Under Glass and Black Box Under Glass Exposures

Black Box under Glass
  • Provides exposure to natural sunlight through glass
  • Determines colorfastness/durability characteristics of materials such as: drapes, carpeting, upholstery, and automotive interior materials
  • Specimens ary typically placed behind 3 mm thick, single-strength window glass
  • Single-strength window glass absorbs radiation below 310 nm and transmits 77% of UV radiation and 85% of visible light
  • Additional tempered, tinted or laminated glass available to match end-use application

Under glass exposures meet the following standards: 

  •  AATCC TM 16 C
  • ASTM G24 method A
  • Ford FLTM B1 160-01
