Significance and Use 5.1 The rejection of materials due to color is a common and expensive occurrence, and it is useful for a customer and producer to set color specifications with an associated tolerance before the transaction. This guide discusses the concept and details the ASTM standards to be used in the process.Scope 1.1 This guide leads the user through a process for establishing color specifications, including the target color and allowable tolerances. It refers to the appropriate ASTM standards that more thoroughly describe each step of the process beginning with expectations, encompassing caveats within the process and finally concluding with reporting. 1.2 This guide does not suggest numerical values for tolerances. These values must be agreed upon by the parties involved. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
