适用范围: 4.1x00a0;Color measurement quantifies the coating color for glass and is often related to coating thickness and composition as well as tinting used in the substrate glass. The user of this document defines an acceptable range of color appropriate for the end use. Typical quality concerns for the reflected color measurement of coated glass products are an indication of consistency in the coating process and verification of lot-to-lot color consistency for end-user acceptance.

4.2x00a0;If the reflected color of a glass product is consistent from lot-to-lot and within agreed supplier-buyer acceptance criteria, that product color is expected to be consistent and acceptable for end-use.

1.1x00a0;This practice provides guidelines for the instrumental reflectance measurement of the color of flat, coated and uncoated glass. See Terminology E284.

1.2x00a0;The practice specifically excludes fluorescent and iridescent samples.

1.3x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4x00a0;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.
