Additional timber blocks or similar supports are necessary to elevate the test asttm. Moisture or beads of water appearing on the surface of the joint shall not be considered as leakage. Use the last 6 h of the minimum drying time to determine whether or not the sample had obtained the proper dried mass. Continue to boil for 30 seconds, and then cool. A statement will be included when proper data have been collected and analyzed.

Make an index mark on the gasket cross-section with the?

ASTM C497 – 18

Wooden strips shall be straight, have a cross section of not less than 2 in. Originally approved in 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.

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. Examine the pipe during the extended period for existence of moist or damp spots. Apply the test load to the riser or frame as assembled to the?

Test Method A is the standard test and referee and will require 3 to 6 days to complete. For plain end pipe, no bell or spigot, the length L shall be the overall length. 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?

This rate of loading shall be continuous until the speci? 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?

Calculate the test load as follows: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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?

The test specimen shall be supported on a lower bearing of two parallel longitudinal strips and the load applied through an upper bearing Figs.

When the absorption, as computed by the Test Method Asm procedure, does not meet the speci? Historical Version s – view previous versions of standard.

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 adtm. If no access opening has been provided to the? There shall be no visible leakage. The samples shall be immersed in lubricant in a closed container.

Dry specimens with a wall thickness of 1. A calibration curve shall be used. If cores are cut from the wall of the pipe and tested, the c47 to diameter ratio shall lie between one and two after the curved surfaces have been removed from the cut asttm. 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. If being tested in a horizontal position, the gage shall be placed to measure pressure at or as close to as practical above the horizontal axis.

Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test. When the effervescence has subsided, heat the mixture to boiling.

Joint Shear Test The load shall be applied either at a single point or at multiple points dependent on the length of the specimen being tested and the rigidity of the test frame.

The curved face shall be lined with a one-inch thick hard rubber strip. Both pipes shall be supported so a uniform invert elevation is maintained.

If leakage occurs, the manufacturer is not aetm from extending the soak time to 24 h.

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

Measure the distance between the two sealing surfaces of the gasket with a vernier, micrometer, asgm dial gage. Therefore, no calculations of precision and bias are presently capable of being performed. Two alternative procedures for conducting the test are presented.

Heat the water to boiling in not less than 1 h and not more than 2 h. After drying and weighing as speci?
