Saybolt Color is a color evaluation method widely used in liquid products such as petroleum and chemicals. Color changes of products can be accurately evaluated by this method. The test method of Saybolt Color, the requirements of instrumentation and equipment, sample preparation and test steps are described in detail in the standard. This standard helps to ensure the uniformity and conformity of Color in the production process of chemical products, especially in the quality control of liquid products. By adopting this standard, manufacturers can be provided with a reliable Color Assessment tool to ensure that the product meets the expected visual effects and market standards.
