Pressures to PSIG 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.
If an air or other gaseous environment is used, provisions shall be made for adequate circulation. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Draft Adtm of Contents. The standard includes a material classification system and requirements for materials, mechanical properties, dimensions, performance, methods of test, and marking.
The requirements for pipe material and installation in sewer and drainage collection systems. This specification covers only machine-made fiberglass flanges and establishes the requirements for materials, workmanship, performance, and dimensions.
The specimen shall be completely immersed in the conditioning medium.
The load versus hoop deflection data is recorded. Either the internal hydraulic pressure or the hoop stress may be listed in the requirements.
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. Bolt Torque – Flanges shall withstand a bolt torque of at least 1. For larger sizes, the minimum length axtm be not less than three times the outside diameter, but in no case less than 30 in. A length of pipe is placed in compression test machine and is subjected to an increasing axial compressive load until failure occurs.
Chapter 5 Bridge Deck Slabs Bridge Engineering 1 Basic types of bridge decks In-situ reinforced concrete deck- most common type Pre-cast concrete deck minimize the use of local labor Open steel grid.
Long term performance of polymers 1. Chapter 5 Bridge Deck Slabs. Work Item s – proposed revisions of this standard. Refer also to 6. For design and pressure, the thermoplastic core and cover layers are not considered hoop stress bearing elements.
Poison s ratio can be determined from the hoop and axial strain gauge data. Free-end closures shall be used for referee tests.
Attach specimen to the pressuring device, making certain no gas is entrapped when using liquids. Type Method of manufacture Grade – Type of resin Class – Configuration of joining asym Pressure rating Flanges complying with this specification are also given numerical classifications relating to rupture pressure, sealing test pressure, and bolt torque limit.
It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The quality and testing of concrete and steel reinforcing and anchoring materials and the design and construction of concrete.

Cycles to Failure Failure Points 1, to 10, at least 3 10, toat least 3to 1, at least 3 1, to 10, at least 3 After 15, at least 1 Total at least 18 The cyclic Long Term Hydrostatic Strength LTHS of a pipe is obtained by an extrapolation of a log-log plot of the linear regression line for hoop stress versus cycles to failure.
The test should is conducted at maximum rated temperature for the component and joint. Precision and Bias 3 Cable ladder installation at S.
r1599 Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Procedure A is used to determine burst pressure of a specimen if the mode of failure is to be determined. Students use optical and digital land surveying instruments More information.
