Information on the most widely used ASTM standards within the materials testing industry
ASTM D2290, Split disk test fixture, HDPE. GRP hoop tensile test
Hoop tensile strength of plastic pipes is designed based on the ASTM D2290, to determine the breaking strength for the pipe hoop tensile test. ASTM D2290 is a test method used to study the apparent tensile strength of plastic pipes using a specialized test fixture to pull apart a ring of pipe cut from a larger sample. The specialized fixture is called a self-aligning split disk, which applies a tensile stress to the ring from the inside of the pipe along its contour. Three different specimen types and procedures are available depending on the material being tested.
Testing Principle:
The
mechanical performance indicators such as elastic limit, elongation, and
elastic modulus of the material are determined through axial tensile
load. The test results can be used in research and development,
engineering design, and quality control fields.
General introduction
Hoop tensile strength of plastic pipes is designed based on the ASTM D2290, to determine the breaking strength for the pipe hoop tensile test. ASTM D2290 is a test method used to study the apparent tensile strength of plastic pipes using a specialized test fixture to pull apart a ring of pipe cut from a larger sample. The specialized fixture is called a self-aligning split disk, which applies a tensile stress to the ring from the inside of the pipe along its contour. Three different specimen types and procedures are available depending on the material being tested.
Testing Principle:
The mechanical performance indicators such as elastic limit, elongation, and elastic modulus of the material are determined through axial tensile load. The test results can be used in research and development, engineering design, and quality control fields.
Testing Method:
Pre-treatment: Treat the pipes according to standard requirements for temperature, humidity, and other conditions.
Loading Method: Apply axial tension using a split disc grip until the pipe ruptures.
Data Calculation: Calculate the apparent circumferential tensile strength based on the load at fracture and the dimensions of the pipe. It should be noted that this testing method requires attention to: different programs correspond to different pipe diameters (e.g., Programs A, B, and C are applicable to reinforced thermosetting pipes, thermoplastic pipes of any size, and thermoplastic pipes with a nominal diameter ≥ 4 inches, respectively), and the test results reflect the mechanical performance close to the testing conditions, not suitable for scenarios that differ significantly from actual use conditions.

Diameter range can from small to 60mm till 1500mm, 3000mm etc.,

ASTM D2290: Standard Test Method for Apparent Hoop Tensile Strength of Plastic or Reinforced Plastic Pipe
This test method covers the determination of the comparative apparent tensile strength of most plastic products utilizing a split disk or ring segment test fixture, when tested under defined conditions of pretreatment, temperature, humidity, and test machine speed. This test method is applicable to reinforced-thermosetting resin pipe regardless of fabrication method. This test method also is applicable to extruded and molded thermoplastic pipe.
