CO24SS6 : Participation to ILC Test of resistance of a stainless steel to pitting and crevice (ASTM G48 Met. A)


Reference of the ILC CO24SS6
References of test methods ASTM G48 Met. A
Frequency Each year
Main characteristics Speed of corrosion (loss of mass in a fixed exposure time, 72h - 2 temperatures 22° & 50°)
Other characteristics Density, size, depth of defects according to ASTM G46
  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 3
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 Stainless steel
Type of samples Parrallelepipeds
Approximate dimensions of samples 2 x (50x25x5 mm)
Specific preparation to be performed by the participant  Polishing and cleaning of specimens : See § 7-4 and 7-6 ASTM G48.
Grinding / Stripping of specimens: Do not perform any of these operations on specimens
It may be necessary to adapt their dimensions to the equipment (2 test pieces per supplied sample)
