It shall be fastened to a steel or wood-faced steel beam of such dimensions that de? Hold or clamp the axtm segment in the stretched position. Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or Practice C Make two index marks 12 in. The bell or groove end of the second pipe shall be supported by a block.

Hydrostatic Test Method 8. Use distilled water, rain water, or tap water that is known to have no effect on test results. Off-Center Hydrostatic Joint Test No mortar or concrete coatings,? Place the gasket index mark at the zero point on the measuring scale and carefully roll the uncut gasket loop without sliding c49 stretching.
The samples are then pulverized to obtain percent passing a mesh sieve. Measure the width of the crack by means of a gage astj from a leaf 0. Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged. The performance of a gasketed pipe joint is affected by its geometric design, manufacturing tolerances, and variability in subgrade support of an installed pipe.
ASTM C497 – 18
Test Method A is the standard test and referee and will require 3 to 6 c4497 to complete. Without disturbing the measuring device, slide the gasket out of the joint recess. Measure the mass of the gasket to the nearest gram. Cylinder specimens of sizes other than 6 by 12 in.
Continue to boil for 30 seconds, and then cool. Use the last 6 h of the minimum drying time to determine whether or not the sample had obtained the proper dried mass. An additional block shall be used to transmit the force from the zstm machine to the test pipe joint. NOTE 5—The numbers in 7. These tests are performed to establish whether or not the installed step has sufficient strength to withstand c479 speci?
Apply the test load to the riser or frame as assembled to the? Each core sample is then placed in a separate container and dried in an oven for one to two hours at a temperature c947 and degrees Fahrenheit. This rate of loading shall be continuous until the speci?
Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test. Calculate the test load as follows: 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.
Joint Shear Test The test specimen is? Last previous edition approved in as C — 04e1. Run two tests on each core sample. The samples axtm be immersed in lubricant in a closed container. Report the results separately for each specimen.
The machines used for performing the three-edge-bearing tests shall be veri? 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? Examine the pipe during the extended period for existence of moist or damp spots.

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. The wood shall be sound, free of knots, and straight and true from end to end. The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the specifications. Alkalinity of Concrete Mixture 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.
Do not apply live steam to the water to shorten the preboil periods until 1 h of heating by gas or electricity has been completed. A statement will be included when proper data have been collected and analyzed.
