1. Introduction of total lead test


In recent years, in the recall cases of CPSC, lead content exceeded the standard frequently. Lead is widely used in a variety of daily consumer goods, such as toys, children's jewelry, packaging materials, food containers, ceramic products, furniture, stationery, metal accessories and so on, which is closely related to people's life. Excessive lead will have a significant impact on the human body and even the environment, such as the accumulation of high content in children's blood, which will affect children's IQ. In order to ensure human health and reduce the pollution caused by the accumulation of lead in the environment, countries around the world have promulgated corresponding regulations or standards to control the lead content in products at a safe level.


At present, according to the international standard, it is generally believed that the relative safety standard of blood lead should not exceed 10-14 μ g / L. Long term exposure to lead compounds or inhalation of metal lead dust can cause different degrees of "lead poisoning" (the serum lead concentration is more than 40 mg / 100ml) μ g) Excessive inhalation will harm the nervous system, heart and respiratory system, leading to lead poisoning in different degrees. Lead in the human body can combine with a variety of enzymes, thus interfering with various physiological activities of the organism, causing harm to the organs of the whole body. Children are far more likely to have lead poisoning than adults.



2. Test limit of total lead content


1) According to the 2008 consumer product improvement act of CPSIA, ASTM F963 will become a mandatory standard after February 10, 2009, and the lead content limit in lead containing coatings will be reduced to 90ppm (although the requirement has been suspended by CPSC, the manufacturer is still obliged to meet the limit requirement);


2) According to a bill proposed by the Canadian government in June 2009, the limit of lead content in all consumer goods that may come into contact with the mouth (including the accessible parts designed for children under 3 years old) is changed from the current 600 ppm to 90 ppm;


3) According to CPSIA, the total lead content is limited to 600 ppm after February 10, 2009; After August 14, 2009, the total lead limit is 300ppm; After August 14, 2011, the total lead content was limited to 100 ppm.
