Composeal Blue ASTM D 4551 Results   SGS U.S. Testing Company Inc. 1341 North 108th East Avenue Tulsa, OK 74116 Tel: 918 437-8333 Fax: 918 437-8487 January 17, 1997 Ms. Joan M. Hutchins Compotite Corporation 355 Glendale Blvd. Los Angeles, CA 90026 Reference: Report No. TS95-0681 (30mil) and TS 96-2594 (40 mil) Dear Ms. Hutchins: The above mentioned reports have been tested to ASTM D 4551-1991 and have complied with all the requirements. On the following pages is the list of tests procedures that are called for in ASTM D 4551 as well as the summaries of the test reports. Very truly yours, SGS U.S. Testing Company Inc.   sgd. Dale E. Holloway Tulsa Branch Director DEH/bk     ASTM D4551-1991 TESTS 1. Thickness per ASTM D 374, Method C. The average thickness obtained from multiple readings is reported for both samples. 2. Stress Strain Properties including tensile strength, modulus @ 100% elongation and ultimate elongation per ASTM D 412, method A. Die C (Dumbbell) was used for this evaluation. 3. Pinholes specimens taken from each sample were examined for pinholes as specified in ASTM D 4551, para. 11.3. 4. Resistance to Chemical Reagents per ASTM D 543, Procedure 1 (Weight and Dimensional Changes). a. Distilled Water - The percent weight loss for each test specimen is determined after immersion in distilled water @ 1200 F (490 C) for 24 hours. b. Soapy Water- The percent weight loss for each test specimen is determined after immersion in a soapy water solution @ 1200 F for 24 hours. Dehydrated white soap flakes were used for this evaluation. c. Hot Alkali Solutions - The waterproofness of each test specimen is determined after immersion in hot alkali solution maintained @ 1500 F (660 C) for 72 hours. Following the immersion procedure, the test specimens are subjected to the hydrostatics pressure test outlined in ASTM D 4551, Annex A.5. 5. Microorganism Resistance The resistance of the submitted PVC membranes to mold growth was determined in accordance with ASTM D 4551 Annex A.1. Six test specimens from each sample are inoculated with the specified test fungi and then placed in an incubation chamber for a period of 28 days @ 84.5 ± 1.80 F( min. 50% relative humidity). 6. Strength and Toughness Tests The durability of the submitted PVC membranes was evaluated in accordance with the following procedures listed in ASTM D 4551. a. Puncture Resistance(Annex A2)- Free falling dart method. Test specimens were mounted horizontally on a maple wood test substrate. An impact dart weighing 6.9 oz. (197 g) was dropped from a height of 3 feet onto the specimen surface. The specimens were then examined for evidence of failure (puncture). b. Indentation Resistance (Annex A3)- Test specimens were placed on a horizontal steel support plate. An 0.18" indenter head under a load of 120 lbs. is placed in contact with the specimen surface for a period of 30 minutes. The specimen is examined at test conclusion for evidence of failure (holes, tears,etc.) c. Folding Resistance (Annex A4)- Test specimens are exposed to temperatures maintained @ 0 + 2 0 F (-17+ 10 C) for 4 hours and then subjected to the folding and weight loading procedures specified in this method. At test conclusion the specimens are examined for cracks and other signs of failure. 7. Shrinkage per ASTM D 1204. Test specimens were examined for dimensional change after being subjected to 1580 F (700 C) for a period of 1 hour. 8. Hydrostatic Pressure Test per ASTM D 4551, Annex A5. The submitted PVC membranes were tested for waterproofness in the original condition and after being subjected to the above described strength tests and alkali resistance test. 9. Tear Resistance per ASTM D 1004. The average value for six test specimens is reported. 10. Volatility (Loss) per ASTM D 1203, Method A. Test specimens are placed in direct contact with activated carbon and expressed (in sealed containers) to a test temperature maintained @ 1580 F (700 C) for 24 hours. At test conclusion, the percent volatile loss is calculated and recorded.   SUMMARY OF TEST RESULTS:    Report NO.
