4. SPECIFICATION:	To provide an effective accelerated indoor simulation of long-term outdoor short-wavelength UV exposure (295 -360 nm) using a Fluorescent UV accelerated weathering device operated as per:
	ASTM G53-96¹, Standard Practice for Operating Light-and Water -Exposure Apparatus (Fluorescent UV-Condensation Type) for Exposure of Nonmetalic Materials" #of test samples: 5 Duration: 1000 hrs Exposure: UVA-340 lamps Cycle 1: 8 hrs UV at 60°C black panel temperature, followed by 4 hrs condensation at 40°C
	Evaluation:	At the end of the exposure test, visually examine all test samples for evidence of surface coating wear, including cracking, color change/fading, efflorescence, or other objectionable effect. Use unexposed controls as reference specimens for each visual evaluation.
	¹ ASTM G53-96 has been replaced by ASTM G154-00ae1, "Standard Practice for Operating Fluorescent Light Apparatus for UV Exposure ofNonrnetalic Materials".
5. EQUIPMENT:	(i) Atlas UV/Condensation Screening Device. Model UC-I MII# A07913, equipped with eight UVA- 340 fluorescent UV lamps. (ii) Q-Panel QUV Accelerated Weathering Tester, equipped with eight UVA-340 Fluocescent UV lamps, MII # A14086.
6. PROCEDURE:	Uncut brick, stone and concrete samples provided by the Client were cut into approx. 2 1/2- W x 8 1/2-L x 3/4 -D specimens by Bodycote. The Client and assistant visited Bodycote on 23-0ct-2002 to apply various tinted paint formulations and procedures to the face of arbitrarily selected specimens. The specimens were identified as shown in 3.). A minimum of One Control specimen was prepared for each type of applied tint. Each specimen was secured to the exposure frame. The frame was then positioned inside exposure cabinet (i). The first 652-hrs exposure time was completed in exposure cabinet (i). The remaining 348 hrs was completed in exposure cabinet (ii). After the final exposure period, the test specimens were removed from exposure cabinet (ii), inspected according to the specification described in 4.), and then re-packaged for return to the Client.
7. RESULTS:	The test was completed on 31-Dec-2002. The test specimens were exposed for a total period of 1000 hrs. Side-by-side comparisons of exposed and control specimens were made. For the specimens subjected to the Perma Tint tinting process, our visual observations of exposed specimens verses the unexposed controls revealed no evidence of cracking, fading, color change, efflorescence or other evidence of coating degradation.
8. CERTIFICATlON	This letter is to certify that the test described herein was carried out in accordance with the procedure described in 6 above, and that all equipment used was in calibration.
