ASTM C – 98 Standard Test Methods for Concrete Pipe, Manhole Sections, or Tile NO_PDF
Additional timber blocks or similar supports are necessary to elevate the astk pipes. Make two index marks 12 in. Place the upper bearing so that it is aligned with these marks. Calculate the test load as follows: Both pipes shall be supported so a uniform invert elevation is maintained.
Hard rubber strips shall have a durometer hardness of not less than 45 nor more than The user of this speci? Perform tests by placing the specimen to be tested, with c97 spigot end down on a soft rubber mat or its equivalent, weighted if necessary, and kept?

Welded Splice Pull Test. If leakage occurs, the manufacturer is not prohibited from extending the soak time to 24 h. Examine the pipe during the extended period for existence of moist or damp spots.
The wood shall be sound, free of knots, and straight and true from end to end. Measure the mass of the gasket to the nearest gram. Joint Shear Test 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 asfm type being evaluated.
The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the specifications.
Moisture or beads of water appearing on the surface of the joint shall not be considered as leakage. The samples are then pulverized to obtain percent passing a mesh sieve.
Place the gasket index mark at the zero point on the measuring scale and carefully roll the uncut gasket loop without sliding or stretching. 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.
The absorption, as calculated by the Test Method B procedure, shall be considered satisfactory when its value does not exceed a value that asym 0. Use distilled water, rain water, or tap water that is known to have no effect on test results. No mortar or concrete coatings,?
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Make the initial inspection approximately 15 min after the test has begun.
ASTM C497 – 18
When a hard rubber strip is used on the bearing face it shall have a durometer hardness of not less than 45 nor more than 60, and shall have a width of not less than 2 in.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test. 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.
Warning—Block or restrain the test pipe assembly horizontally to prevent any inadvertent pipe movements. The second load as de? Report the results separately for each specimen.
Off-Center Hydrostatic Joint Test The performance of a gasketed pipe joint is affected by its geometric design, manufacturing tolerances, and variability in subgrade support of an installed pipe. Dry specimens with a wall thickness of 1.
Apply the test load to the riser or frame as assembled to the? 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. Work Item s – proposed revisions of this standard. Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or Practice C If a frame or riser has been designed to be?
Hydrostatic Test Method 8. The machines used for performing the three-edge-bearing tests shall be veri? A calibration curve shall be used. This abstract is a brief summary of the referenced standard. Test Method A is the standard test and referee and will require 3 to 6 days to complete. Raise the pressure of the water in approximately 1 min to the required level and hold for the speci?
A surfactant shall be added to the water to minimize air bubbles from clinging to the gasket material. Make an index mark on the gasket cross-section with the? Run two tests on each core sample.
