NISTís new Integrating Sphere used for accelerated ultraviolet weatherability testing of coatings, plastics, textiles and fiber-reinforced polymeric composites. The sphere was created to implement materials testing planned by the industry/government Coatings Service Life Prediction Consortium. Ned Embree (left), senior technician, and Dr. Joannie Chin, materials research engineer, both of the Building Materials Division of the NISTís Building and Fire Research Laboratory, hold a specimen container up against an Integrating Sphere port. Dr. Chin is one of the inventors of the accelerated ultraviolet weatherability testing device.
