What are the contents of RoHS testing? Why RoHS test report?

A, we need to know the reasons for the introduction of RoHS certification: \x0d\ The first time it was noted that electrical and electronic equipment contains heavy metals harmful to human health is the Netherlands in 2000 in a number of marketed game consoles in the cable found in cadmium. In fact, the solder used in large quantities in the production of electrical and electronic products, and the ink used in the printing of packaging boxes contain lead and other harmful heavy metals. \x0d\ 2, ROHS testing standard is 2011/65/EU, then the European RoHS 2011/65/EU requires the testing of six items, which are: \x0d\ 1, Lead (Pb) \x0d\ 2, Cadmium (Cd) \x0d\ 3, Mercury (Hg) \x0d\ 4, Hexavalent Chromium (Cr6+) \x0d\ 5, Polybrominated Biphenyls (PBBs) \x0d\ 6, polybrominated diphenyl ethers (PBDEs)\x0d\ The content of the six hazardous substances in the above homogeneous substances must not exceed the limit values, of which cadmium is 0.01% and the rest is 0.1%. We live in the common white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc.; black appliances, such as audio, video products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc.; power tools, electric and electronic toys, medical and electrical equipment, etc., in the production process and raw materials may contain these six hazardous substances, so there is no testing and certification. After the test qualified case, want to enter the EU market is not possible, because RoHS is a mandatory standard developed by the EU legislation. \x0d\\\x0d\ 3, June 4, 2015 Update: The EU issued RoHS 2.0 Revised Directive formally added four kinds of toxic and hazardous substances (DEHP, BBP, DBP, DIBP) to the scope of RoHS 2.0 control, plus the addition of the new four kinds of restrictions on the toxic and hazardous substances *** there are 10 kinds of, as follows: \x0d\ 1, lead (Pb) \x0d\ 2 , Cadmium (Cd)\x0d\ 3, Mercury (Hg)\x0d\ 4, Hexavalent Chromium (Cr6+)\x0d\ 5, Polybrominated Biphenyls (PBBs)\x0d\ 6, Polybrominated Diphenyl Ethers (PBDEs)\x0d\ 7, Diisobutyl Phthalate (DIBP)\x0d\ 8, Phthalic Acid (2-Ethylhexyl Ester) (DEHP)\x0d\ 9, Dibutyl phthalate (DBP)\x0d\ 10, Benzyl butyl phthalate (BBP)
