ISO 15877-2:2009/Amd 1:2010 PDF

Overview

ISO 15877-2:2009/Amd 1:2010 is an international amendment standard published by the International Organization for Standardization (ISO). This amendment applies to plastics piping systems for hot and cold water installations, specifically focusing on chlorinated poly(vinyl chloride) (PVC-C) pipes. It updates ISO 15877-2:2009, adding specifications for PVC-C Type I piping, particularly to accommodate requirements for low-temperature heating applications. The amendment was prepared by the European Committee for Standardization (CEN) and ISO Technical Committee TC 138 to reflect proven use of these systems across a variety of countries.

Key Topics

• PVC-C Pipe Applications: The amendment introduces enhanced specifications for PVC-C Type I pipes, supporting their safe and reliable use in hot and cold water installations, as well as low-temperature heating systems.
• Application Classes and Pressures: Adds new application class (Class 4 as per ISO 10508) and service conditions for 4 bar and 6 bar, which are relevant for low-temperature heating environments.
• Design Parameters:
  • Updates S-values (design coefficients) for various application classes and pressure ratings.
  • Specifies design stress values for PVC-C Type I pipes, ensuring appropriate performance characteristics under defined service conditions.
• International Harmonization: The amendment was developed collaboratively between ISO and CEN, ensuring alignment of European and international requirements.

Applications

ISO 15877-2:2009/Amd 1:2010 is highly relevant to manufacturers, designers, and installers of plastic piping systems deployed in:

• Residential and commercial hot and cold water systems
• Low-temperature heating installations (e.g., underfloor heating, wall heating systems)
• Retrofit and new builds, where proven, durable, and pressure-rated plastic pipes are required
• Markets where PVC-C piping systems are favored for their chemical resistance, ease of installation, and longevity

By integrating the updated application classes and stress values, industry professionals can ensure compliance, safety, and durability in water supply and heating system projects.

Related Standards

For comprehensive guidance and compliance, the following related standards are recommended:

• ISO 15877-1: Plastics piping systems for hot and cold water installations - PVC-C - Part 1: General
• ISO 10508: Plastics piping systems - Guidance for classification and design for service conditions
• ISO 13831: Plastics piping systems for water supply or drainage and sewerage under pressure - Chlorinated poly(vinyl chloride) (PVC-C)
• EN Standards (CEN TC 155): European standards for plastics pipes and ducting systems

Practical Value

Implementing the requirements from ISO 15877-2:2009/Amd 1:2010 helps organizations:

• Ensure product safety and reliability in hot and cold water and heating systems
• Meet international and European regulatory needs with harmonized technical specifications
• Optimize design and materials selection for cost-effectiveness and longevity
• Reduce risk of system failure, leaks, and non-compliance penalties
• Facilitate market access and interoperability through adherence to widely recognized standards

Leveraging this amendment ensures that water piping systems constructed with PVC-C meet consistently high standards for performance and durability, supporting both public safety and business objectives.
