Overview
SIST EN ISO 13264:2018 defines a standardized test method for evaluating the mechanical strength or flexibility of fabricated thermoplastic fittings intended for non-pressure underground drainage and sewerage piping systems. Developed by CEN and based on ISO 13264:2010, this standard ensures that thermoplastic fittings used in gravity-flow drainage and sewerage systems meet rigorous requirements for structural integrity and serviceability in underground, non-pressure environments.
These tests are essential for manufacturers, laboratories, and quality assessors to verify that fabricated fittings can withstand typical installation and operational stresses without failure, splitting, or leakage. The methodology supports both product development and ongoing compliance for market access within the European Union and globally.
Key Topics
- Scope and Purpose: The standard specifies procedures to test the mechanical strength or flexibility of fabricated thermoplastic fittings for non-pressure, underground drainage and sewerage applications.
- Applicable Fittings: Includes thermoplastics fittings designed for gravity-based (non-pressure) sewerage and drainage systems installed below ground level.
- Test Principle: Involves subjecting the fitting, assembled with appropriate piping, to a bending moment or displacement at the critical point most likely to experience structural damage. The process determines if the fitting can resist failure under simulated conditions.
- Sample Preparation: Requires specific conditioning (temperature and time) and the use of pipes corresponding to the intended application, ensuring results are relevant and reproducible.
- Testing Procedure:
- Application of force to either reach a specified moment or displacement.
- Observation for any visible signs of failure such as splitting, cracking, separation, or leakage.
- Both mechanical jointed and non-mechanical (cemented or fused) fittings are covered.
- Reporting Requirements: Clear documentation, including reference to the standard, product identification, test conditions, results, and observations, must be provided for conformity assessment.
Applications
SIST EN ISO 13264:2018 is highly relevant in several practical contexts:
- Product Certification: Serves as a benchmark for certifying the structural performance of fabricated thermoplastics fittings used in underground drainage and sewerage piping systems.
- Quality Control and Assurance: Applied by manufacturers and assessment bodies to ensure the consistency and durability of thermoplastic fittings before they enter the supply chain.
- Project Specification and Tendering: Cited in technical specifications for construction projects involving underground non-pressure drainage and sewerage, ensuring only compliant fittings are used.
- Research and Development: Assists in comparing new materials or fabrication techniques in the development of innovative drainage and sewerage system components.
- Regulatory Compliance: Supports fulfillment of national and international requirements for underground plastics pipeline products, facilitating access to procurement markets within EU member states and beyond.
Related Standards
To ensure a comprehensive approach to plastics piping system quality and safety, SIST EN ISO 13264:2018 is often referenced alongside other standards, such as:
- EN 12256: Superseded by SIST EN ISO 13264:2018, previously addressed similar testing requirements for mechanical strength of thermoplastics fittings.
- EN ISO 13263: Specifies similar testing for complete piping systems, including additional requirements for pipes.
- EN ISO 1452: Addresses specifications for piping systems made from unplasticized polyvinyl chloride (PVC-U).
- EN 1401: Covers plastics piping systems for non-pressure underground sewerage and drainage made from PVC-U.
- EN 13476: Standards for structured-wall piping systems and fittings for non-pressure underground drainage and sewerage.
By adhering to SIST EN ISO 13264:2018, stakeholders can ensure that fabricated thermoplastics fittings for underground non-pressure drainage and sewerage installations are tested for mechanical strength and flexibility, leading to safer and more durable infrastructure.
