ASTM D1598 & ASTM D1599 Plastic Pipe Hydraulic Test Standards | Dual-Function Hydrostatic Tester Made by UnitedTest
UnitedTest is a professional original manufacturer of integrated hydrostatic pressure testing machines fully compliant with ASTM D1598 long-term constant pressure test and ASTM D1599 short-time hydraulic burst test for plastic pipe, tubing and matching fittings. Our all-in-one pipe pressure tester supports both test workflows in a single unit, catering to plastic pipe factories, third-party certification labs and pipeline R&D institutions worldwide.
ASTM D1598 – Long-Term Time-to-Failure Constant Internal Pressure Test
ASTM D1598 Standard Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal Pressure defines standardized lab procedures to measure the sustained pressure endurance of thermoplastic pipes and reinforced thermosetting resin pipes.
This standard subjects pipe specimens to stable constant internal hydraulic pressure for extended durations, recording the exact time elapsed until pipe rupture, creep or leakage failure occurs. It delivers critical long-term hydrostatic strength data used to calculate hydrostatic design basis (HDB), an essential metric to evaluate multi-year service reliability of buried fluid transport pipelines. The testing scope covers all thermoplastic and reinforced thermosetting resin pipe substrates for long-term structural performance characterization.
ASTM D1599 – Short-Time Hydraulic Burst Pressure Test
ASTM D1599 Standard Test Method for Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings establishes fast-cycle hydraulic testing protocols to measure instantaneous burst failure pressure of thermoplastic tubes, reinforced thermosetting resin pipelines and all associated pipe fittings.
Short-duration pressurization data generated from ASTM D1599 only reflects material behavior under matched short-term temperature, hoop stress and loading conditions. It serves quick factory incoming QC, batch verification and design validation but cannot represent the long-term creep resistance or permanent service strength of plastic pipe materials — a key distinction separating it from ASTM D1598 long-term endurance testing.
Our UnitedTest dual-purpose hydrostatic pressure test system precisely executes both ASTM D1598 constant-pressure long-duration tests and ASTM D1599 rapid burst tests with accurate pressure control, automatic failure time logging and complete test report output, fully satisfying all specimen clamping, temperature cycling and pressure holding requirements of both American industrial standards.
Test pipe sample Preparation Details:
Specimen: The specimen length between closures shall be at least five times the nominal outer diameter. or 12 inches, for pipes up to 6 inches, and at least three times the nominal outside diameter, or 30 inches, for larger pipes.
Dimensions: Measurement standards are in accordance with Practice ASTM D3567 or Test Method ASTM D2122
Preparation: A segment of thermoplastic pipe is inserted into a testing device, and hydraulic pressure is applied.
Test Procedure
The test comprises two procedures: Procedure A (calculates the specimen's burst pressure if the failure mode is to be determined) and Procedure B (determines if a specimen complies with a minimum burst requirement).
Procedure A:
The end closures of the specimen are attached and filled with the test fluid maintained at the test temperature. Then, the specimen is connected to the pressurizing device, ensuring that there isn’t any gas trapped inside. The specimen is usually conditioned by dipping in a liquid bath for an hour, at a temperature of 23 +/- 2 °C.. The pressure is increased uniformly and continuously until the specimen fails, and the time required is measured using a stopwatch. If the failure time is less than 60, the loading rate is reduced, and the test is repeated. Note that test failure time for all specimens should be between 60 s to 70 s. Values of applied pressure and time-to-failure are recorded.
Procedure B:
The specimen is prepared in the same way as in Procedure A. The pressure is increased uniformly and continuously, measuring the time along. The minimum burst pressure shall be reached or exceeded between 60 and 70s
This test method is suitable for establishing laboratory testing requirements for quality control purposes or for procurement specifications.

ISO 9080:2012 Plastics piping and ducting systems — Determination of the long-term hydrostatic strength of thermoplastics materials in pipe form by extrapolation.
The damage of PE-HD pipes is related to temperature, load size, and load duration. An increase in working pressure or working temperature can lead to a decrease in pipe damage time, that is, a shortened service life of the pipe. PE HD pipelines generally require a service life of 50 years or more, and current standards extrapolate the ability of pipes to withstand static hydraulic pressure for decades or even 100 years of use through shorter tests. The two standard systems of ISO and the United States have similar methods for predicting the long-term strength of PE-HD pipelines, both of which predict the long-term static water strength of pipes through hydrostatic testing. However, the theoretical basis of the two methods is slightly different.
ISO 1167: 2006 Thermoplastics pipes, fittings and assemblies for the conveyance of fluids -- Determination of the resistance to internal pressure.
ISO 1167 test method specifies a general test method for determining the resistance to internal hydrostatic pressure at a given temperature of thermoplastics pipes, fittings and piping systems for the transport of fluids. The method accommodates water-in-water, water-in-air and water-in-liquid tests.
Hydrostatic pressure testing is a valuable method for assessing the strength and integrity of pressurized systems, ensuring that they can meet operational demands without failure. Hydrostatic pressure testing can evaluate these items by filling pipelines, tanks, or containers with water before pressure is applied to detect any potential leaks or issues.
Hydrostatic pressure tester is critical across multiple industries, from pipeline engineering to industrial piping. It helps prevent costly failures or leaks by verifying whether the system can safely reach the specified pressure levels.
ASTM D1598 Standard Test Method for Time-to-Failure of Plastic Pipe Under Constant Internal Pressure. It is a fundamental test method used to determine the long-term hydrostatic strength and resistance of thermoplastic pipe by applying a constant internal pressure until the pipe specimen fails (ruptures). Which is critical for establishing hydrostatic design basis and ensuring long-term pipeline reliability.
ASTM D1599 is titled "Standard Test Method for Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings." It is a fundamental short-term, destructive pressure test used to determine the ultimate failure pressure (often called the "burst pressure") of thermoplastic pipe, tubing, or fittings under rapidly applied internal pressure at a specified temperature. Typically completed within 60–70 seconds, mainly for quality control and short-term design validation.
