The supports for the pipes shall maintain a uniform invert elevation for both pipes. See also Practice C 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.

If a frame or riser has been designed to be? Current edition approved Oct. Raise the pressure of the atsm in approximately 1 min to the required level and hold for the speci?

A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Statements will be included for each when the proper cc497 have been obtained and analyzed. The crack is 0. Hard rubber strips shall have a durometer hardness of not less than 45 nor more than The test specimen is? Test Method B is intended as an accelerated test that requires about 11?

Measure the distance between the two sealing surfaces of the gasket with a vernier, micrometer, or dial gage. Tests include procedures for evaluating external load crushing strength, flat slab top, core strength, absorption, hydrostatic, permeability, manhole step, cylinder, gasket lubricant, joint shear, alkalinity, and gasket measurements.

This abstract is a brief summary of the referenced standard. External Load Crushing Strength.

ASTM C497 – 18

The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the specifications. Warning—Block or restrain the test pipe assembly horizontally to prevent any inadvertent pipe movements.

If no access opening has been provided to the? These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles. Cylinder specimens of sizes other than 6 by 12 in. The test specimen shall be supported on a lower bearing of two parallel longitudinal strips and the load applied through an upper bearing Figs. The interior vertical sides of the strips shall be parallel and spaced a distance apart of not more than 1 in. The difference in measurements is the stretched gasket height.

NOTE 1—The user of these test methods is advised that multiple points of load appllications to the upper bearing will permit use of lighter beams without excessive de?

The bearing face of the upper bearing shall not deviate from a straight line by more than 1? Before making the compression test, cap the ends of the specimen to meet the requirements of Asfm C or Practice C NOTE 7—This is also a quality control test result for the lowest concrete strength and lowest class of pipe produced.

If being tested in a vertical position, the gage shall be placed at or as close to as is practical above the joint or section being tested. Absorption Test Method 7.

Weigh the specimen immediately following blotting. Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test. Alkalinity of Concrete Mixture The volume of water is then measured directly in cubic centimeters or by pouring into a calibrated tube or the water displaced shall be weighed. Weigh specimens weighing more than 1 kg to an accuracy of 1 g.

No mortar or concrete coatings,? Make an index mark on the gasket cross-section with the?

Report the results separately for each specimen. 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 asm. Apply the test load to the riser or frame as assembled to the?

Dry specimens with a wall thickness of 1. The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the speci? 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.

Make the initial inspection approximately 15 min after the test has begun.

ASTM C – 18 – Standard Test Methods for Concrete Pipe, Manhole Sections, or Tile

Both pipes shall be supported so a uniform invert elevation is maintained. Last previous edition approved in as C — 04e1. Originally approved in These tests are performed to establish whether or not the installed step has sufficient strength to withstand the speci?

satm When the absorption, as computed by the Test Method B procedure, does not meet the speci? The difference in the dry mass and the immersed mass of the gasket, measured in grams, is the volume of the gasket in cubic centimeters.

Zstm performance of a gasketed pipe joint is affected by its geometric design, manufacturing tolerances, and variability in subgrade support of an installed pipe. NOTE 3—Ultimate strength of concrete pipe in the buried condition is dependent on varying soil bedding factors and varying failure modes and shall have no relationship to the ultimate strength as de? If proven watertight under these combined conditions, hairline cracks that do not leak shall not be cause for rejection.
