SCOPE: THIS STANDARD SHOWS SOLVENT CEMENT JOINING AND P.V.C. PLASTIC CONDUIT INSTALLATION. SOLVENT CEMENT JOINING INSTRUCTIONS FOR SOLVENT CEMENT JOINING AND INSTALLATION OF P.V.C. PLASTIC CONDUIT AND FITTINGS ALL PLASTIC CONDUIT AND FITTINGS TO BE JOINED SHALL BE EXPOSED TO THE SAME TEMPERATURE CONDITIONS FOR A REASONABLE LENGTH OF TIME BEFORE ASSEMBLY. MAKE CERTAIN THAT ALL FOREIGN MATTER HAS BEEN WIPED FROM BOTH THE CONDUIT AND FITTING (AT JOINT). THE CONDUIT SHOULD BE INSERTED DRY NOT OVER HALFWAY INTO THE FITTING TO MAKE A GOOD INTERFERENCE SOLVENT CEMENT JOINT. INSPECT CEMENT CONTAINER FOR PROPER CHECK DATE. CEMENT OVER 12 MONTHS OLD SHOULD NOT BE USED. ABS CEMENT SHALL NOT BE USED ON PVC CONDUIT. APPLY A LIBERAL AND UNIFORM COAT OF CEMENT TO THE MATING ZONE OF THE FITTING AND CONDUIT. IT MUST BE EMPHASIZED THAT MOST JOINT FAILURES ARE CAUSED BY DRY JOINTS WHERE AN INSUFFICIENT COATING OF CEMENT IS APPLIED, OR WHEN CEMENT HAS EVAPORATED DUE TO HIGH TEMPERATURE CONDITIONS. WORK FAST! SLIP CONDUIT STRAIGHT INTO THE FITTING WITH A SLIGHT TWIST UNTIL IT BOTTOMS. HOLD THE JOINT FOR 15 SECONDS (ONE MINUTE IN EXTREME COLD WEATHER) SO THAT THE CONDUIT DOES NOT PUSH OUT OF THE FITTING. DO NOT TWIST OR DRIVE CONDUIT AFTER INSERTION IS COMPLETE. THE JOINED MEMBERS SHALL BE CURED FOR FIVE MINUTES OR MORE BEFORE THEY ARE HANDLED. (IN COLD OR DAMP WEATHER, THIS INTERVAL SHOULD BE INCREASED TO ALLOW FOR THE SLOWER EVAPORATION OF THE SOLVENT.) MINIMUM TRENCH WIDTHS MAY BE UTILIZED BY ASSEMBLING CONDUIT ABOVE GROUND (ALLOWING FOR CEMENT CURE PERIOD) AND LOWERING THE PREASSEMBLED CONDUIT BANK INTO THE TRENCH. BE SURE TO WIPE OFF THE EXCESS CEMENT THAT IS LEFT ON THE OUTER SHOULDER OF THE FITTING. CARE SHOULD BE EXERCISED TO PREVENT EXCESS CEMENT FROM BEING FORCED INTO THE FITTING AT THE INSIDE SHOULDER OF THE CONDUIT. PLASTIC BRISTLE BRUSHES SHOULD NOT BE USED. (THE CEMENT WILL DISSOLVE THE BRISTLES.) A LARGE BRUSH SHOULD BE USED WITH THE MAXIMUM SIZE PERMITTED BY THE WIDTH OF THE FITTING SOCKET. CANS OF CEMENT SHOULD BE KEPT COVERED AND AWAY FROM EXCESS HEAT AND FLAMES WHEN NOT IN USE. QUART CANS ARE GENERALLY THE LARGEST PRACTICAL SIZE TO USE SINCE THE CEMENT DRIES RAPIDLY. USE ONLY SOLVENT CEMENT AS FURNISHED OR RECOMMENDED BY THE CONDUIT MANUFACTURER. SOLVENT CEMENT THINNER, MAY NOT BE USED FOR THINNING CEMENT WHICH HAS THICKENED.

PLASTIC CONDUIT AND FITTINGS (CONTD.) USE A FINE TOOTHED SAW OR RACHET TYPE CUTTER TO CUT CONDUIT LESS THAN TWO INCHES IN DIAMETER. A FINE-TOOTH WOOD SAW SHOULD BE USED ON CONDUIT ABOVE TWO INCHES IN DIAMETER. THE CONDUIT MUST BE CUT STRAIGHT AND CLEANED OF BURRS. CONDUIT TRANSITIONS FROM SCH. 80 OR SCH. 40 TO TYPE EB CONDUIT MUST BE CHAMFERED ON INSIDE EDGE. USE KNIFE OR HALF ROUND FILE. IN CASES WHERE A JOINT IS MADE UNDER STRESS, DUE TO MISALIGNMENT, BENDS, OR OTHER FACTORS, THE JOINT MUST BE HELD RIGID IN SUCH A MANNER AS TO RELIEVE THE STRESS ON JOINT UNTIL THE CONDUIT IS BACKFILLED OR ENCASED. DUE TO EXPANSION AND CONTRACTION OF PLASTIC CONDUIT (ONE AND ONE-HALF INCHES PER 100 FEET FOR EVERY 20° F CHANGE IN TEMPERATURE), THE FOLLOWING PRECAUTIONS SHOULD BE TAKEN: a. ALLOW EXTRA CONDUIT AT EACH TIE-IN FOR EXPANSION OR CONTRACTION . b. BACKFILL FROM CENTER OF TRENCH BOTH WAYS OR FROM ONE TIE-IN POINT TOWARD THE OTHER END OF THE TRENCH. c. CONDUIT MUST BE CUT TO CORRECT LENGTH FOR TIE-IN AFTER BACKFILL IS COMPLETE AND EXPANSION OR CONTRACTION HAS STABILIZED. ALL CONDUIT TIE-INS ENTERING MANHOLE, VAULT, OR PULL BOX WALLS SHALL BE GROUTED INTO PLACE AND CONCRETE ENCASED FOR A DISTANCE OF 12 TO 15 INCHES OUTSIDE THE WALLS. TO MINIMIZE ACCIDENTAL MECHANICAL DAMAGE, CONDUIT SHOULD NOT BE LEFT EXPOSED IN AN OPEN TRENCH LONGER THAT IS ABSOLUTELY NECESSARY. IN TRANSPORTING LONG OF CONDUIT, PROVISION SHOULD BE MADE TO SUPPORT THE FULL LENGTH TO AVOID DAMAGE DUE TO EXCESSIVE OVERHANG. CONDUIT THAT IS TO BE STORED IN EXCESS OF TWO WEEKS PRIOR TO INSTALLATION SHALL BE PROTECTED FROM THE SUN. PROTECTION MAY CONSIST OF TARPS OR OTHER OPAQUE COVERINGS. CONDUITS SHALL NOT BE STACKED IN EXCESS OF 42 INCHES FOR STORAGE IF STORAGE IS TO EXCEED TWO WEEKS DURATION.

AFTER CLEANING THE NEW/EXISTING CONDUIT, PULL AN APPROVED MANDREL THROUGH EACH CONDUIT RUN TO SHOW ITS CAPABILITY TO ACCEPT THE PROPOSED CABLE. THE MANDREL SHALL HAVE DIAMETER , TYPE AND LENGTH WHICH IS ADEQUATE TO SIMULATE THE PROPOSED CABLE FOR THE INSTALLATION AND PER CITY STANDARDS. THE MANDREL SHALL BE APPROVED BY THE CITY REPRESENTATIVE. THE CITY REPRESENTATIVE SHALL OBSERVE ALL CLEANING AND MANDRELLING OPERATIONS. PRIOR TO CABLE PULLING , EACH CONDUIT SHALL BE CLEANED WITH A SWAB LUBRICATED WITH CITY APPROVED CABLE PULLING LUBRICANT, REPEATEDLY BACK AND FORTH FROM VAULT TO VAULT THROUGH THE ENTIRE LENGTH OF EACH CONDUIT, UNTIL THE CONDUIT IS COMPLETELY FREE OF ALL DIRT AND DEBRIS AND THE SWAB EXITS THE CONDUIT FREE OF DIRT AND DEBRIS. DURING CABLE PULLING, A LUBRICATED SWAB SHALL BE INSTALLED ON THE LEADING END OF THE CABLE WHERE THE PULLING LINE IS ATTACHED TO THE SWIVELED CABLE END TO PROVIDE ADDITIONAL CLEANING DURING THE CABLE PULLING OPERATION.
