PD18PC
Pendulum damping test on a paint coating
Presentation for participants
                   
 
Reference of the ILC: PD18PC
References of test methods: ISO 1522
Frequency: Each 3 years
Main characteristics t (damping time, which can be provided for both König and Persoz pendulums)
Other characteristics -
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:
Results are numerical. For each characteristic selected by the participant, 1 result shall be provided for each sample. The statistical computation will provide an assigned value with its attached uncertainty, values of standard deviations for repeatability, for reproductibility, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.
Number of samples per participant: 12
Product submitted to tests: Paint coating (on steel)
Type of samples: Plates
Approximate dimensions of samples: ± 100x100x5 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)
