La m\u00e9thode Bresle pour les sels solubles<\/h2>
La m\u00e9thode Bresle (ISO 8502-6, ISO 8502-9) est le mode op\u00e9ratoire le plus r\u00e9pandu pour la mesure quantitative des sels solubles. Une cellule adh\u00e9sive transparente (Bresle patch) est coll\u00e9e sur la surface m\u00e9tallique pr\u00e9par\u00e9e ; un volume connu d’eau d\u00e9min\u00e9ralis\u00e9e est inject\u00e9 dans la cellule \u00e0 la seringue, laiss\u00e9 en contact environ une minute avec agitation, puis pr\u00e9lev\u00e9. La conductivit\u00e9 \u00e9lectrique de la solution, mesur\u00e9e avec un conductim\u00e8tre \u00e9talonn\u00e9, est proportionnelle \u00e0 la concentration de sels sur la surface. Convertie en mg\/m\u00b2 au moyen de formules \u00e9tablies, elle donne la valeur de contamination saline. Il existe des kits complets comprenant cellules, seringues, conductim\u00e8tre et solutions d’\u00e9talonnage. <\/p>
Le dust tape test<\/h2>
Le dust tape test (ISO 8502-3) mesure l’empoussi\u00e8rement r\u00e9siduel apr\u00e8s sablage : un ruban adh\u00e9sif transparent est appliqu\u00e9 sur la surface, puis la quantit\u00e9 et la taille des particules adh\u00e9rentes sont compar\u00e9es visuellement \u00e0 des \u00e9chelles de r\u00e9f\u00e9rence normalis\u00e9es (quantit\u00e9 de 0 \u00e0 5, taille de 1 \u00e0 5). Le r\u00e9sultat s’exprime en cat\u00e9gorie d’empoussi\u00e8rement (par exemple \u00ab dust quantity 2 \/ dust class 3 \u00bb). Pour les surfaces tr\u00e8s critiques, on utilise des kits avec cam\u00e9ras et logiciel d’analyse automatique d’images afin d’obtenir des r\u00e9sultats quantitatifs. <\/p>
Contamination organique<\/h2>
La v\u00e9rification de la contamination organique (huiles, graisses, hydrocarbures) s’effectue par des m\u00e9thodes indirectes : essai de rupture du film d’eau (water-break : l’eau ne s’\u00e9tale uniform\u00e9ment que sur une surface propre), essai \u00e0 l’eau color\u00e9e, kits de d\u00e9tection \u00e0 colorants fluorescents UV, et pr\u00e9l\u00e8vements au solvant avec analyse en laboratoire. Pour les applications critiques (a\u00e9rospatial, emballage alimentaire, m\u00e9dical), il existe des instruments portables \u00e0 fluorescence UV pour d\u00e9tecter les r\u00e9sidus d’hydrocarbures sur le m\u00e9tal. <\/p>
Applications<\/h2>
Les contr\u00f4les de contamination de surface sont exig\u00e9s par les cahiers des charges anticorrosion les plus s\u00e9v\u00e8res (milieux marins, offshore, industrie chimique) : typiquement 50 mg\/m\u00b2 de chlorures au maximum pour les syst\u00e8mes marins standard, et 20 mg\/m\u00b2 pour les milieux tr\u00e8s s\u00e9v\u00e8res. L’empoussi\u00e8rement doit g\u00e9n\u00e9ralement \u00eatre class\u00e9 \u00ab class 2 \u00bb ou inf\u00e9rieur avant l’application du primaire. La documentation des mesures (photo du Bresle patch, valeur de conductivit\u00e9, calcul de la contamination, comparaison aux sp\u00e9cifications) constitue la preuve objective du respect des modes op\u00e9ratoires de pr\u00e9paration. <\/p>
Normes de r\u00e9f\u00e9rence<\/h2>
Les normes de r\u00e9f\u00e9rence sont : l’ISO 8502-1 (extraction et analyse des produits de corrosion superficiels), l’ISO 8502-2 (chlorures sur surfaces nettoy\u00e9es), l’ISO 8502-3 (dust tape test), l’ISO 8502-6 (\u00e9chantillonnage Bresle) et l’ISO 8502-9 (\u00e9chantillonnage Bresle avec conductim\u00e8tre de terrain). L’\u00e9talonnage du conductim\u00e8tre se r\u00e9alise avec des solutions de KCl certifi\u00e9es ISO 17025 \u00e0 conductivit\u00e9 connue. Les kits de dust test doivent comporter des documents de r\u00e9f\u00e9rence visuels normalis\u00e9s. <\/p>
L’int\u00e9gration des kits de mesure \u00e0 des syst\u00e8mes de reporting num\u00e9rique (applications mobiles, logiciels d\u00e9di\u00e9s) permet de documenter int\u00e9gralement chaque inspection : donn\u00e9es d’\u00e9chantillonnage, photo du Bresle patch, g\u00e9or\u00e9f\u00e9rencement du point de mesure, calculs automatiques et production de rapports de campagne conformes aux normes. Ce niveau de documentation est fondamental dans les projets anticorrosion marins et offshore, o\u00f9 la conformit\u00e9 aux sp\u00e9cifications de pr\u00e9paration de surface est v\u00e9rifi\u00e9e par des inspecteurs certifi\u00e9s FROSIO ou NACE. <\/p>","protected":false},"excerpt":{"rendered":"
