Technical terms and definitions The following technical terms and definitions are applicable to this Standard. 3.1 Electroplating It means the process to deposit one layer of

38、 uniform, dense and well-coherent metal or alloy on the surface of parts by electrolytic method, including the treatments (deoiling and derusting) before plating, plating of metallic layer and treatments after plating (passivation and dehydrogenation). 3.2 Existing enterprises It means the plating e

39、nterprises and plating facilities that have been built and put into production or the documents for evaluation of environmental impact have been approve 4before the implementation date of this Standard. 3.3 Newly-built enterprises It means the construction projects of newly-built, reconstructed or e

40、xpanded plating facilities that the documents for evaluation of environmental impact have been approve from the implementation date of this Standard. 3.4 Zinking It means the process to deposit the plating coat of metallic zinc on the surface of parts by dipping the parts into zinc-plating solution

41、as cathode and using zinc plate as anode while switching on DC power supply. 3.5 Chromium plating It means the process to deposit the plating coat of metallic chrome on the surface of parts by dipping the parts into chrome- plating solution as cathode and using lead alloy as anode while switching on

42、 DC power supply. 3.6 Nickel plating It means the process to deposit the plating coat of metallic nickel on the surface of parts by dipping the parts into nickel salt plating solution as cathode and using metallic nickel plate as anode while switching on DC power supply. 3.7 Copper plating It means
