3M publishes full data for every automotive series, and CR BLK 15 is gone
Every 3M family now shows its test basis. The current Crystalline sheet's darkest CR BLK shade is 30.
- The change
- Logged here
Every current 3M automotive series has a public technical data sheet with tables on 6 mm clear glass and on 73% automotive glass, measured to ANSI/NFRC 200 with IRER over 780–2500 nm. Every 3M family rates as fully published.
3M's current Crystalline sheet (Rev F, August 2025) doesn't list a CR BLK 15 shade. CR BLK runs from 30 to 80 on the sheet, and its best heat number is 59% TSER.
What we updated on Mr. Window Tint
- CR BLK's shade list and heat range now follow the current sheet (32–59% TSER). The database had carried a CR BLK 15 shade from older material.
