ASTM C497 – 18
Continue the boiling for 5 h. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The second load is applied at a uniform rate until the speci? Satm the test load to the riser or frame as assembled to the?
Originally approved in Measure the width of the crack by means of a gage made from a leaf 0. Continue to boil for 30 seconds, and then cool. The load shall be applied either at a single point or at multiple points dependent on the length of the specimen being tested and the rigidity of the test frame. 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 astn For self-lubricating gaskets, the tube containing the lubricant must be rolled over the gasket body and held under slight pressure as the measurement is taken.
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. When the effervescence has subsided, heat the mixture to boiling. A calibration curve shall be used.

asstm Without disturbing the measuring device, slide the gasket out of the joint recess. 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. 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? In cases of disagreement arising from differences in values reported by the 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.
NOTE 5—The numbers in 7. Do not apply live steam to the aastm to shorten the preboil periods until 1 h of heating by gas or electricity has been completed.
Manhole Step Test Methods 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. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Report sstm results separately for each specimen. The performance of a gasketed pipe joint is affected by astk geometric design, manufacturing tolerances, and variability in subgrade support of an installed pipe.
Flat Slab Top Test Method 5. NOTE 3—Ultimate strength of concrete pipe in the buried condition is dependent on varying soil bedding factors and varying failure modes and shall have no relationship to the ultimate strength as de? Measure the distance between the two sealing surfaces of the gasket with a adtm, micrometer, or dial gage. Report the result as an average of the three 11?
Next, slowly add 40 millilitres of standard 1-Normal hydrochloric acid, HCl, to the sample and water. The samples are then pulverized to obtain percent passing a mesh sieve.
Off-Center Hydrostatic Joint Test If leakage of the joint initially occurs, the manufacturer is not prohibited from extending the test period up to a maximum of 24 h. 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.
It shall be fastened to a steel or wood-faced steel beam of such dimensions that de? Make the initial inspection approximately 15 min after the test has begun. 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.
Absorption Test Method 7. Hydrostatic Test Method 8. Continue the boiling for 3 h. The gasket length is the distance measured at the point where the index mark retouches the scale.
Before making the compression test, cap the ends of the specimen to meet the requirements of Practice C or Practice C 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. Then remove the specimens and weigh in accordance with 7.
The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the speci?
