Additional timber blocks or similar supports are necessary to elevate the test pipes. These tests are performed to establish whether or not the installed step has sufficient strength to withstand the speci? Continue the boiling for 3 h.
Absorption Test Method 7. The specimen under test shall be free of all visible moisture prior to the initiation of the test.
The alkalinity rating of the concrete mixture is one of the design criteria used to predict the service life of concrete pipelines where hydrogen sul? A number in parentheses indicates the year of last reapproval. Report the results separately for each specimen. Flat Slab Top Test Method 5. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Dry specimens with a wall thickness of 1.
ASTM C497 – 18
There shall be no visible leakage. If a frame or riser has been designed to be? NOTE 5—The numbers in 7.
Weigh specimens weighing more than 1 kg to an accuracy of 1 g. 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 crack is 0. Warning—Block or restrain the test pipe assembly horizontally to prevent any inadvertent pipe movements. Two alternative procedures for conducting the test are presented. Off-Center Hydrostatic Joint Test The performance of a gasketed pipe joint is affected by its geometric design, manufacturing tolerances, and variability in subgrade support of an installed pipe. No mortar or concrete coatings,?
Remove the remaining super? NOTE 2—As used in this speci?
Use the last 6 h of the minimum drying time to determine whether or not the sample had obtained the proper dried mass. Without disturbing the measuring device, slide the gasket out of the joint recess. In cases of disagreement arising from differences in values reported by the owner and the manufacturer when using this method for acceptance testing, the statistical bias, if any, between the laboratory of the owner and the laboratory of the manufacturer should be determined with each comparison being based on testing specimens randomly selected from the specimens available for the type of concrete product being evaluated.
All current methods of concrete pipe design assume that the installed pipes are uniformly bedded along the length of the pipeline. Manhole Step Test Methods Then remove the specimens and weigh in accordance with 7. NOTE 7—This is also a quality control test result for the lowest concrete strength and lowest class of pipe produced. See also Practice C Link to Active This link will always route to the current Active version of the standard. Weigh the specimen immediately following blotting.
These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Wooden strips shall be straight, have a cross section of not less than 2 in. Make two index marks 12 in. In cases of disagreement arising from differences in values reported by the owner and the manufacturer when using this test method for acceptance testing, the statistical bias, if any, between the laboratory of the owner and the laboratory of the manufacturer should be determined with each comparison being based on testing specimens randomly drawn from one pipe of the type being evaluated.
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.
Use distilled water, rain water, or tap water that is known to have no effect on test results. 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.
The rigid base shall be at least 6 in. The second load as de? Do not apply live steam to the water to shorten the preboil period until 1 h of heating by gas or electricity has been completed. Place the upper bearing so that it is aligned with these marks. 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. At the end of the 5-h boiling period, turn off the heat, and allow the specimen to cool in the water to room temperature by natural loss of heat for not less than 14 h nor more than 24 h.
The curved face shall be lined with a one-inch thick hard rubber strip.

A statement will be included when proper data have been collected and analyzed. Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test.
Cylinder Strength Test Method Permeability Test Method 9. Calculate the test load as follows: The bearing face of the upper bearing shall not deviate from a straight line by more than 1? The attachments to the rung are to be 31?
