ASTM D2105 Standard Test Method for Longitudinal Tensile Properties of Fiberglass Pipe and Tube
ASTM D2105 specifies the procedure for determining the tensile behavior of fiberglass-reinforced plastic pipes and tubes under controlled conditions. This encompasses such properties as tensile strength, modulus of elasticity, elongation, and energy absorption. The process is primarily applied in quality control, design, and acceptance tests of reinforced thermosetting resin pipe (RTRP) and reinforced polymer mortar pipe (RPMP). Alignment, grip force, and loading speed must be performed correctly to prevent specimen slippage or crushing during the test. The test assists in the structural performance of the pipe under axial loads.

Introduction to ASTM D2105
This procedure test aims to study the fiberglass pipe and tubing under longitudinal tension. It establishes the preparation, alignment, and testing of specimens to yield similar and repeatable data, particularly in materials employed in fluid transport, pressure, or structural applications.
ASTM D2105 Test Method
Sample Preparation
Pieces of at least 18 inches in length are cut off in fiberglass pipes or tubes. Tensile strength, elongation, and modulus, among other mechanical properties, are measured in the test. The pipes should be flawless and correctly fitted inside the testing machine. It is possible to use two speeds of testing: 0.20 0.25 in/min or 0.40 0.50 in/min.
Extension measurement
Deformation and loading are measured until the specimen fails.
ASTM D2105 Equipment and Sample Preparation
Sample Preparation
Specimens should be clean on the surface and conform to the dimensions. If a liner is available, it is measured to the standard thickness of a liner.
Equipment
One will need a calibrated tensile testing machine along with grips, an extension indicator (mechanical or electrical), and tools to measure wall thickness and diameter.
Results and Interpretation of ASTM D2105
The test results entail tensile strength, yield stress, elongation, modulus of elasticity, and energy absorption. These parameters demonstrate the performance of a fiberglass pipe under tension. Brittle samples can have a lack of yield point. For materials used in high-load environments, high modulus and elongation before break are desirable.

Tests Related to ASTM D2105
ASTM D2105 is related to tests including ASTM C33 concrete aggregates, ASTM D618 for plastics conditioning, and ASTM D638 for testing tensile properties of plastics.
Use of ASTM D105 Testing in Various Industries
The ASTM D2105 is applicable in such industries as water treatment, chemical processing, and structural infrastructures to ensure that fiberglass pipes are capable of internal pressure, tension, and installation stresses. It plays a significant role in determining reinforced composite pipes for use in aggressive or load-sensitive environments.
Challenges and Troubleshooting in ASTM D2105 Testing
Aligning the grip or evenly tightening it can lead to slippage or premature breaking. Over-tightened grips crush the specimens and give invalid results. Tensile can also be influenced by variation in the preparation or conditioning of the specimen. Valid data is important because dimensional measurement and alignment should be accurate.
Importance of ASTM D2105
The ASTM D2105 is important in determining the structural integrity and mechanical properties of fiberglass-reinforced pipes under tension. These pipes are commonly used in pressure systems, chemical plants, and infrastructure; hence, their tensile strength, elasticity, and failure behavior ensure their safety, reliability, and performance.
