Tensile test, geometry and linear mass of a hot rolled concrete reinforcing steel

Presentation for participants

Reference of the ILC:



References of test methods:

ISO 15630-1

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

ASTM A370  ASTM A615  ASTM A706


These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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



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.

Number of products submitted to tests:


Number of samples per participation:


Max number of operators per participation:
