Gaines isolantes souples - Partie 2: Méthodes d'essai (IEC 60684-2:2025)
L'IEC 60684-2:2025 donne les méthodes d'essai pour les gaines isolantes souples, y compris les gaines thermorétractables, initialement conçues pour isoler les conducteurs électriques et les connexions des appareils électriques, même si elles peuvent être utilisées à d'autres fins. Les essais spécifiés sont conçus pour contrôler la qualité des gaines, mais il reste entendu qu'ils ne permettent pas d'établir entièrement l'aptitude de celles-ci à l'imprégnation ou à l'enrobage, pas plus que leur aptitude à être utilisées pour d'autres applications spécialisées. S'il y a lieu, les méthodes d'essai spécifiées dans le présent document sont complétées par des essais appropriés d'imprégnation ou de compatibilité en fonction des cas particuliers.
Cette quatrième édition annule et remplace la troisième édition parue en 2011. Cette édition constitue une révision technique.

Overview
EN IEC 60684-2:2025 - Flexible insulating sleeving: Methods of test specifies standardized laboratory test methods for flexible insulating sleeving (including heat‑shrinkable sleeving) used primarily to insulate electrical conductors and connections. The fourth edition (2025) updates normative references and introduces new and revised test procedures to help manufacturers, test laboratories and specifiers control sleeving quality. The standard clarifies that the listed tests are quality controls and may need supplementation (e.g., impregnation or encapsulation compatibility tests) for specialized applications.
Key topics and technical requirements
- Scope and test conditions: Standard and elevated/low temperature test atmospheres and specimen conditioning.
- Dimensional measurements: Methods for measuring bore, wall thickness and concentricity for textile, braided and extruded sleeving.
- Mechanical and thermal tests: Resistance to splitting after heating, heat shock, resistance to soldering heat, longitudinal change (clarified: performed on expanded sleeving), deformation under load at elevated temperature.
- Material properties: Density, thermal stability of PVC and related methods.
- New or revised test methods (2025 edition):
- Major update of normative references.
- Revised bore and wall thickness measurement methods (Clause 5).
- Clarified longitudinal change testing (Clause 11).
- Additional flame propagation method D (Clause 28).
- Additional sample preparation method for adhesive peel tests (Clause 56).
- New abrasion test (Clause 63).
- New volume resistivity method for semi‑conducting materials (Clause 64).
- New outgassing test (Clause 65).
- New resistance to weathering test (Clause 66).
- Limitations: Tests control quality but do not fully establish suitability for impregnation, encapsulation or other specialized uses without supplementary compatibility testing.
Applications and who uses it
- Manufacturers: product development, production quality control and batch acceptance for flexible sleeving and heat‑shrink tubing.
- Test laboratories: accredited testing to verify compliance with product specifications and safety requirements.
