Therefore, results of two properly conducted tests by the same operator on the same material should not differ by more than 0. 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. 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: Heat the water to boiling in not less than 1 h and not more than 2 h.

Aside from the procedures, this standard also details the significance and use of and the required test apparatus for each test.

Before making the compression test, cap the ends of the specimen in order to meet the requirements of Practice C Tighter joints will resist greater?

If a frame or riser has been designed to be? The supports for the zstm shall maintain a uniform invert elevation for both pipes.

Apply the test load to the riser or frame as assembled to the? The durometer shall be checked in accordance with Test Method D When the absorption, as computed by the Test Method B procedure, does not meet the speci? These tests are performed to establish whether or not the installed step has sufficient strength to withstand the speci? Weigh specimens weighing more than 1 kg to an accuracy of 1 g. The specimen under test shall be free of all visible moisture prior to the initiation of the test.

The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the specifications. 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.

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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Remove the remaining super? It shall be fastened to a steel or wood-faced steel beam of such dimensions that de?

If both the design strength and the ultimate strength are being determined, a speci? Place the upper bearing so adtm it is aligned with these marks.

Welded Splice Pull Test.

The test specimen shall be supported on a lower bearing of two parallel longitudinal strips and the x497 applied through an upper bearing Figs.

Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged. Additional timber blocks or similar supports are necessary to elevate the test pipes. Report the results separately for each specimen. The samples shall be immersed in lubricant in a closed container.

The difference in measurements is the stretched gasket height. Asrm statement will be included when proper data have been collected and analyzed. Test Method B is intended as an accelerated test that requires about 11? Originally approved in Continue the boiling for 5 h.

Cylinder specimens of sizes other than 6 by 12 in.

ASTM C497 – 18

If leakage of the joint initially occurs, the manufacturer is not prohibited from extending the test period up to a maximum of 24 h. Calculate the test load as follows: Current edition approved Oct. NOTE 7—This is also a quality control test result for the lowest concrete strength and lowest class of pipe produced. If proven watertight under these combined conditions, hairline cracks that do not leak shall not be cause for rejection.

At the end of the 3-h boiling period, turn off the heat and cool the specimen for a period of 3 h by running cold tap water into the boiler, or by placing the specimen in a separate container of water. The samples are then pulverized to obtain percent passing a mesh sieve. A number in parentheses indicates the year of last reapproval. Cylinder Strength Test Method Measure the width of the crack by means of a gage made from a leaf 0.

Dry specimens with a wall thickness of 1. The bearing faces of the lower strips shall not vary from a straight line vertically or horizontally by more than 1?

The second load is applied at a uniform rate until the speci? Run two tests on each core sample. Report the result as an average of the three 11? Wooden strips shall be straight, have a cross section of not less than 2 in. Without disturbing the measuring device, slide the gasket out of the joint recess.
