This standard is an important method for determining the content of eight soluble heavy metals in adhesives. It specifies the specific procedures for detecting lead, chromium, cadmium, barium, mercury, arsenic, selenium, and antimony, and provides clear method detection limits. The core of the standard lies in evaluating the specific chemical forms of heavy metals in adhesives, rather than the total amount, as soluble heavy metals generally exhibit higher biological toxicity. When conducting tests according to this standard, the key instrument is the graphite furnace atomic absorption spectrometer, which is used for highly sensitive qualitative and quantitative analysis of samples extracted with specific solutions. This method serves as a foundational technical specification for controlling the environmental and safety performance of adhesives and ensuring compliance with relevant regulatory limits.
