ASTM D4141-01

Standard Practice for Conducting Black Box and Solar Concentrating Exposures of Coatings

SCOPE
1.1 This practice covers two accelerated outdoor exposure procedures for evaluating the exterior durability of coatings applied to substrates.
1.2 The two procedures are as follows:
1.2.1 Procedure A--Black Box Exposure.
1.2.2 Procedure B-- has been deleted from this practice.
1.2.3 Procedure C--Fresnel Reflector Rack Exposure.
Note 1--Procedure B described a Heated Black Box procedure that is no longer in common use.
1.3 This standard does not cover all the procedures that are available to the user for accelerating the outdoor exposure of coatings. Other procedures have been used in order to provide a particular effect; however, the two procedures described here are widely used.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
