The samples are then pulverized to obtain percent passing a mesh sieve. External Load Crushing Strength. Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test. Each core sample is then placed in a separate container and dried in an oven for one to two hours at a temperature between and degrees Fahrenheit.
The test specimen is?
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. Two alternative procedures for conducting the test are presented.
For plain end pipe, no bell or spigot, the length L shall be the overall length. The wood shall be sound, free of knots, and straight and true from end to end.
If leakage occurs, the manufacturer is not prohibited from extending the soak time to 24 h. Before making the compression test, satm the ends of the specimen to meet the requirements of Practice C or Practice C After drying and weighing as speci? There shall be no visible leakage. The total shear force on the joint is the sum of the resultants of the pipe weight and the applied force. Measure the distance between the two sealing surfaces of the gasket with a vernier, micrometer, or dial gage.
This rate of loading shall be continuous until the speci? Place the upper bearing so that it is aligned with these marks.
ASTM C497 – 18
Current edition approved Oct. When the absorption, as computed by the Test Method B procedure, does not meet the speci?
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices c4497 determine the applicability of regulatory limitations prior to use. Before making the compression test, cap the ends of the specimen in order to meet the requirements of Practice C Manhole Step Test Methods Off-Center Hydrostatic Joint Test.
NOTE 5—The numbers in 7. Then remove the specimens and weigh in accordance with 7. Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged. Apply the test asmt to the riser or frame as assembled to the? The shear strength limit shall be noted by a sudden reduction in the applied load or shearing of the concrete. 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.

Continue the boiling for 5 h. Absorption Test Method 7. All current methods of concrete pipe design assume that the installed pipes are uniformly bedded along the length of the pipeline. Hold or clamp the gasket segment in the stretched position. The difference in measurements is the asttm gasket height.
The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the specifications. Heat the water to boiling in not less than 1 h and not more than 2 h. Use distilled water, rain water, or tap water that is known to have no effect on test results.
Tighter joints will resist greater? The gasket length is the distance measured at the point where the index mark retouches the scale.
The blocking or restraints shall be designed to avoid bene? If the pipe shows moist or damp spots on the outer surface of the pipe at that time, continue the tests for a period not to exceed 24 h at the option of the manufacturer. Weigh the specimen immediately following blotting. Last previous edition approved in as C — 04e1.
For self-lubricating gaskets, the tube containing the lubricant must be rolled over the gasket body and held under slight pressure as c4497 measurement is taken. This standard has been approved for use by agencies of the Department of Defense.
The samples shall be immersed in lubricant in a closed container.
Titrate the mixture until the pH stays above 6. Report the results separately for each specimen. Permeability Test Method 9.
Perform tests by placing the specimen to be tested, with the spigot end down on a 4c97 rubber mat or its equivalent, weighted if necessary, and kept?
At the end of the 3-h boiling period, turn off the heat and cool the specimen for a period of 3 h by running cold tap water into the boiler, or by placing the specimen in a separate container of water.
