HU-X-PC1

Reference of the ILC	HU-X-PC1
References of test methods	ISO 6270-1 ASTM D4585 ISO 2808 ASTM B659 ASTM D1186 ISO 2813 ASTM D523 ISO 7724 Parts 1, 2 & 3 ISO 11664 Parts 1 & 4 ASTM E308 ISO 2409 ASTM D3359 Met. B ISO 4628 Parts 1 to 8 ASTM D610 ASTM D714 ASTM D1654

Frequency	For this ILC, there is a risk that the number of registrations is low. To ensure an enough number participants, 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	Temperature of tests 60°C (140F) - Selected exposure times for assessment: 0, 3, 9 and 28 cycles of 24h - Rating of defects due to ageing in accordance with ISO 4628-2 and -3 - Cross-test against ISO 2409
	after 28 cycles of 24h
Other characteristics	t (thickness of coating) in accordance with ISO 2808, Rating of defects due to ageing in accordance with ISO 4628-4 and 5, Gloss coefficients G20, G60, G85 in accordance with ISO 2813, Colorimetric parameters
	L-a-b* in accordance with ISO 7724-1 to 3
	Caution The number of determinations may be low for the secundary characteristics, what may make inefficient the comparison between laboratories

Format of the test results:	Results of some properties are numerical and some are expressed as a choice between several possibilities (categories).

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.
	For results expressed as a choice between several possibilities (categories), Gower indexes are computed from the results, which enables the calculation of assigned values, repeatability and reproducibility standard deviations, limits of alerts for bias and repeatability of the participant, indiviual values for uncertainty of results of participants.
