Overview
EN 12637-1:2004 is a CEN test method for assessing the compatibility of elastic injection products with concrete, with a primary focus on polyurethane injection products (final injection products only - not water‑stopping foams). The standard defines a reference procedure that simulates long‑term contact between cured injection materials and the alkaline environment of concrete to assess changes in mechanical behaviour after water contamination and alkali exposure.
Key Topics and Requirements
- Test principle: Simulate water contamination during injection and long‑term alkali exposure by storing cured specimens in a 0.1 M KOH (caustic potash) solution. Compare with control specimens stored in air and in demineralised water.
- Specimen preparation:
- Cast discs in a specified steel mould (200 mm Ø cylinder enclosed by 270 mm plates).
- Cut discs into specimens 50 × 50 × 25 mm; a total of 12 specimens per product batch.
- For water‑contaminated samples, add 5% water (by weight) during mixing.
- Environmental conditions: Conduct tests at (21 ± 2) °C and (60 ± 10) % RH.
- Storage regimen: Triplicate specimens stored for 14 days in each condition: air, demineralised water, and 0.1 M KOH (for both supplied product and water‑contaminated product as specified).
- Mechanical evaluation:
- Use a compression testing machine complying with ISO 5893.
- Apply a defined loading/unloading cycle at a strain rate of 2.0 mm/min and record stress–strain curves.
- Calculate elasticity, lost work (hysteresis area between loading and unloading), and deformation work (area beneath the stress–strain curve) relative to control specimens.
- Reporting: Test report must include product identification, mixing and storage details, test equipment/calibration, results and interpretation of lost/deformation work, and any deviations from the procedure.
Applications and Who Uses It
EN 12637-1:2004 is used by:
- Manufacturers of polyurethane and elastic injection products to validate product durability and compatibility with concrete.
- Independent testing laboratories performing conformity and performance testing.
- Specifiers, consultants and structural repair contractors who need to select injection materials that remain flexible and durable in contact with concrete.
- Certification bodies and quality assurance teams assessing material fitness for repair and protection of concrete structures.
Practical applications include product selection for injection repair of cracks, quality control of batches, and generating data for technical datasheets and compliance documentation.

Die Norm EN 12637-1:2004 ist ein wesentlicher Bestandteil der Standards für Produkte und Systeme zum Schutz und zur Reparatur von Betonkonstruktionen. Sie legt die Prüfmethoden zur Bestimmung der Verträglichkeit von Injektionsprodukten, insbesondere Polyurethanen und anderen elastischen Injektionsprodukten, mit Beton fest. Dies ist von großer Bedeutung, da Injektionsprodukte oft alkaliempfindlich sind und deren Wechselwirkungen mit Beton wesentliche Auswirkungen auf die Haltbarkeit und die Integrität baulicher Maßnahmen haben können. Ein herausragendes Merkmal dieser Norm ist die detaillierte Beschreibung des Referenzverfahrens. Dieses Verfahren unterstützt Hersteller und Anwender dabei, die Eignung ihrer Produkte hinsichtlich der Wechselwirkungen mit Beton präzise zu bestimmen. Die Norm gewährleistet somit die Qualität und Zuverlässigkeit der verwendeten Injektionsstoffe, was wiederum zu einer Erhöhung der Langlebigkeit von Betonstrukturen beiträgt. Die Relevanz der EN 12637-1:2004 kann nicht hoch genug eingeschätzt werden, da sie eine Grundlage bietet, auf der sich sicherstellen lässt, dass die eingesetzten Materialien nicht nur durch physikalische Eigenschaften, sondern auch durch chemische Verträglichkeit überzeugen. Dies betrifft insbesondere den Bau- und Sanierungssektor, wo falsche Materialauswahl zu erheblichen Folgeschäden führen kann. Die Norm ist somit ein unverzichtbares Werkzeug für Bauingenieure, Architekten und Materialwissenschaftler, die an der Planung und Durchführung von Reparatur- oder Schutzmaßnahmen für Betonstrukturen beteiligt sind. Zusammenfassend lässt sich sagen, dass die EN 12637-1:2004 eine umfassende, klare und anwendbare Vorgehensweise bietet, um die Kompatibilität von Injektionsprodukten mit Beton zu überprüfen und damit einen wichtigen Beitrag zur Qualitätssicherung im Bereich der Betonsofortführung zu leisten.
La norme SIST EN 12637-1:2004 établit un cadre technique essentiel pour l'évaluation de la compatibilité des produits d'injection, notamment ceux à base de polyuréthane, avec les structures en béton. Son champ d'application se concentre sur les méthodes d'essai visant à déterminer la sensibilité de ces produits élastiques aux alcalins présents dans le béton, ce qui est crucial pour garantir l'intégrité des réparations effectuées sur des structures en béton. L'un des principaux atouts de cette norme réside dans sa méthode de référence bien définie, qui permet d'obtenir des résultats fiables et reproductibles. En se concentrant spécifiquement sur les produits d'injection finaux, elle évite toute ambiguïté quant à l'aaptabilité des matériaux utilisés dans divers contextes de réparation et de protection des structures en béton. La pertinence de la norme EN 12637-1:2004 est indéniable, surtout dans un environnement où la durabilité des infrastructures est primordiale. En fournissant des directives claires sur les tests de compatibilité, la norme facilite le choix des matériaux appropriés, minimisant ainsi les risques de défaillance des systèmes d'injection. Cela est particulièrement important dans l'industrie de la construction, où la performance à long terme des produits est essentielle pour la sécurité et la longévité des ouvrages en béton. Enfin, cette norme contribue également à la standardisation au sein de l'industrie, favorisant une approche homogène dans l'évaluation des produits d'injection. En intégrant les exigences de compatibilité, elle répond à un besoin croissant de fiabilité et de responsabilité dans les méthodes de réparation et de protection des structures en béton.
The EN 12637-1:2004 standard serves a critical role in assessing the compatibility of injection products, particularly polyurethane and other elastic injection materials, with concrete structures. Its focus on the interaction between injection products and concrete, especially concerning the alkalis found in concrete, reflects a comprehensive understanding of the material properties and their potential reactions. One of the significant strengths of this standard is its methodological approach, which establishes a clear and systematic reference procedure for testing compatibility. This ensures that manufacturers and practitioners can reliably determine whether their injection products will perform adequately when in contact with concrete, thereby safeguarding the integrity of concrete structures. The standard articulates protocols that are crucial for ensuring the longevity and durability of repairs in concrete, as incompatible products could lead to structural failures and costly remediation. Moreover, the relevance of EN 12637-1:2004 extends beyond mere compliance; it emphasizes the importance of quality and safety in applications involving injection products. By delineating compatibility parameters specifically for final injection products-notably excluding water-stopping foams-the standard offers tailored insights pertinent to professionals concerned with the repair processes of concrete structures. In an industry where the effectiveness and reliability of materials are paramount, the EN 12637-1:2004 standard stands out as a vital document that fosters consistency and high-quality outcomes in the protection and repair of concrete structures. The emphasis on rigorous testing of compatibility not only aids in product development but also instills confidence among end-users regarding the performance of injection products in various concrete applications.
