products, If all in accordance with the detection of homogeneous material costs may be very high, except in small electrical appliances enterprises, Foreign buyers in the strong request of the need to provide product report, which is usually finished speaking we do not propose to do. Otherwise enterprises test cost pressure, We can assume that a television will be in accordance with the EU's definition of homogeneous material for the resolution, there may be thousands of homogeneous material, the specific approach or cost-sharing should test of the whole supply chain, levels from the respective vendors to conduct tests in accordance with the EU requirements assigned to do the heterogeneous material. most famous enterprises have the same demands.
