In cases of disagreement arising from differences in values reported by asm 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.
ASTM C497 – 18
NOTE 2—As used in this speci? At the option of the manufacturer, either or both the lower bearing and the upper bearing shall extend the full length or any portion of the length of the specimen.
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. If both the design strength and the ultimate strength are being determined, a speci? 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.
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. Make two index marks 12 in.
Off-Center Hydrostatic Joint Test. Off-Center Hydrostatic Joint Test C4977 5—The numbers in 7. Test Method B is intended as an accelerated test that requires about 11? The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the speci? These tests are performed to establish whether or not the installed step has sufficient strength to withstand the speci? The second load as de? NOTE 4—There is no signi?
ASTM C – 18 – Standard Test Methods for Concrete Pipe, Manhole Sections, or Tile
This standard has been approved for use by agencies of the Department of Defense. Measure the mass of the gasket to the nearest gram.
c947 Hard rubber strips shall have a durometer zstm of not less than 45 nor more than The absorption, as calculated by the Test Method B procedure, shall be considered satisfactory when its value does not exceed a value that is 0. Warning—Block or restrain the test pipe assembly horizontally to prevent any inadvertent pipe movements.
Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or Practice C Apply the test load to the riser or frame as assembled to the?
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. Flat Slab Top Test Method 5.
Examine the pipe during the extended period for existence of moist or damp spots. Last previous edition approved in as C — adtm. Statements will be included for each when the proper data have been obtained and analyzed. The curved face shall be lined with a one-inch thick hard rubber strip.

Welded Splice Pull Test. Each core sample is then placed in a separate container and dried in an oven for one to two hours at a temperature between and degrees Fahrenheit. Cc497 wood shall be sound, free of knots, and straight and true from end to end. There is no widely accepted method of analysis for differential shear through the joints in buried concrete pipes. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Tighter joints will resist greater?
Cylinder specimens of sizes other than 6 by 12 in. The samples shall be immersed in lubricant in a closed container. Hold or clamp the gasket segment in the stretched position.
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.
Continue the boiling for 3 h. Measure the point on the joint gasketbearing surface immediately under the point where the gasket measurement was taken. A surfactant shall be added to c4977 water to minimize air bubbles from clinging to the gasket material.
