This standard specifies the types of buffer solutions used for pH value determination, the required reagents, equipment and preparatory steps. It is suitable for buffer solutions used in laboratories under different temperature conditions. The standard lists six different buffer solutions, covering the temperature range from 0 ° C to 95 ° C. The standard emphasizes the purity requirements of the required chemical reagents and requires the use of high-purity water for solution preparation to ensure the accuracy and reliability of the determination results. This standard provides laboratories with scientific methods for preparing buffer solutions.
