Charpy impact pendulum test at ambient temperature (KU8 - medium energy)

Presentation for participants


Reference of the ILC: CY-X-MU8
References of test methods: ISO 148-1
References of test methods for which the ILC can indirectly provide an assessment of performance ASTM E23  ASTM A370 (KU8)
  These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference standards.
Frequency: Each year
Main characteristics: KU8 (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.
Number of products submitted to tests: 1
Number of samples per participation: 3
Max number of operators per participation: 1 (it is necessary to order as many participations as there are participating test operators)
Product submitted to tests: Steel
Type of samples: Parrallelepipeds
Approximate dimensions of samples: 120x15x15 mm
Specific preparation to be performed by the participant:  Machining of test specimens (2 test pieces per supplied sample)
Special notice for this ILC: Target energy range: 25-100 J.
