J <br />t <br />f1 <br />shall be capable of meeting the performance requirements for each quality characteristic <br />shown in Table 1. <br />Quality <br />ASTM Test <br />Performance Requirements <br />Characteristics <br />:Method <br />r <br />Adhesion <br />_ ......_.. <br />D3359 — Method <br />......... . _ _ .._..._ .............. <br />Adhesion (Retention of Coating) over 90% of test area (Tape and <br />'B <br />;knife test). <br />_....._._ <br />Corrosion <br />B117 & 131654 <br />. _. <br />._. __.._.__._.. .......... ... .. _......... <br />Corrosion Resistance over 3,500 hours (Scribed per D1654; failure <br />Resistance <br />mode is accumulation of 1/8" coating loss from scribe or medium <br />_ <br />#8 blisters). <br />Impact <br />ry <br />'132794 <br />-im act Resistance over 60 inch lb. ___� '___ _ _ _ . <br />(Forward impact _u__ sing 0.62_5" <br />Resistance <br />ball). <br />Weathering <br />Resistance <br />D822,132244, <br />'D523 (60° <br />!Weathering Resistance over 1,000 hours (Failure mode is 60% loss <br />lof gloss or color variance of more than 3 delta -E color units). <br />Table 1 — Coating Performance Requirements <br />D. Material for fence pickets shall be 3/4" square x 16ga. tubing. The cross - sectional shape <br />of the rails shall conform to the manufacturer's ForeRunnerTM design with outside cross - <br />section dimensions of 1.50" square and a minimum thickness of l4ga. Picket holes in the <br />ForeRunnerTM rail shall be spaced 4.70" o.c. Picket retaining rods shall be 0.125" <br />diameter galvanized steel. Posts shall be a minimum of 2 -1/2" square x 12ga. All posts to <br />have decorative ball post cap. High quality PVC grommets shall be supplied to seal all <br />picket -to -rail intersections. <br />2.03 FABRICATION <br />A. Pickets, rails, and posts shall be precut to specified lengths. ForeRunnerTM rails shall be <br />pre - punched to accept pickets. <br />B. Grommets shall be inserted into the pre - punched holes in the rails and pickets shall be <br />inserted through the grommets so that pre - drilled picket holes align with the internal <br />upper raceway of the ForeRunnerTM rails. (Note: This can best be accomplished by using <br />an alignment template.) Retaining rods shall be inserted into each ForeRunnerTM rail so <br />that they pass through the predrilled holes in each picket, thus completing the panel <br />assembly. <br />C. Completed panels shall be capable of supporting a 400 lb. load (applied at midspan) <br />without permanent deformation. Panels without rings shall be biasable to a 25% change <br />in grade; panels with rings shall be biasable to a 12.5% change in grade. <br />D. Gates shall be fabricated using Aegis P1usTMpanel material and gate ends having the same <br />outside cross - section dimensions as the ForeRunnerTMa rail. All rail and upright <br />intersections shall be joined by welding. All picket and rail intersections shall also be <br />joined either by welding or by the same retaining rod process used for panel assembly. <br />' 06/05 02444 -3 03- 4138.B <br />
