3、 Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 “C and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Procedure Method A - Fade-ometer Exp

4、osure Test (ASTM D 1682, Methods 2C and 2R) 1. Measure and cut two samples 120 x 280 mm, one WalesWarp direction and the other CoursesWeft direction. These are for exposure in the Fade-ometer. Additional specimens, at least two from each direction, shall be prepared according to ASTM D 1682, Method

5、2R or 2C, whichever is applicable, for determining original tensile strength values. 2. Clamp each end of the 120 x 280 mm samples to the revolving frame of thefade-Ometer ensuring that they are in a vertical position and that the surface after fitting is even, .e. not wrinkled.

Expose the samples in the Fade-ometer for 200 standard fade hours under the operating conditions described in FLTM EU-BN 001-01. 4. After exposure, prepare two specimens from each of the aged samples in the same way as for the or

Prior to performing the tensile tests (original and after exposure) ensure that the specimens have been conditioned as required in the material specification for 24 hours. 6. Measure the tensile strength o
