Overview
EN 1367-2:2009 (CEN) - Tests for thermal and weathering properties of aggregates - Part 2: Magnesium sulfate test is the European reference method for assessing aggregate durability under cyclic chemical crystallization. The standard defines a laboratory procedure to evaluate how aggregates degrade when repeatedly immersed in a saturated magnesium sulfate solution and oven-dried. It is intended for type testing and for use in cases of dispute; alternate methods may be used for factory production control if an established correlation with this reference method exists.
Key topics and technical requirements
- Test principle: cyclic immersion in a saturated magnesium sulfate (MgSO4) solution followed by oven drying to induce crystallization/re‑hydration stresses in aggregate pores that cause disintegration.
- Specimens and sizing: standard procedure uses two specimens in the 10 mm to 14 mm fraction (Annex B gives guidance for other sizes and Annex C for complete grading).
- Test cycle: five cycles of immersion and drying (immersion at (20 ± 2) °C; drying at (110 ± 5) °C). Immersion and timing parameters are specified to reproduce the disruptive crystallization action.
- Measurement and reporting: degradation is quantified as the magnesium sulfate value (MS) - a percentage mass change calculated from the initial mass (M1) and the final mass retained on the 10 mm sieve (M2): MS = ((M1 − M2) / M1) × 100. Report the mean of two specimen results and include specimen details and sampling certificate where available.
- Apparatus and reagents: test sieves (EN 933-2), mesh baskets, temperature-controlled tanks, ventilated oven, density hydrometer (ISO 649-1) and a saturated MgSO4 solution prepared and density-checked per the standard.
- Precision and limitations: precision data are provided in Annex A for specific rock types. The method may be inappropriate for some carbonate aggregates, materials high in magnesium-bearing minerals, or cryptocrystalline quartz.
Applications
- Quality assessment and type testing of construction aggregates.
- Contractual dispute resolution where a standardized reference test is required.
- Suitability evaluation of aggregates for use in concrete, asphalt and other construction products subject to weathering and salt exposure.
- Correlation work for establishing factory production control procedures based on alternative tests.
Who should use this standard
- Aggregate producers and quarry operators

La norme EN 1367-2:2009, intitulée "Tests pour les propriétés thermiques et de vieillissement des granulats - Partie 2 : Test au sulfate de magnésium", constitue un cadre fondamental pour évaluer le comportement des granulats face à des conditions de stress thermique et de vieillissement. Son champ d'application se concentre sur l'évaluation de la résistance des granulats lorsqu'ils sont soumis à l'immersion cyclique dans du sulfate de magnésium, suivie d'un séchage au four. Cela en fait un outil précieux pour des essais de type et en cas de litige, garantissant ainsi une homogénéité dans les tests réalisés en Europe. Parmi les forces de cette norme, on note la possibilité de tester une majorité des granulats disponibles en utilisant cette méthode. Cela assure une large applicabilité et soutient la standardisation des pratiques de test à l’échelle européenne. De plus, la précision de la méthode a été établie pour différents types de roches, comme mentionné dans l'Annexe A, ce qui renforce la fiabilité des résultats obtenus. Cependant, il est important de mentionner que la norme ne convient pas nécessairement à tous les types de roches. Des réserves ont été exprimées concernant certains granulats carbonatés et ceux contenant une forte proportion de matériaux riches en magnésium ou de quartz cryptocrystalline. Cela implique que, bien que cette norme soit robuste et pertinente pour la plupart des granulats, les utilisateurs doivent rester attentifs aux limitations spécifiques liées à certains types de matériaux. En conclusion, la norme EN 1367-2:2009 joue un rôle crucial dans le standard de test des granulats en garantissant des évaluations cohérentes et précises des propriétés thermiques et de vieillissement, tout en restant consciente de ses limites dans certaines applications.

The EN 1367-2:2009 standard presents a comprehensive methodology for assessing the thermal and weathering properties of aggregates, specifically through the magnesium sulfate test. This reference method is pivotal for type testing and serves as an authoritative baseline in situations of dispute regarding aggregate performance under cyclic immersion in magnesium sulfate, followed by oven drying. One of the primary strengths of this standard is its detailed framework, which ensures that the majority of aggregates can be evaluated effectively for their longevity and sustainability when exposed to harsh environmental conditions. The inclusion of a precision criterion for specific rock types, as outlined in Annex A, adds to the credibility and applicability of the test across various aggregate materials. This precision establishes a high level of confidence among stakeholders in the construction and civil engineering sectors who rely on the performance characteristics of aggregates. The relevance of the EN 1367-2:2009 standard cannot be overstated, particularly in industrial contexts where the durability of materials is paramount. The standard provides essential guidelines that promote consistency in testing methods, which is critical for quality assurance and regulatory compliance. Furthermore, while it allows for alternative methods in factory production control, it emphasizes the importance of establishing a valid relationship with the reference method. This ensures that any deviations in testing procedures do not compromise the reliability of results. However, it is important to acknowledge that the standard does outline certain limitations. Not all rock types may be amenable to testing using the magnesium sulfate method, particularly in cases involving specific carbonate aggregates or those with a significant presence of magnesium-bearing materials or cryptocrystalline quartz. This highlights the necessity for practitioners to judiciously consider the applicability of the standard based on the aggregate types at hand. In summary, the EN 1367-2:2009 standard provides a robust and effective framework for evaluating the thermal and weathering properties of aggregates. Its strengths lie in its detailed methodology, established precision, and significant relevance to construction practices, while also recognizing the need for careful consideration of its limitations in certain aggregate types.
