Environmental testing - Part 2-88: Tests - Test xd: Resistance of components and assemblies to liquid cleaning media
IEC 60068‑2-88:2025 establishes test methods for the resistance of electronic and electromechanical components, unpopulated circuit boards and assemblies to liquid cleaning media and cleaning processes, which are agreed between user and supplier for applications, where cleaning is required. These tests are not applicable to components, unpopulated circuit boards and assemblies, which are not intended to be subjected to cleaning processes.
Tests XD1 and XD2 primarily are intended for qualification testing of components and unpopulated circuit boards suitable for cleaning processes, but can be adopted as well to testing of material compatibility and specific cleaning media used in manufacturing processes of components and unpopulated circuit boards.
Test XD3 is intended to determine the resistance of electronic assemblies suitable for cleaning processes to the various cleaning processes to which they are exposed during manufacturing, including the effects of assembly and soldering processes.

Essais d’environnement - Partie 2-88: Essais - Essai xd: Résistance des composants et des assemblages aux produits de nettoyage liquides
L’IEC 60068‑2-88:2025 établit les méthodes d’essai de la résistance des composants électroniques et électromécaniques, des circuits imprimés nus et des assemblages aux produits de nettoyage liquides et aux processus de nettoyage, ayant fait l’objet d’un accord entre l’utilisateur et le fournisseur pour des applications pour lesquelles un nettoyage est exigé. Ces essais ne s’appliquent pas aux composants, aux circuits imprimés nus et aux assemblages qui ne sont pas destinés à être soumis à un processus de nettoyage.
Les essais XD1 et XD2 concernent essentiellement les essais de qualification des composants et des circuits imprimés nus prévus pour les processus de nettoyage. Toutefois, ils peuvent également être adoptés pour soumettre à essai la compatibilité des matériaux et les produits de nettoyage spécifiques utilisés dans le cadre du processus de fabrication des composants et des circuits imprimés nus.
L’essai XD3 a pour objet de déterminer la résistance des assemblages électroniques aux processus de nettoyage aux différents processus de nettoyage auxquels ils sont exposés pendant la fabrication, y compris les effets des processus d’assemblage et de brasage.
