AATCC TM148-2014(2015)e3, Light Blocking Effect of Textiles and Related Materials: Photodetector Method

 

Developed in 1976 by AATCC Committee RA36; reaffirmed 1979, 1984, 1989; editorially revised 1983, 1984, 1985, 1986, 2016, 2019. Discontinued 1994; Reactivated and revised 2014 (with new title); reaffirmed and editorially revised 2015.

 

Foreword

 

AATCC TM148-1989, Light Blocking Effect of Curtain Materials, was discontinued in 1994. During the time of its discontinuance, the need for a method to measure this property continued. The method has now been rewritten and retitled for reactivation, in parallel with an alternative method using a standard laboratory sphere spectrophotometer used in transmission mode (see AATCC TM203, Test Method for Light Blocking Effect of Textiles: Spectrophotometric). The two methods are not equivalent.

 

1. Purpose and Scope

 

1.1 This test method measures the light blocking properties of textile and related materials using a photometer.

1.2 This method is applicable to all types of fabrics, including coated textiles and other textile-based constructions.
