Continue the boiling for 5 h.

ASTM C – 18 – Standard Test Methods for Concrete Pipe, Manhole Sections, or Tile
The blocking or restraints shall be designed to avoid bene? Make the initial inspection approximately 15 min after the test has begun. Raise the pressure of the water in approximately 1 min to the required level and hold for the speci? Manhole Step Test Methods If a frame or riser has been designed to be?
ASTM C497 – 18
If being tested in a horizontal position, the gage shall be placed to measure pressure at or as close to as practical above the horizontal axis.
If leakage of the joint initially occurs, the manufacturer is not prohibited from extending the test period up to a maximum of 24 h. Do not apply live steam to the water to shorten the preboil periods until 1 h of heating by gas or electricity has been completed.
Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test.
Test Method B is intended as an accelerated f497 that requires about 11? For plain end pipe, no bell or spigot, the length L shall be the overall length.
A statement will be included when proper data have been collected and analyzed. Without disturbing the measuring device, slide the gasket out of the joint recess. Continue to boil for 30 seconds, and then cool. Warning—Block or restrain the test pipe assembly horizontally to prevent any inadvertent pipe movements. Place the upper bearing so that it is aligned with these marks. The samples shall be immersed in lubricant in a closed container. Additional timber blocks or similar supports are necessary to elevate the test pipes.
NOTE 5—The numbers in 7. If the ratio of length to diameter is less than two, make allowance for the ratio of length to diameter by multiplying the compressive strength by the applicable correction factor given in the following table determine values not given in the table by interpolation: When the effervescence has subsided, heat the mixture to boiling.
Before making the compression test, cap the ends of the specimen in order to meet the requirements of Practice C The performance of a gasketed pipe joint is affected by its geometric design, manufacturing tolerances, and variability in subgrade support of an installed pipe. Off-Center Hydrostatic Joint Test The user of this speci? Work Item s – proposed revisions of this standard. The total force on the joint is the sum of the resultants of the pipe weight, the water weight, and the force applied by the test machine see Fig.
Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or Practice C These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles.
Do not apply live steam to asrm water to shorten the preboil period until 1 h of heating by gas or electricity has been completed.
If leakage occurs, the manufacturer is not prohibited from extending the soak time to 24 h.
The test specimen is? Measure the point on the joint gasketbearing surface immediately under the point where the gasket measurement was taken. There shall be no visible leakage. The concrete alkalinity is the ratio of the mass of acid neutralized by powdered concrete divided by the mass of acid neutralized by a similar sample of pure calcium carbonate.
The attachments from the heads of each testing device to the rung of the step are to be sufficiently sturdy to preclude asm bending of the attachment and rung over the length of the attachment. Use the last 6 h of the minimum drying time to determine whether or not the sample had obtained the proper dried mass. Welded Splice Pull Test.
Continue the boiling for 3 h.
