ENVIROFLEX® for Fue*il and Generator Systems April l /996 rrtesr�rn atr .Ir±©1.7�ion1`ar�irn�n>F SyStecr►S Summary of Test Results Reported by Underwriter's Laboratory of Canada in April 1994 Leakage Test Samples of the pipes and fittings were subjected to 500 psi static pressure (twice the rated pressure) and held for 1 minute. Observations were made for any possible dam- age or leakage. The test was conducted at temperatures of 73.47, -40°F and 122°F. Results: The samples tested withstood the test conditions without leakage, rupture or other evidence of damage. Vacuum Test The pipes and fittings employed in the leakage test were subjected to an internal vacuum of 1 1.1 " of mercury for a period of 5 minutes. The test was conducted at 73.4°F. Results: The sample pipes and fittings withstood the applied vacuum without collapse. Hydrostatic Strength Test The pipe and fittings employed in the leakage test were subjected to a slowly increasing hydrostatic pressure of five times (1250 psi) the maximum rated pressure (250 psi) and held for one minute. Results: The sample pipes and fittings withstood the applied pres- sure without leakage, rupture or other evidence of damage. Low Temperature Bending Strength Test Representative samples of pipe of both sizes, 1 meter long, were conditioned at - 40°F for 24 hours, and then wrapped around mandrels having diameters equal to ten times the IDs of the primary piping. The samples were then subjected to leakage, hydrostatic and vacuum tests. Results: The sample pipes withstood all the test conditions without leakage, rupture or other evidence of damage. ESP400.03 (1 of 4) Pull Strength Test Two samples of all sizes of flexible primary pipes, 1 meter long, were, in turn subjected to longitudinal pull forces of 450 pounds for a period of ten minutes. It was required that the pipes withstand the longitudinal pull without any cracking of the pipes or coupling movement. Results: All samples withstood the longitudinal pull force without damage to the pipe or couplings. Permeability and Aging Tests Three samples of all sizes of primary pipe were filled with the following liquids and placed in a controlled environment maintained at a temperature of 1227. for a period of 90 days: - ASTM Reference Fuels A and C - ASTM Reference Oil No. 2 - Gasoline: premium & regular unleaded - Toluene - Ethanol - Methanol Following the exposure period the samples were tested for loss of liquid, hydrostatic strength and pull strength. Results: The samples retained at least 9996 of their liquids and with- stood the hydrostatic pressure tests of 1,250.18 psi with- out leakage and the pull tests of 450 pounds without any movement of the couplings or damage to the pipes. Conclusions This product is judged to be in compliance with ULC/ORD- CC 107 .4-1992. (Ducted Flexible Underground piping Sys- tems for Flammable and Combustible Liquids) and is ca- pable of being installed in accordance with the National Fire Code of Canada.
