EN ISO 15877-3:2009/A1:2010 PDF

Overview

EN ISO 15877-3:2009/A1:2010 is an amendment standard under the EN ISO 15877 series, focusing on plastics piping systems for hot and cold water installations made from chlorinated poly(vinyl chloride) (PVC-C). This amendment specifically addresses fittings used in PVC-C piping systems, updating requirements and testing protocols to enhance safety, reliability, and performance.

Developed collaboratively by the European Committee for Standardization (CEN) and the International Organization for Standardization (ISO), this standard is a key reference for manufacturers, engineers, and installers engaged in plumbing and water supply systems. It aligns with ISO/TC 138 and CEN/TC 155, technical committees specialized in plastics piping and fittings.

Key Topics

• Scope of Amendment 1 This amendment introduces Class 4 fittings as defined by ISO 10508 to address low-temperature heating applications commonly found in some countries. It modifies testing requirements and material stress limits to ensure robustness for operating pressures of 4 and 6 bars.

• Material Specifications Focuses on chlorinated poly(vinyl chloride) (PVC-C) Type I materials suitable for hot and cold water installations, ensuring compatibility with operational temperature ranges and mechanical loads.

• Testing Requirements Provides updated hydrostatic test pressures based on design class (Class 1, 2, and 4), temperature, and test duration. For example:

  • Maximum design temperatures up to 80 °C for Classes 1 and 2, 70 °C for Class 4.
  • Design stresses and hydrostatic stresses specified in MPa, adjusted for testing conditions at 20 °C, 60 °C, and 80 °C.
  • Test pressures calibrated for design pressures of 4, 6, 8, and 10 bars depending on class and test temperature.

• Compliance and Regulatory Alignment Mandates adherence to CEN/CENELEC internal regulations for integration into national standards without alterations, supporting uniformity across European markets.

• Multilingual Documentation & Accessibility Published in official CEN languages (English, French, German) with valid translations maintaining equal status, facilitating broad adoption.

Applications

• Hot and Cold Water Installations Enables safe and efficient piping solutions for domestic and commercial water supply systems, catering to both cold and heated water distribution.

• Low-Temperature Heating Systems Introduces suitable fittings for PVC-C piping in heating installations operating at moderate temperatures and pressures, extending the material's application scope.

• Building and Infrastructure Projects Ensures fittings meet stringent safety and performance standards for municipal, residential, and industrial water systems, minimizing leakage and maximizing durability.

• Manufacturing and Quality Assurance Provides clear testing protocols for manufacturers to validate hydrostatic resistance and material integrity of PVC-C fittings, ensuring products meet international quality benchmarks.

Related Standards

• ISO 15877-1 and ISO 15877-2 Cover general requirements and pipes respectively for PVC-C piping systems, complementing Part 3 which focuses on fittings.

• ISO 10508 Defines material classes, including the Class 4 referenced in this amendment for low-temperature heating applications.

• EN ISO 15877 Series Comprehensive guidance on design, performance, and testing of PVC-C plastic piping systems for water installations.

• CEN/CENELEC Internal Regulations Provide framework for standard harmonization in Europe, ensuring this amendment becomes part of nationally adopted standards.
