Flattening test of a metallic pipe

Presentation for participants

Reference of the ILC:

FL-X-TU

   

References of test methods:

ISO 8492

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

ASTM A370

 

These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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

Pass/Fail (12 samples submitted to flattening with 4 different geometrical conditions of increasing severity)

Other characteristics:

Inside width of flattened test piece

 

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:

2

Number of samples per participation:

6

Max number of operators per participation:

1 (it is necessary to order as many participations as there are participating test operators)

Product submitted to tests:

For this ILC, products with 2 different thicknesses with 2 different flattening properties are provided for testing.

Type of samples:

Pipes

Approximate dimensions of samples:

Pipes: Ø20x1x50 mm - Pipes: Ø20x4x50 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)
