1, RoHS is a mandatory standard formulated by EU legislation, and its full name is Restriction of Hazardous Substances in Electronic and Electrical Equipment. This standard was formally implemented on July 1 2006. It is mainly used to standardize the materials and process standards of electronic and electrical products, making them more conducive to human health and environmental protection.

The purpose of this standard is to eliminate lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers (note: the correct Chinese name of PBDE refers to polybrominated diphenyl ethers, but the polybrominated diphenyl ethers are incorrect) in electronic and electrical products, and emphasize that the cadmium content should not exceed 0.0 1%.

2. Hedge fund refers to a financial fund that combines financial derivatives such as financial futures and financial options with financial institutions, takes high-risk speculation as a means, and aims at profit.

Extended data:

If the product fails to pass RoHS certification, it will cause immeasurable losses to the manufacturer. At that time, the products will be ignored and the market will be gone. If the product is lucky enough to enter the other market, once it is found out, it will encounter high fines and even criminal detention, which may lead to the closure of the whole enterprise.

Hedge funds use various trading methods to hedge, transpose, hedge and hedge to make huge profits. These concepts have gone beyond the traditional operation scope of preventing risks and ensuring benefits. In addition, the legal threshold for launching and establishing hedge funds is much lower than that of mutual funds, which further increases their risks.
