Charpy impact pendulum test at -50°C of a non alloyed steel

Presentation for participants

Reference of the ILC:



References of test methods:

ISO 148-1



Each year


Main characteristics:

KV2 (Absorbed energy), LE (Lateral expansion)

Other characteristics:

SFA (Fracture appearance)


Caution: The number of determinations may be low for the secundary characteristics, what may make inefficient the comparison between laboratories


Determination of the assigned values (“true values” for each characteristic):

By statistical computation of the totality of the results with possible selection on competence criteria (accreditation, validation by a reference body, quantity of tests performed in the year), test to detect possible collusion, merging of results not obtained in reproductibility conditions, suppression of technically unvalid results.


Type of statistical computation:

For numerical results, the statistical computation will provide an assigned value with its attached uncertainty, values of standard deviations for repeatability and reproductibility, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.
