After drying and weighing as speci? The machines used for performing the three-edge-bearing tests shall be veri? 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.
Test Method B is intended as an accelerated test that requires about 11? Each core sample is then placed in a axtm container and dried in an oven for one to two hours at a temperature between and degrees Fahrenheit.
The supports for the pipes astn maintain a uniform invert elevation for both pipes.
Your comments are invited either atm revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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. This standard has been approved for use by agencies of the Department of Defense. Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or Practice C For plain end pipe, no bell or spigot, the length L shall be the overall length.
The joint is de? If being tested in a vertical position, the gage shall be placed at or as close to as is practical above ast, joint or section being tested.
The blocking or restraints shall be designed to avoid bene? These tests are performed to establish whether or not the installed step has sufficient strength to withstand the speci? Calculate the test load as follows: Core Strength Test Method 6.

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

There is no widely accepted method of analysis for differential shear through the joints in buried concrete pipes. Wooden strips awtm be straight, have a cross section of not less than 2 in.
These test methods cover production and acceptance tests for concrete pipes, manhole sections, and tiles. The load shall be applied either c49 a single point or at multiple points dependent on the length of the specimen being tested and the rigidity of the test frame.

If the pipe shows moist or damp spots on the outer surface of the pipe at that time, continue the tests for a period not to exceed 24 h at the option of the manufacturer. Continue the boiling for 3 h. The difference in the dry mass and the immersed mass of the gasket, measured in grams, is the volume of the gasket in cubic centimeters. This abstract is a brief summary of the referenced standard. The crack is 0. Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged.
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. Make two index marks 12 in. Hard rubber strips shall have a durometer hardness of not less than 45 nor more than When the absorption, as computed by the Test Method B procedure, does not meet the speci?
