The samples are then pulverized to obtain percent passing a mesh sieve. Both pipes shall be supported so a uniform invert elevation is maintained. A number in parentheses indicates the year of last reapproval. Then remove the specimens and weigh in accordance with 7. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the asgm of infringement of such rights, are entirely their own responsibility. 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.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM C – 18b Standard Test Methods for Concrete Pipe, Manhole Sections, or Tile
The second load as de? NOTE 7—This is also a quality control test result for the lowest concrete strength and lowest class of pipe produced.
Cylinder specimens of sizes other than 6 by 12 in. Joint Shear Test The machines used for performing the three-edge-bearing tests shall be veri?
Continue to boil for 30 seconds, and then cool. Link to Active This link will always route to the current Active version of the standard.
When the absorption, as computed by the Test Method B procedure, does not meet the speci? There is no widely accepted method of analysis for differential shear through the joints in buried concrete pipes.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are c947 provided as part of adtm standard. Measure the width of the crack by means of a gage made from a leaf 0.
A vertical test load F shall be applied to the suspended portion c479 the test joint until the total differential load, including the weight of a pipe, is pounds per foot of pipe diameter. Additional timber blocks or similar supports are necessary to elevate the test pipes. 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? Measure the distance between the two sealing surfaces of the gasket with a vernier, micrometer, or dial gage.
The attachments from the heads of astj testing device to the rung of the step are to be sufficiently sturdy to preclude any bending of the attachment and rung over the length of the attachment.
The bearing faces of the lower strips shall not vary from a straight line vertically or horizontally by more than 1? Two alternative procedures for conducting the test are presented. Without disturbing the measuring device, slide the gasket out of the joint recess. Off-Center Hydrostatic Joint Test Examine the pipe during the extended period for existence of moist or damp spots. Continue the boiling for 3 h. The crack is 0. It is informational 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.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. The bearing face of the upper bearing shall not deviate from a straight line by more than 1? Cylinder Strength Test Method Measure the mass of the gasket to the nearest gram. After drying and weighing as speci? 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.
Make two index marks 12 in.

If leakage of the joint initially occurs, the manufacturer is not prohibited from extending the test period up to a maximum of 24 h.
They shall be rectangular in cross section, having a width of not less than 2 in. The blocking or restraints shall be designed to avoid bene?
Calculate the test load as follows: 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. If the ratio of length to diameter is less than two, make allowance for the ratio of length to diameter by multiplying the compressive strength by the applicable correction factor given in the following table determine values not given in the table by interpolation: Manhole Step Astj Methods If both the design strength and the ultimate strength are being determined, a speci?
The astmm shall be checked in accordance with Test Method D A calibration curve shall be used. The rigid base shall awtm at least 6 in.
Wooden strips astn be straight, have a cross section of not less than 2 in. The specimen under test shall be free of all visible moisture prior to the initiation of the test. The user of this speci? Welded Splice Pull Test.
