Pre-registration to the ILC: FM-X-J1c Determination of J1c

FM-X-J1c

Reference of the ILC

FM-X-J1c

References of test methods

ASTM E1820

References of test methods for which the ILC can indirectly provide an assessment of performance

ISO 12135

 

 

 

These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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

For this ILC, there is a risk that the number of registrations is low. To ensure an enough number participants, a pre-registration procedure is put in place, as follows:

 

1 - Participants interested in participating pre-register using the registration form. No invoicing is made for this pre-registration;

2 - When at least 10 potential participants have pre-registered, CompaLab asks each of these pre-registrees to confirm their willingness to participate and what are the characteristics for which they commit to provide results;

3 - If at least 8 participants confirm their intention to participate, the CIL organisation concerned is engaged.

Main characteristics

J1c (Plain strain fracture energy on CT test specimens)
       

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.
