ISO 9854.1 is an internationally recognized standard that focuses on pendulum impact strength determination using the Charpy method. This is for unnotched test pieces from thermoplastic pipes used in fluid transportation. This standard provides a general test method for assessing the impact strength of these test pieces.

While ISO 9854.1 is not intended to be used as a reference test method for evaluating the impact strength of complete pipes, it finds applicability in scientific research, materials testing, or situations where measurements according to the reference method are impractical.

The standard outlines detailed procedures for conducting a pendulum impact test on the test pieces, measuring the energy absorbed when a swinging pendulum strikes the specimen. The test results offer valuable insights into the material’s ability to withstand sudden impacts.

Class J – Charpy and Izod Automatic Impact Testing System complies with ISO 9854.1 standard.
