DL/T 430-1992 in English

The industry standard DL/T 430-1992, titled "Determination of Trace Copper in Oil by Zinc Reagent Spectrophotometry," was issued on August 29, 1992, and came into effect on March 1, 1993. This standard specifies a method for determining the trace amounts of copper in oil using the zinc reagent spectrophotometric technique. The method is particularly useful for monitoring the quality of oil in power systems, where the presence of copper can indicate potential issues such as corrosion or contamination.

The procedure involves the reaction of copper ions with a zinc reagent to form a colored complex, which is then measured spectrophotometrically at a specific wavelength. The intensity of the color is proportional to the concentration of copper in the sample, allowing for precise quantification. This method is known for its sensitivity, accuracy, and reliability, making it a preferred choice for laboratories and industries involved in power generation and transmission.

By adhering to this standard, organizations can ensure the integrity and performance of their oil systems, thereby maintaining the efficiency and safety of power equipment. The standard is an essential tool for quality control and preventive maintenance in the energy and power sector.
