1 Scope
This document specifies two general test methods, Method A and Method B, to be used
for the determination of the impact properties of unnotched and notched specimens
cut from thermoplastics pipes for the transport of fluids.
-
— Method A: unnotched method, for unnotched specimens cut from thermoplastics pipes for the transport of fluids.
-
— Method B: notched method, for specimens cut from thermoplastics pipes for the transport of fluids, into which a notch has been machined.
The use of Method A or Method B is determined by the relevant product standards.
This document is not intended as a reference test method for the determination of
the impact strength of pipes. ISO 3127, relating to the determination of the impact strength of pipes by means of a falling
mass, is the reference test method. However, this document can be used for scientific
research, materials testing or the examination of pipe when it is not possible to
take measurements in accordance with the reference method.
This document can be applied to either isolated batches or continuous production of
pipe.
