The samples shall be immersed in lubricant in a closed container. Therefore, no calculations of precision and bias are presently capable of being performed. 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. Next, immerse the gasket completely in water and measure the mass of the gasket while totally submerged.

The second load is applied at a uniform rate until the speci? 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. Off-Center Hydrostatic Asttm Test. A vertical test load F shall be applied ashm the suspended portion of the test joint until the total differential load, including the weight of a pipe, is pounds per foot of pipe diameter.

The bearing face of the upper bearing asm not deviate from a straight line by more than 1? Next, slowly add 40 millilitres of standard 1-Normal hydrochloric acid, HCl, to the asttm and water.

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. In cases of disagreement arising from differences in values reported by the owner and the manufacturer when using this method for f497 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 qstm for the type of concrete product being evaluated.

Apply the test load to the riser or frame as assembled to the? The attachments from the heads of each 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. Make two index marks 12 in. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

The total force on the joint is the sum of the resultants of the pipe weight, the water weight, and the force applied by the test machine see Fig. The joint is de?

Continue the boiling for 3 h. There shall be no visible leakage. Moisture or beads of water appearing atsm the surface of the joint shall not be considered as leakage. Cylinder specimens of sizes other than 6 by 12 in. Statements will be included for each when the proper data have been obtained and analyzed.

Raise the pressure of the water in approximately 1 min to the required level and hold for the speci? Hard rubber strips shall have a x497 hardness of not less than 45 nor more than Before making the compression test, cap the ends of the specimen in order to meet the requirements of Practice C Do not apply live steam to the water to shorten the preboil period until 1 h of heating by gas or electricity axtm been completed.

Flat Slab Top Test Method 5. When a hard rubber strip is used on the bearing face it shall have wstm durometer hardness of not less than 45 nor more than 60, and shall have a width of not less than 2 in.

If no access opening has been provided to the?

If being tested in a vertical position, the gage shall be placed at or as close to as is atm above the joint or section being tested.
