Frequency |
This ILC can be organised this year thanks to our preregistration procedure, which ensures an enough number of participants. |
|||
|
Main characteristics |
Loss of adhesion or cohesion after cycling at constant temperature (ISO 9046), after cycling with temperature variations (ISO 9047), after long term tension (ISO 10590), after exposure in water (ISO 10591), |
|||
|
after UV exposure (ISO 11431) |
||||
|
Other characteristics |
The standards ASTM C719 (after cycling with temperature variations), ASTM C1135 (after exposure to water), ASTM C1442 (after UV exposure) are not very different from the corresponding ISO reference standards |
|||
|
|
for this ILC. |

|
|
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. |
