ISO 15877-3:2009/Amd 1:2010

Overview

ISO 15877-3:2009/Amd 1:2010 is an amendment to the international standard concerning plastics piping systems using chlorinated poly(vinyl chloride) (PVC-C) for hot and cold water installations. This amendment, issued in 2010, updates Part 3 of ISO 15877-3, which focuses specifically on the requirements for fittings used in PVC-C piping systems. These systems are widely employed in plumbing applications due to their durability, corrosion resistance, and suitability for both hot and cold water supply.

The amendment integrates updated classifications and testing criteria, reflecting practical experience and technical advancements in PVC-C piping components. It aligns with the collaborative standards development efforts of ISO and the European Committee for Standardization (CEN), ensuring global compatibility and reliability in plumbing infrastructure.

Key Topics

• Scope of PVC-C Fittings: Specifies requirements for fittings made from PVC-C Type I, used primarily in hot and cold water piping systems, including applications involving low-temperature heating.

• Application Classes: Introduction of Application Class 4, based on ISO 10508, to cover operational conditions requiring service pressures of 4 bar and 6 bar, commonly encountered in various international installations.

• Material and Design Criteria: Defines design stresses and material strengths, focusing on ensuring long-term hydrostatic performance under specified temperature and pressure regimes.

• Test Methods and Conditions:

  • Hydrostatic pressure testing tailored for PVC-C fittings, including short-term and long-term tests.
  • Test temperatures and durations updated for accuracy and consistency.
  • Revised test pressure values reflecting safety margins for different application classes.

• Pressure Ratings and Temperature Limits:

  • Maximum service temperatures specified for each application class.
  • Testing pressures calibrated to validate performance under defined service conditions, enhancing reliability and safety in installation.

• Collaborative Standard Development: Reflects cooperation between ISO technical committee ISO/TC 138 and the European Technical Committee CEN/TC 155, emphasizing harmonization of European and international standards.

Applications

ISO 15877-3:2009/Amd 1:2010 is highly relevant for:

• Plumbing and Water Distribution Systems: Design and manufacturing of fittings for hot and cold potable water systems in residential, commercial, and industrial buildings.
• Heating Installations: Low-temperature heating systems employing PVC-C piping, benefiting from the inclusion of Class 4 service conditions.
• Water Supply Infrastructure: Municipal and private water supply networks requiring durable, corrosion-resistant piping components.
• Building Code Compliance: Ensuring that fittings meet internationally recognized performance and safety criteria to satisfy regulatory requirements.
• Manufacturing and Quality Control: Guiding producers in testing protocols and design specifications to maintain consistency and safety in PVC-C fitting products.

Related Standards

• ISO 15877 Series: Encompasses specifications for PVC-C piping systems, including pipes (Part 2) and joints (Part 4).
• ISO 10508: Defines application classes and service conditions for thermoplastics piping systems, referenced within this amendment for Class 4 criteria.
• EN 1452 Series (European Standard): Addresses PVC piping systems for water supply, which aligns closely with ISO 15877 standards.
• ISO 13831: Concerned with pressure testing methods for plastic piping, supporting the test procedures outlined in this amendment.

Adopting ISO 15877-3:2009/Amd 1:2010 enhances the integrity, safety, and longevity of plastics piping systems used worldwide for potable water distribution, enabling manufacturers and engineers to deliver compliant, high-quality PVC-C fittings suitable for a wide range of water installation applications.
