The fluorescent whitening agents (FWAs) used in textiles have different UV absorption properties than those used for plastics and other non-textile materials. Calibration with the AATCC textile standard improves inter-instrument agreement for textile measurements over calibration with the white plaque supplied by the spectrophotometer manufacturer. When retailer, brand, and manufacturer numbers agree, everyone can be more confident in approval decisions!
In this package, you will receive the following materials:
• 1 Textile UV Calibration Specimen (TUVCS) labeled with its CIE-Whiteness value, Specimen ID number, issue date, & expiration date
• 1 copy of AATCC Evaluation Procedure 11: Spectrophotometer UV Energy Calibration Procedure for Optically Brightened Textiles
• 1 Certificate of Traceability
