Impact resistance testing of a paint coating

Presentation for participants

Reference of the ILC: IT21PC
References of test methods: ISO 6272-1
References of test methods for which the ILC can indirectly provide an assessment of performance ASTM E2794
These may be superseded standards, which some of the reference standards may have replaced, or EN or ASTM or ISO standards that are close but not exactly equivalent to the reference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: h-m (drop height and mass which causes cracking or peeling)
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: 1
Number of samples per participation: 8
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: Paint coated steel
Type of samples: Plates
Approximate dimensions of samples: 180x200x1 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)
