China RoHS
“China RoHS” is the term used by industry generally to describe legislation
implemented by the Ministry of Information Industry (MII) in the People's Republic of
China for the control of pollution by electronic information products (EIP). The official
title of the China RoHS regulation is “Management Methods for Controlling Pollution by
Electronic Information Products.”
China RoHS bans the same substances and has the same limits as EU RoHS.
However, the China RoHS regulation requires specific product marking and a self-
declaration of the controlled substances contained in each product.
Intel Desktop Board DH57JG is a China RoHS-compliant product.
The required China RoHS mark indicates the product’s Environmental Friendly Usage
Period (EFUP). The EFUP is defined as the number of years for which listed controlled
substances will not leak or chemically deteriorate while in the product. The EFUP for
Intel Desktop Boards has been determined to be 10 years.
The EFUP for Intel Desktop Board DH57JG is shown in Table 21.
