FRAME AND COVER NOTES:

1. MANHOLE CASTINGS SHALL BE MANUFACTURED

USING GOOD QUALITY GRAY IRON CONFORMING TO

CLASS 30 OF A.S.T.M. DESIGNATION A-48. THE

FINISHED CASTINGS SHALL BE OF UNIFORM

QUALITY, FREE FROM BLOWHOLES, POROSITY,

HARD SPOTS, SHRINKAGE DISTORTIONS OR OTHER

DEFECTS.

2. MANHOLE CASTINGS SHALL BE MANUFACTURED

SUCH THAT A COVER MANUFACTURED BY ANY ONE

FOUNDARY WILL FIT INTERCHANGEABLY INTO A

FRAME MANUFACTURED BY ANOTHER FOUNDRY

AND STILL MEET ALLOWABLE CLEARANCES AND

NON-ROCKING REQUIREMENTS. THIS WILL REQUIRE

MANUFACTURING OF THE MATCHING FACES ON THE

COVER AND THE FRAME TO CLOSE TOLERANCES.

3. THE OUTSIDE CIRCUMFERENCE OF THE VERTICAL

FACE OF THE COVER AND THE INSIDE

CIRCUMFERENCE OF THE VERTICAL FACE IN THE

FRAME RECESS SHALL BE MANUFACTURED TO

TOLERANCES SUCH THAT THE CLEARANCE

BETWEEN THE COVER AND FRAME WILL NOT

EXCEED 1/8" AT ANY POINT AROUND THE

CIRCUMFERENCE OF THE COVER. THE SEATING

SURFACES BETWEEN THE COVER AND FRAME

SHALL BE MACHINED SUCH THAT THESE SEATING

SURFACES SHALL MAKE FULL CONTACT FOR THEIR

FULL CIRCUMFERENCE TO PRECLUDE THE COVER

FROM ROCKING IN THE FRAME.

4. THE MANHOLE FRAME AND COVER SHALL BE

MARKED WITH LETTERING INDICATING THE NAME

OF THE MANUFACTURER AND THE YEAR WHEN THE

COVER OR FRAME WAS CAST.

5. MANHOLE COVERS SHALL INDICATE UTILITY

SYSTEMS STAMPED INTO THE LID.
