GB/T 23113 - 2023 focuses on sample preparation for the detection of mercury content in discharge lamps. The standard specifies in detail the method of obtaining representative samples from various types of discharge lamps, covering the dismantling process, mercury collection points, to avoid mercury loss or pollution. Clarify the sample pretreatment steps, such as cleaning, drying and crushing methods, to ensure the accuracy of subsequent testing. Through standardized operation, samples that meet the detection requirements can be prepared to provide a reliable premise for the accurate determination of mercury content in discharge lamps, to help environmental protection departments supervise and the lighting industry optimize products, and reduce the potential harm of mercury to the environment and human body.
