Bending test of a metallic piece

Presentation for participants

Reference of the ILC:

BE21FS

   

References of test methods:

ISO 7438  ASTM E290

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

ISO 15630-1

 

These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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

Pass/Fail (12 samples submitted to bending at 90° and 180° with 6 different mandrels of increasing severity: 0,25t - 0,5t - 1t - 2t - 4t - 8t, 2 samples per mandrel)

   

Format of the test results:

For results expressed as Yes/No type, samples are submitted to tests by sets of 2 items, with increasing severity, so that cut-off conditions for failure can be determined. The assessment of the results of participants is achieved by reference to this cut-off.

   

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 results expressed as Yes/No type, samples are submitted to tests by sets of 2 items, with increasing severity, so that cut-off conditions for failure can be determined. The assessment of the results of participants is achieved by reference to this cut-off.

Number of products submitted to tests:

1

Number of samples per participation:

12

Max number of operators per participation:

Approximate dimensions of samples:

200x50x8-10 mm

Specific preparation to be performed by the participant:

None (other than possible necessity to adapt dimensions of the test specimen to the equipment of the participant)
