Deflected tensile test on concrete prestressing steels

Presentation for participants

Reference of the ILC

DT24PS

 

 

References of test methods

ISO 15630-3

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

 

 

 

 

These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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

This ILC can be organised this year thanks to our preregistration procedure, which ensures an enough number of participants.

 

 

 

 

                       

Main characteristics

Fa,i (Rupture force under deflected tension)

   

Other characteristics

-

 

 

 

 

       

Format of the test results:

 

 

 

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.
