This standard provides two methods for determining the color of natural raw rubber. Method A involves visual color comparison using standard color glass plates, while Method B utilizes a color spectrophotometer for instrumental determination. In case of disputes over test results, Method B shall be the preferred method. To ensure the accuracy of color determination, samples must be mixed using a laboratory mill and molded into test pieces of specified thickness under standard conditions using specific molds and a flat-plate vulcanizing press. This standard is used to evaluate the color quality of natural raw rubber.
