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 a color specification with an associated tolerance before the transaction. This guide discusses the concept and details the ASTM standards to be used in the process.
1.1 This guide leads the user through the process for setting a color tolerance for a product or material. It points to the appropriate ASTM standards that affect each step of the process. It includes the discussion points on which the two parties must agree and provides caveats for various options selected.
1.2 This guide does not suggest numerical values for tolerances. These values must be agreed upon by the two 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 and health practices and determine the applicability of regulatory limitations prior to use.
