Foreword
The Standard Appendix A, Appendix B is an informative annex.
This standard is proposed and managed by the National Certification and Accreditation Administration Committee.
This standard by the People's Republic of China Guangdong CIQ is responsible for drafting, Shenzhen People's Republic of China Entry-Exit Inspection and Quarantine
Bureau, Xiamen People's Republic of China participated in the drafting Exit Inspection and Quarantine.
The main drafters of this standard. Liuchong Hua, Zhong Zhiguang, Mu Junze, Zeng Jiaxin Huang Li Na, Zhang Haifeng, Huang, Lee Jun, Xiao Dahui.
This standard is the first release of the entry-exit inspection and quarantine industry standards.
Plastic and its products of lead, mercury, chromium, cadmium,
Barium, arsenic was measured by Inductively Coupled
Plasma atomic emission spectrometry
Warning. Use of this standard should have practical experience in regular laboratory work. This standard does not point out all possible security asked
question. Users have the responsibility to take appropriate safety and health practices and to ensure compliance with the conditions of the relevant provisions of the State.
1 Scope
This standard specifies the inductively coupled plasma atomic and plastic products (excluding plastic polyvinyl fluoride) Lead (Pb) emission spectrometry, mercury
(Hg), chromium (Cr), cadmium (Cd), barium (Ba) and arsenic (As) content approach.
This standard applies to plastics and articles thereof (except plastic polyvinyl fluoride) Lead (Pb), mercury (Hg), chromium (Cr), cadmium (Cd), barium (Ba) and arsenic
(As) measurement.

3 Method summary
A sample was concentrated nitric acid, hydrogen peroxide, a mixed solvent tetrafluoroborate by microwave digestion solution by inductively coupled plasma after digestion
Atomic emission spectrometer to determine the content of each element according to the working curve.
4 Reagents
Unless otherwise indicated in the analysis using only the gifted class pure reagents, test water should be consistent with GB/T 6682 provisions of secondary water requirements.
4.1 nitric acid (ρ = 1.42g/mL).
4.2 nitric acid (5 + 95).
4.3 Hydrogen peroxide (ρ = 1.10g/mL).
4.4 tetrafluoroboric acid solution (40%).
4.5 lead, mercury, chromium, cadmium, barium and arsenic standard stock solution (1000mg/L). according to GB/T 602 formulated or direct purchase of certified reference materials.
4.6 Nitrate - tetrafluoroborate mixed solution. Measure 100mL nitric acid (4.1), and slowly poured into 870mL water and then weighed 30mL tetrafluoroborate
Acid solution (4.4) and mix together to give nitric acid - tetrafluoroborate mixed solution.
4.7 lead, chromium, cadmium, barium and arsenic mixed standard stock solution (100μg/mL). Pipette 10.0mL lead, chromium, cadmium, barium and arsenic solution (4.5)
In 100mL volumetric flask, dilute to the mark with nitric acid (4.2) and mix. This solution 1mL contain lead, chromium, cadmium, barium and arsenic each 100μg.
4.8 mercury standard stock solution (100μg/mL). draw 10.0mL mercury solution (4.5) in 100mL flask, diluted with nitric acid (4.2) to
Volume, and mix. This solution 1mL containing mercury 100μg.
4.9 lead, chromium, cadmium, barium and arsenic series of standard solution. Pipette 0mL, 1.0mL, 2.0mL, 5.0mL, 10.0mL lead, chromium,
