These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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

Rm, ReH, Rp0,2, A5d, Agt, hmax, c, fR, LM (Linear mass)

Other characteristics

ReL, Rt0,5, Ae, Z, E, h¼-h¾, Σei, a', β, b, GP (Percentage of failures in the grips of the tensile machine)

 

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.
