Overview
EN ISO 12236:2006 - "Geosynthetics - Static puncture test (CBR test)" specifies a standardized laboratory method to determine the puncture resistance of geosynthetics by measuring the force required to push a flat‑ended plunger through a specimen. The procedure (commonly called the CBR push‑through test) is intended for most geosynthetic products (geotextiles, geomembranes, geocomposites) except materials with apertures greater than 10 mm. Tests are normally performed on dry specimens conditioned to the standard atmosphere.
Key topics and technical requirements
- Test principle: Measure plunger force while a flat, stainless‑steel plunger is advanced centrally through a clamped specimen at a constant displacement rate. Record push‑through force and displacement and plot force‑displacement curves.
- Specimen quantity: Five specimens taken at random (ISO 9862 sampling).
- Conditioning: Standard atmosphere (20 ± 2 °C, 65 ± 5 % RH) per ISO 554; specimens considered conditioned when mass change ≤ 0.25 % between weighings.
- Apparatus & dimensions:
- Plunger: stainless steel, diameter (50 ± 0.5) mm; leading edge radius (2.5 ± 0.2) mm.
- Clamping rings: internal diameter (150 ± 0.5) mm; serrated/gripping surfaces to prevent slippage.
- Testing machine: compliant with ISO 7500‑1 (class 1 or 0) and capable of a constant displacement rate of (50 ± 5) mm/min with force/displacement recording.
- Measured quantities & reporting:
- Push‑through force (Fp) in kilonewtons (3 significant figures).
- Push‑through displacement (hp) in millimetres (±1 mm), force‑displacement graph if required.
- Calculate mean push‑through force and coefficient of variation (%) for the data set.
- Test report must cite standard reference (ISO 12236:2006), sample identification (ISO 10320), conditioning details, results, any slippage/cutting evidence, and deviations.
Applications - who uses this standard
- Manufacturers: product development and quality control for geotextiles, geomembranes, and geosynthetic composites.
- Independent test laboratories: conformance testing and certification.
- Specifiers / engineers: performance specification for civil engineering projects (roads, embankments, landfill liners, erosion control) where concentrated or localized puncture resistance is required.
- Procurement & acceptance testing: verifying delivered materials meet puncture resistance requirements.
Keywords: geosynthetics, static puncture test, CBR test, ISO 12236, puncture resistance, push‑through force, geotextiles, testing standard.

SIST EN ISO 12236:2007は、地盤工学や土木工事において重要な役割を果たす地盤用合成材料（ジオシンセティクス）の静的貫通試験（CBR試験）に関する国際規格であるEN ISO 12236:2006を基にしています。この標準は、平坦な先端のプランジャーを用いて、ジオシンセティクスを貫通させるのに必要な力を測定することで、その貫通抵抗を評価する方法を定義しています。 この標準の範囲は、指定された雰囲気で条件付けされた乾燥試料に対して通常実施され、ほとんどの種類のジオシンセティクス製品に適用可能です。ただし、開口部が10mmを超える材料には適用されない点に注意が必要です。このような明確な適用範囲は、ユーザーが試験の実施条件を理解し、適正な材料選定を行う上で非常に重要です。 EN ISO 12236:2006の強みは、その試験方法が広く適用可能であることです。さまざまなジオシンセティクス製品に対応しているため、建設業界における材料の選定や品質管理に貢献しています。また、試験は比較的シンプルで、実施が容易なため、現場での迅速な判断を助けることができます。 さらに、この標準は、地盤工学における実用的な応用にも密接に関連しており、ジオシンセティクスの性能評価における信頼性を高めます。そのため、EN ISO 12236:2006は、土木工事の設計や施工における品質保証プロセスにおいて重要なツールとなっています。
EN ISO 12236:2006 표준은 지오합성재료의 정적 천공 저항을 측정하기 위해 고안된 테스트 방법을 명시하고 있습니다. 이 표준은 평탄한 끝이 있는 플런저를 통해 지오합성재료를 관통하는 데 필요한 힘을 측정하는 과정을 설명합니다. 특히, 이 테스트는 규정된 대기에서 조절된 건조 샘플에 대해 수행됩니다. EN ISO 12236:2006은 다양한 종류의 지오합성재료에 적용될 수 있지만, 개구가 10 mm를 초과하는 재료에는 적용되지 않는 점이 특징입니다. 이러한 범위는 표준의 적정성과 활용성을 높이며, 특히 지오합성재료의 내구성과 안전성을 중요시하는 건설 및 환경 분야에서의 응용 가능성을 확대합니다. 이 표준의 강점은 실용적이고 정확한 테스트 방법을 제공하여 다양한 지오합성재료의 품질 평가를 용이하게 한다는 점입니다. 더불어, 표준에 따라 테스트를 수행하는 것은 재료의 천공 저항성을 명확히 이해하고 개선하는 데 기여하며, 이를 통해 제품의 신뢰성을 높이는 데 중요한 역할을 합니다. 따라서 EN ISO 12236:2006은 지오합성재료 관련 산업에서 필수적인 기준으로 자리 잡고 있습니다.
La norme EN ISO 12236:2006 offre une méthodologie précise pour évaluer la résistance à la perforation des géosynthétiques à l'aide d'un test standardisé, souvent dénommé test CBR. En définissant comment mesurer la force nécessaire pour enfoncer un poussoir à bout plat à travers divers géosynthétiques, cette norme établit des critères clairs et reproductibles qui garantissent la fiabilité des résultats. L'étendue de cette norme est particulièrement pertinente, car elle s'applique à une grande variété de produits géosynthétiques, fournissant ainsi une base solide pour comparer leurs performances. Toutefois, il est important de noter que la norme exclut les matériaux ayant des ouvertures supérieures à 10 mm, ce qui pourrait limiter son application dans certains cas spécifiques. Parmi les forces notables de la norme EN ISO 12236:2006, on trouve son approche méthodologique rigoureuse et la possibilité d'effectuer des essais sur des échantillons conditionnés dans un environnement contrôlé. Cette condition de sécheresse permet d'obtenir des résultats précis et représentatifs, essentiels pour le développement et l'usage de matériaux géosynthétiques dans des applications variées. En somme, la norme SIST EN ISO 12236:2007 est un document fondamental pour les professionnels de l'industrie des géosynthétiques, car elle garantit non seulement la performance et la durabilité des matériaux testés, mais aussi leur conformité aux standards internationaux de qualité. Sa pertinence dans le domaine des géosynthétiques ne saurait être sous-estimée, et son adoption contribue à améliorer la sécurité et la fiabilité dans des projets d'ingénierie et de construction.
Die Norm EN ISO 12236:2006 legt klare Parameter für die Durchführung von statischen Durchstoßprüfungen an Geokunststoffen fest. Diese Norm ist besonders relevant für die Bestimmung der Durchstoßfestigkeit, indem die Kraft gemessen wird, die erforderlich ist, um einen flachen Kolben durch die Geokunststoffe zu drücken. Der Anwendungsbereich dieser Norm umfasst die meisten Produktarten von Geokunststoffen, jedoch mit der Einschränkung, dass sie nicht für Materialien mit Öffnungen größer als 10 mm anzuwenden ist. Ein herausragendes Merkmal dieser Norm ist die präzise Methode zur Bewertung der mechanischen Robustheit von Geokunststoffen, die für unterschiedliche Bau- und Ingenieurprojekte von entscheidender Bedeutung ist. Die Durchführung des Tests unter festgelegten Bedingungen garantiert eine Konsistenz in den Ergebnissen und ermöglicht eine vergleichbare Bewertung der Produkte von verschiedenen Herstellern. Die Norm ist auch von großer Bedeutung für die Qualitätssicherung in der Geotechnik, da sie den Anwendern hilft, die Eignung von Geokunststoffen für spezifische Anwendungen zu bewerten, indem sie eine zuverlässige Methode zur Messung der Durchstoßfestigkeit bietet. Darüber hinaus unterstützt sie die Hersteller dabei, ihre Produkte zu optimieren und den Sicherheitsstandards zu entsprechen. Insgesamt bietet die EN ISO 12236:2006 eine fundierte Grundlage für die Bewertung der physikalischen Eigenschaften von Geokunststoffen durch einen standardisierten statischen Durchstoßtest und ist somit ein unverzichtbares Werkzeug in der Materialprüfung und -entwicklung in der Geotechnik.
The standard EN ISO 12236:2006 provides a comprehensive methodology for assessing the static puncture resistance of geosynthetics through the CBR test. This document specifies the procedure to measure the force necessary to penetrate a flat-ended plunger into various geosynthetic materials, highlighting its scope in ensuring the reliability of geosynthetic products used in various applications. One of the significant strengths of this standard is its applicability to a wide range of geosynthetic products, allowing for consistent quality assurance across different materials, although it does not accommodate those with apertures greater than 10 mm. This limitation ensures that the focus remains on materials that can be more rigorously tested, thereby facilitating accurate and relevant results. Furthermore, the standard emphasizes the importance of conditioning the specimens in a designated atmosphere before testing, which enhances the repeatability and reliability of the puncture resistance results. This aspect of the procedure underscores the standard's commitment to high testing standards and accuracy, making it an essential tool for manufacturers and engineers involved in the design and production of geosynthetics. In summary, EN ISO 12236:2006 serves as a vital benchmark in the geosynthetic industry. Its clear methodology for static puncture testing not only ensures the quality of materials but also supports manufacturers in adhering to best practices, ultimately contributing to enhanced performance and safety in their applications.
