Foreword
In order to implement the “Environmental Protection Law of the People's
Republic of China”, to reduce the impact of coatings on the environment and
human health during production and use, and to protect the environment, this
Standard has been formulated.
This Standard proposes the limit requirements for harmful substances in water
based coatings.
This Standard has revised “Technical requirement for environmental labeling
products - Water based coatings” (HJ/T 201-2005). The main changes are as
follows:
- ADJUST the scope of the standard;
- ADJUST the requirements for substances that cannot be artificially added;
- ADD the limit requirements for glycol ethers and esters;
- IMPROVE the limit requirements for volatile organic compounds;
- IMPROVE the limit requirements for the total amount of benzene, toluene,
xylene and ethylbenzene.
This Standard applies to China’s environmental labeling product certification.
This Standard was formulated by Department of Science and Technology
Standards of the Ministry of Environmental Protection.
Main drafting organization of this Standard: Environmental Development
Center of the Ministry of Environmental Protection.
This standard was approved by the Ministry of Environmental Protection on
March 31, 2014.
This Standard was implemented from July 1, 2014.
This standard is explained by the Ministry of Environmental Protection.
The previous released versions replaced by this Standard are as follows:
- HJ/T 201-2005, HBC 12-2002, HJBZ 4-1999, HJBZ 4-1994.
