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.

A number in parentheses indicates the year of last reapproval. It is atm 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 crack is 0. 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.

The attachments to the rung are to be 31? Titrate the mixture until the pH stays above 6. Run x497 tests on each core sample. NOTE 7—This is also a quality control test result for the lowest concrete strength and lowest class of pipe produced.

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. Continue the boiling for 3 h.

Continue the boiling for 5 h. Perform tests by placing the specimen to be tested, with the spigot end down on a soft rubber mat or its equivalent, weighted if necessary, and kept? 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. Statements will be included for each when the proper data have been obtained and ast.

Tighter joints will resist greater? 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.

Absorption Test Method 7. 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.

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. 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 asm. NOTE 2—As used in this speci? The second load as de? No qstm or concrete coatings,? 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. If being tested qstm a horizontal position, the gage shall be placed to measure pressure at or as close to as practical above the horizontal axis.

ASTM C497 – 18

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.

The blocking or restraints shall be designed to avoid bene? Aastm specimens weighing more than 1 kg ast, an accuracy of 1 g. Continue awtm boil for 30 seconds, and then cool.

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 samples are then pulverized to obtain percent passing a mesh sieve.

If a frame or riser has been designed to be? The volume of water is then measured directly in cubic centimeters or by pouring 4c97 a calibrated tube or the water displaced shall be weighed.

If cores are cut from the wall of the pipe and tested, the length to diameter ratio shall lie between one and two after the curved surfaces have been removed from the cut core. The bell or groove end of the second pipe shall be supported by a block. The curved face shall be lined with a one-inch thick hard rubber strip. The wood shall be sound, free of knots, and straight and true from end to end.

The test specimen is? Stronger joints will resist greater? The shear strength limit shall be noted by a sudden reduction in the applied load or shearing of the concrete.

The specimen under test shall be free of all visible moisture prior to the initiation of the test.

The rigid base shall be at least 6 in. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Alkalinity of Concrete Mixture 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. If proven watertight under these combined conditions, hairline cracks that do not leak shall not be cause for rejection.

Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged. Gasket Lubricant Tests Historical Version s – view previous versions of standard. For plain end pipe, no bell or spigot, the length L shall be the overall length. Current edition approved Oct.

Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or 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.

Without disturbing the measuring device, slide the gasket out of the joint recess. This standard has been approved for use by agencies of c97 Department of Defense.
