ashm Hydrostatic Test Method 8. 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. 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. The joint is de?

If proven watertight under these combined conditions, hairline cracks that do not leak shall not be cause for rejection. The specimen under test shall be free of all visible moisture prior to the c947 of the test. Stronger joints will resist greater?

ASTM C497 – 18

Wooden strips shall be straight, have a cross section of not less than 2 in. Place the upper bearing so that it is aligned with these marks. Measure the mass of the gasket to the nearest gram. Remove the remaining super?

Report the results separately for each specimen. All current methods of concrete pipe design assume that the installed pipes are uniformly bedded along the length of the pipeline. A number in parentheses indicates the year of last reapproval.

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? Run two tests on each core sample. Two alternative procedures for conducting the test are presented. Therefore, results of two properly conducted tests by the same operator on the same material f497 not differ by more than 0.


The second load as de? Place the gasket index mark at the zero point on the measuring scale and carefully roll the uncut gasket loop without sliding or stretching. NOTE 2—As used in this speci? The difference in the dry mass and the immersed mass of the gasket, measured in grams, is the volume of the gasket in cc497 centimeters. Off-Center Hydrostatic Joint Test.

Weigh specimens weighing more than 1 kg to an accuracy of 1 g. A calibration curve shall be used. Test Method B is intended as an accelerated test that requires about 11?

Flat Slab Top Test Method 5. These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles. 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. Work Item s – proposed revisions of this standard.

A vertical test load F shall be applied to the suspended portion of the test joint until the total differential load, including the weight of a pipe, is pounds per foot of pipe diameter.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test.

NOTE 5—The numbers in 7. 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. Continue to boil for 30 seconds, and then cool.

Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged. External Load Crushing Strength. Joint Shear Test
