NormalisationIndex. décimale : 667.9 Revêtements et enduits Résumé : ISO has made the first step by renewing ISO2813. However, this solves just a part of the problem. The main issue is with the primary standard. All data are currently derived from just one reference, a quartz-glass wedge with no proof for the assumed linearity. Ideally a series of reliable reference materials would be developed and defined in order to prove and secure gloss references over a range of values rather than just one or two points. A series of references would also prove or disprove the assumed linearity of the calibration line. Thorough scientific research seems to be required to define the effects of roughness and wavelength in order to develop a primary-standard that puts ISO and ASTM in-line and that leaves no room for questions. Ideally these primary standards are of an accuracy level at least tenfold better than those of today's commercial glossmeters. Scientific research on a global definition of gloss would be of great use to the industry. All specifications on gloss should be checked for feasibility and correctness. Although gloss is a generally accepted appearance criteria for quality control in many indutries, recent revelations on gloss standards require us to rethink the way we consider the accuracy of our obtained results.

Revêtements:PeintureIndex. décimale : 667.9 Revêtements et enduits Résumé : Esthetic properties are become increasingly important in today's industry. In the 2Oth century gloss measurements became a standard QC parameter when it comes to validate the esthetics of coated surfaces. Readings from glossmeters and tight gloss-criteria set in finishing specifications are these days leading appearance guidelines.
Coating manufacturers, QC-organizations and suppliers of-test-equipment as well specify or claim very tight boundaries for gloss levels. But are these claims and specifications feasible ?En ligne : https://drive.google.com/file/d/1qRqKWrkVXHFhhZ96L71RqbJ_uxDoZ0w0/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=23501
