ISO 9854-1:2023 — Charpy impact properties for thermoplastic fluid-transport pipes (Part 1)

← Back to all standards

ISO 9854-1 is the general Charpy pendulum impact method for test pieces cut from thermoplastics pipes used to transport fluids. To match this to your program, talk with our team.

What ISO 9854-1 Covers

It sets out the general Charpy impact method for specimens taken from thermoplastic pipe, with an unnotched option (Method A) and a notched option (Method B), the choice directed by the applicable pipe product standard.

How the Test Is Run

A specimen cut from the pipe wall is supported as a beam and struck by a swinging pendulum, and the energy absorbed in breaking it gives the Charpy impact strength; Method B uses a notched specimen.

Why It Matters

Charpy impact data characterizes the toughness of thermoplastic pipe material for specification and quality control; a calibrated pendulum, correct specimen preparation from the pipe, and controlled conditioning are essential.
