Foreword

The requirements of the Basic Provisions for Standards are written. This standard measurement method is based on domestic and foreign related literature, and has been developed after repeated research, experimentation and verification. This standard has been formulated at the same time Sampling and sample preparation methods. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard was drafted. Xiamen Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China. The main drafters of this standard. Wu Yuhuai, Cai Yizhen. This standard was first published. People's Republic of China entry and exit inspection and quarantine industry standards Copper, lead, mercury and arsenic in Chinese patent medicines exported Test method atomic absorption spectrophotometry  range This standard specifies the sampling, sample preparation and atomic absorption spectrophotometric methods for the determination of copper, lead, mercury and arsenic in Chinese patent medicines for export. This standard is applicable to the test of copper, lead, mercury and arsenic in Chinese traditional medicines such as Liuwei Dihuang Pills and Xinzhi Tablets. The provisions contained in the following standards constitute provisions of this standard by reference in this standard. At the time of publication of this standard, the versions shown are To be effective. All standards will be revised and parties using this standard should explore the possibility of using the latest version of the following standards. Regulation  Definition This standard uses the following definition. Inspection lot. The same production batch number is an inspection lot. Goods with the same production lot number should have the same characteristics, such as product name, packaging, marking, origin, specifications and grade. 抽样 Sampling and sample preparation . Sample size If the total number of boxes (pieces) is less than 100, sample 3 pieces; 100 to 1000 pieces, sampled at 3%; For more than 1000 pieces, the excess is sampled at 1%; Less than 3 pieces, sampled one by one. . Sampling method The number of samples according to 4.1 is randomly selected and opened one by one. Granular, powdered proprietary Chinese medicines can be sampled with a sampler, at each At least 2 to 3 samples of the different parts of the box (piece) are taken. The sampling amount of each box (piece) is generally as follows. Generally, Chinese patent medicines are 10g to 50g; valuable Chinese patent medicines are 2g to 5g. Each inspection lot sample shall be sealed, marked with marks, batches, and sent to the laboratory. . Sample preparation ...
