Last updated 16th March 2026
ASTM D2310 Standard Classification for Machine-Made “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Pipe
The ASTM D2310 provides classification plans for machine-made fiberglass pipes, which are officially referred to as a glass-fiber-reinforced thermosetting resin pipe. This classifies fiberglass pipe products into groups according to their design, resin, glass reinforcement, and proposed application. The test standard promotes equality and comparison in products of different manufacturers by establishing classifications accepted worldwide in various industries. By matching the products in the respective categories, the ASTM D2310 helps engineers, manufacturers, and users to choose a pipe suitable for the chemical conditions of structural, thermal, or service. Such a classification system is essential for businesses that require both accuracy and robustness in piping systems.

ASTM D2310 Introduction
Fiberglass-reinforced thermosetting-resin pipes, commonly referred to as FRP or “fiberglass” pipes, are a staple for industries requiring light yet durable piping systems. In contrast to heavy steel or concrete materials, fiberglass pipes provide superior corrosion resistance, chemical attack resistance, and temperature resistance. ASTM D2310 serves as the key to standardizing materials by specifying pipes into groups representative of their resin classification, reinforcement system, and service application. This classification brings about clarity in procurement, design, and testing to help ensure compatibility in various industrial projects. By adhering to the ASTM D2310 classification, manufacturers ensure that products are acceptable at established standards, while customers enjoy reliable performance and lifespan. The standard also ensures that safety, performance, and reliability are consistently maintained within industries such as water treatment, chemical processing, oil and gas, and power generation.

ASTM D2310 Testing Procedure and Requirements
Hydrostatic Design Basis Test
Pipes are subjected to internal water pressure at specified stress levels to determine long-term performance ratings.
Pipe Stiffness Classification
Deflection tests are performed by applying diametral loading to calculate the pipe stiffness factor (PS) at given diameters.
Resin Content Determination
Specimens are burned in a muffle furnace to measure the glass fiber and resin ratio, ensuring compliance with classification requirements.
Scope of ASTM D2310
Covers the classification of machine-made fiberglass (FRP) pipes.
Categorizes pipes according to the type of resin, the form of reinforcement, and service conditions.
Helps to assess mechanical performance and strengths.
Applied in industry to provide the piping system with corrosion resistance.
Provides a direct method of making a regular product selection and comparing products between manufacturers.
ASTM D2310 Equipment and Sample Preparation
Universal Testing Machine
Used for pipe stiffness tests; specimens cut to 300 mm length with edges smoothed to avoid stress risers.
Hydrostatic Pressure Vessel
Pipe specimens with standard diameters (≥150 mm) are capped and filled with water before applying controlled internal pressure.
Muffle Furnace
Small pipe coupons, typically 50 × 50 mm, are cleaned, dried, and subjected to ignition loss testing to determine resin-to-glass ratio.
Applications of ASTM D2310
Water distribution and wastewater systems.
Pipelines of chemical processing.
Piping systems of the oil and gas industries.
Infrastructure at sea and on shore.
Power plant cooling systems
Transport systems in the industrial fluids.
ASTM D2310 Common Challenges and Troubleshooting
Incorrect classification might be a result of a poor hydrostatic test, poor specimen preparation, or a wrongly established resin. The difference in the distribution of fibers, flaws in manufacturing,e or improper curing can influence the rigidity and the durability of the pipe. Proper sample preparation, equipment calibration, and test conditions should be taken to establish good classification results.
ASTM D2310 Aggregate Testing Technique, Processes, and Data Collection
Testing in ASTM D2310 involves testing of AH hydrostatic pressure, stiffness test in the form of additive loading in diameter, and on resin-glass ratio by ignition tests. Information that is gathered will consist of the values of resistance to pressure, stiffness parameters of the pipes, and the percentages of resin content. Such measurements are logged and compared to classification requirements in order to classify the fiberglass pipe in the right category.
ASTM D2310 Analysis, Results, and Interpretation
The test results are checked according to whether the pipe corresponds to the classification criteria of the strength, stiffness, and material composition. The long term pressure rating of the pipe is obtained through hydrostatic performance,e and the outcome of structural performance under external loads is obtained through the results of the stiffness. Correct resin content would ensure the reinforcement/matrix balance to provide mechanical strength and chemical resistance.
ASTM D2310 Problem and Solution
Problem: If there is an error in the measurement of hydrostatic pressure, the wrong stiffness or determination of the resin content, the incorrect classification can be made.
Solution: Proper specimen preparation, calibrated testing equipment, and carrying out tests in controlled laboratory conditions,s which will give correct classification results.
Factors to Consider for ASTM D2310
Speed
The process of testing involves several processes, such as hydrostatic testing and stiffness, which might take a moderate time.
Expert
It needs skilled technicians and engineers to create specimens, conduct tests on pressure, and interpret the results for classification.
Cost
The costs associated with testing are moderate and high because they require pressure testing equipment, stiffness testing machines, and other specific laboratory facilities.
