ASTM C – 18 Standard Test Methods for Concrete Pipe, Manhole Sections, or Tile
For plain end pipe, no bell or spigot, the length L asym be the overall length. When the effervescence has subsided, heat the mixture to boiling. A surfactant shall be added to the water to minimize air bubbles from clinging to the gasket material.
Place the gasket index mark at the zero point on the measuring scale and carefully roll the uncut gasket loop without sliding or stretching.
See also Practice C Off-Center Hydrostatic Joint Test. The absorption, as calculated by the Test Method B procedure, shall be considered satisfactory when its value does not exceed a value that is 0. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Core Strength Test Method 6. If leakage occurs, the manufacturer is asm prohibited from extending the soak time to 24 h.
Moisture or beads of water appearing on the surface of the joint shall not be considered as leakage. They shall be rectangular in cross section, having a width of not less than 2 in.

If leakage of the joint initially occurs, the manufacturer is not prohibited from extending the test period up to a maximum of 24 h. NOTE 5—The numbers in 7. Therefore, no calculations of precision and bias are presently capable of being performed. A superscript zstm e indicates an editorial change since the last revision or reapproval.
ASTM C497 – 18
A vertical test load F shall be applied to the suspended portion of the test joint until the total differential load, including the aatm of a pipe, is pounds per foot of pipe diameter. The difference in measurements is the stretched gasket height. The curved face shall be lined with a one-inch thick hard rubber strip. If being tested in a vertical position, the gage shall be placed at or as close to as is d497 above the joint or section being tested. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
The interior vertical sides of the strips shall be parallel and spaced a distance apart of not more than 1 in. Report the results separately for each specimen.
The wood shall be sound, free of knots, and straight and true from end to end. Test Method B is intended as an accelerated test that requires about 11?

Heat the water to boiling in not less than 1 h and not more than 2 h. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Asm width of adtm All current methods of concrete pipe design assume that the installed pipes are uniformly bedded along the length of the pipeline.

Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged. Measure the point on the joint gasketbearing surface immediately under the point where the gasket measurement was taken.
