If an air or less, the specimen length between the end closures shall be not other gaseous environment is used, provisions shall be made less than five times the outside diameter of the pipe, but in no for adequate circulation. Unless otherwise stated, the tests shall case less than 12 in.
For larger sizes, the minimum be conducted at 23 6 2C 3.
The tolerance on other length shall be not less than three times the outside diameter, test temperatures shall be 6 2C 3. Fluid environments but in no case less than 30 in. In that case, the purpose of the test mens shall be tested.

Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings
Procedure referee tests. Restrained-end closures rely on a rod temperature. Attach specimen to the pressuring device, making through the specimen or an external structure to resist the end thrust. The specimen Stresses in the wall of restrained-end specimens act in the hoop and radial shall be completely immersed in the conditioning medium.
Because of this difference in loading, the expected hoop 9. The test the specimen fails, measuring the time with a stop watch. If results will reflect this difference in test method. The time to failure for all specimens shall be beyond the bottom thread or the bottom of the socket.
NOTE 5For purposes of determining the ultimate rupture strength of fittings, a metal band not extending more than one third of the threaded or NOTE 6If additional data can be obtained by continued pressurization socket depth, may be used: When the mode of failure of a piping system after failure as defined in Section 5 , it is the testers prerogative to do so is to be determined, no reinforcement shall be used.
Unreinforced thicknesses shall scribed in Procedure A 9. Strain gauges may be attached to the test specimen to measure dimensional changes in the axial directions. The data obtained from this test is used to calculate ultimate axial compressive stress capability of a pipe section by dividing the load at break, by the reinforced end area of the pipe section. The length change of the specimen in the axial direct is used to calculate the axial compressive modulus of elasticity, which is a measure of how much something will compress subject to compressive load.
A short length of pipe is loaded between two rigid parallel flat plates. The plates are moved together at a controlled rate, effectively flattening the pipe in the hoop direction.
The load versus hoop deflection data is recorded. If cracking, crazing, de-lamination, or rupture occurs, the corresponding load and deflection are recorded. Data obtained from this test is used to determine the load-deflection characteristics and pipe stiffness of the pipe, primarily used in burial design. A section of pipe is placed on two pipe supports to create a single span.
The pipe section is connected to a circulating hot water loop set at the desired test temperature. The mid span deflection of the pipe is measured and recorded at specific intervals over a minimum test time 1, hours.

Data obtained from this test is used to calculate the long term beam bending modulus of elasticity at various temperatures.
The long term beam bending modulus of elasticity is used in calculate the maximum allowable unsupported span length for pipe.
Short-Term Rupture Strength - Flanges shall withstand a short term internal pressure of at least four times their rated design pressure without damage to the flange. Bolt Torque - Flanges shall withstand a bolt torque of at least 1.
This specification covers only machine-made fiberglass flanges and establishes the requirements for materials, workmanship, performance, and dimensions. This standard defines: Type Method of manufacture Grade - Type of resin Class - Configuration of joining system Pressure rating Flanges complying with this specification are also given numerical classifications relating to rupture pressure, sealing test pressure, and bolt torque limit.
The test requirements provide classification and performance criteria for the purpose of qualifying the flanges published ratings.
This standard defines: Type - Method of manufacture Grade - Resin type Class - Liner type category - Configuration of joining system Pressure rating The test requirements provide classification and performance criteria for the purpose of qualifying the published ratings for the fittings. Elbow, couplings, tees, concentric reducers, flanges and joints in 3, 6, 12, 16 and 24 must be tested Fittings, couplings, and connections shall meet the following qualification test requirements: Short Term Pressure Strength - Each type of component and its field-jointed configuration shall be capable of sustaining a short-time hydrostatic pressure of at least 3 three times its static-rated pressure for 1 min without visible weeping or leakage.
Long Term Pressure Strength - Each type of component and its field-jointed configuration shall be capable of sustaining without leakage a minimum internal pressure of 2 two times the published static rating, at rated temperature. The minimum test duration is hours for static rated components.
The test should is conducted at maximum rated temperature for the component and joint.Unreinforced thicknesses shall also be reported.
The length change of the specimen and the corresponding load is recorded at set intervals during the test. We perform global on-site installation as well as service visits and we are of course available for support and advice daily, so you can rest assured your test equipment will have maximum up-time. If an air or other gaseous environment is used, provisions shall be made for adequate circulation.
The time to failure for each pressure level is recorded.
