PAGE 05 iliolded Butt Fu,slon Fittings Poly Pipe's Butt Fusion Fittings are manufactured in compliance with ASTM D3261 (Standard Specifications For Butt Fusion Polyethylene Fittings), Measurement is done in accordance with ASTM D2122. A combination of D3261 and x2122 in paraphrased form is shown below. This paraphrased form is meant to be used only as a guideline: specific data and ASTM Specifications should be obtained directly from. ASTM. 1, Outside diameter measurements are to be taken 1/4" from end of fitting, The measurements may be made with micrometers, vernier or dial calipers, specially made tapered sleeve gauges, or circumferential wrap tapes, Of these instruments, the circumferential wrap tape is thought to be the most accurate and easiest to use. if micrometers or calipers are used, a minimum of 6 measurements must be taken to assure a true average diameter can be determined, once the average diameter'(g determined, compare the results against the tables in 13261 for outside diameter tolerances. 2. Wall thickness measurements are to be made with a cylindrical anvil tubular micrometer at a minimum of 6 locations to assure the wall minimum and maximum thicknesses have been found. Compare these results against the tables in D3261 for wail thickness tolerances. 3. out of round tolerances are not found in D3261 for butt fusion fittings, However, the industry generally ac- cepts the out of round tolerances for pipe found In ASTM D2513 (Standard Specifications for Gas Pressure Piping Systems) as also applicable to butt fusion fittings. If out of roundness is to be checked on butt fusion fittings, it should be done in the same manner as prescribed for roundable pipe in D2513 and D2122, which instructs as follows (paraphased): 3 A. Place the fitting in the Manufacturer's recommended re -rounding equipment, such as the clamping devices of a butt fusion machine, and tighten the clamps to achieve as much re -rounding as can be accomplished, 3 B. Using a micrometer, calipers, or similar measuring instruments, take a minimum of•6 measurements to assure the minimum and maximum outside diameters have been found, 3 C, Subtract the measured Minimum diameter from the maximum. The difference Is the actual out of round condition, Compare those results against the tables in 02513 for out of roundness, Note; All measurements are to be made at or near 730F(2300), Physical Data and Compatibility Poly Pipe's Polyethylene Fusion Fittings fully comply with the requirements of ASTM D2513 and API 15LE, Socket Fusion Fittings are manufactured in compliance with ASTM ia2683, and Butt Fusion Fittings are manufac- tured in compliance with ASTM D3261, Poly Pipe's PE Fittings are molded from pre -blended virgin resins in accordance with the material specifications listed in ASTM D1248. Poly Pipe's PE2406 fittings are molded from a Type 11, Class B, Category 5, Grade P-23/24 resin with a cell classification of 234433E as stated in ASTM D3350 and are, compatible for heat fusion with any Pipe manufactured from a like or similar resin. Poly Pipe's PE -3408 fittings are molded from a Type 111, Class C, Category 5, Grade P-34 resin with a cell classification of 3454340 stated in ASTM D3350 and are compatible for heat fusion with any pipe manufactured from a like or similar resin.
