Description

This standard specifies six test methods for the determination of the apparent initial tensile strength in the circumferential direction per unit length of glass-reinforced thermosetting plastics (GRP) pipes.

  • The burst test (method A) is suitable for all types and sizes of pipes. It is the reference method.
  • The split disc test (method B) may not be suitable for pipes with helically wound reinforcing layers.
  • The strip test (method C) and the modified strip test (method D) are suitable for pipes with a nominal size of DN 500 and greater.
  • The restrained strip test (method E) is suitable for all types of pipes with a nominal size greater than DN 500.
  • The notched plate test (method F) is primarily intended for use for helically wound pipes of nominal size greater than DN 500 with a winding angle other than approximately 90°.

Results from one method are not necessarily equal to the results derived from any of the alternative methods.
