Introduction to "GB/T 28209-2023 Borosilicate Glass Chemical Analysis Methods"
GB/T 28209-2023 is a Chinese national standard that provides comprehensive chemical analysis methods for borosilicate glass. Borosilicate glass is a type of glass that contains significant amounts of boron and silica, making it highly resistant to thermal shock and chemical corrosion. It is widely used in various industries, such as laboratory glassware, pharmaceutical packaging, and cookware.
This standard aims to establish a standardized and systematic approach for the chemical analysis of borosilicate glass. It covers various analytical techniques, including atomic absorption spectrometry, inductively coupled plasma atomic emission spectrometry, X-ray fluorescence spectrometry, and other methods. These methods enable accurate determination of the elemental composition of borosilicate glass, allowing for quality control, product development, and compliance with regulatory requirements.
The chemical analysis methods outlined in this standard are designed to be practical and reliable, ensuring consistent and accurate results. They provide step-by-step procedures for sample preparation, instrument calibration, and measurement techniques. Additionally, the standard includes guidelines for data interpretation and reporting, facilitating the comparison and exchange of analytical results among different laboratories.
GB/T 28209-2023 is essential for manufacturers, testing laboratories, and regulatory authorities involved in the production and quality control of borosilicate glass. It serves as a valuable reference for ensuring the safety, performance, and compliance of borosilicate glass products in various applications.
