A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense.
Procedure A is used to determine burst pressure of a specimen if the mode of failure is to be aztm. Procedure B is used to determine that a specimen complies with a minimum burst requirement. It is the responsibility of aastm uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Summary of Test Method 3. Data obtained by this test method are of use only in predicting the behavior of pipe, tubing, and? They are generally not indicative of the long-term strength of thermoplastic or reinforced thermosetting resin pipe, tubing, and?
Either the internal hydraulic pressure or the hoop stress may be listed in the requirements. NOTE 1—Many thermoplastics give signi? This may require agitation. If an air or other gaseous environment is used, provisions shall be made for adequate circulation.
Fluid environments that chemically attack the specimens shall not be used unless this effect is being studied.
In that case, the purpose of the test shall be included in the report. NOTE 2—Reinforced thermosetting resin pipe and? When the mode of failure of a piping system is to be determined, no reinforcement shall be used.
Suggested equipment for this test may include the following: The pressure gage shall be selected such that the? The gage should be equipped with a surge protection device. For larger sizes, the minimum length shall be not less than three times the outside diameter, but in no case less than 30 in. When solvent cements are used they shall meet the requirements of the relevant solvent cement speci?
ASTM D – PRESSURE TESTING OF PLASTIC PIPE
Attach specimen to the pressuring device, making certain no gas is entrapped when using liquids. The specimen shall ashm completely immersed in the conditioning medium. If failure time is less than 60 s, reduce the rate of loading and repeat the test. The time to failure for all specimens shall be between 60 and 70 s. Closures shall be designed so that they do not cause failure of the specimen.
Free-end closures shall be used for referee tests. NOTE 4—Free-end closures fasten to the specimen so that internal pressure produces longitudinal tensile stresses in addition to hoop and radial stesses in the pipe wall.
Restrained-end closures rely on a rod through the specimen or an external structure to resist the end thrust. Stresses in the wall of restrained-end specimens act in the hoop and radial directions only. The test results will re? 1d599 determine that the specimen complies with a minimum burst requirement the specimen shall burst between 60 and 70 s, or the minimum burst pressure shall be reached or exceeded between 60 and 70 s. For reinforced thermosetting pipe use minimum reinforced wall thickness.
For reinforced thermosetting pipe, wall thickness and outside diameter shall be reinforced dimensions only. Unreinforced thicknesses shall also be reported.
