General Information

Abstract

This standard specifies a method for assessing the poly(vinyl chloride) (PVC) content in reprocessable and recyclable unplasticized (PVC-U) materials or materials derived from PVC-U products. In this standard, only the method for calculation of the PVC content is described, while for the determination of the chlorine content reference is made to prEN ISO 1158:1997. If the material contains or is supposed to contain chlorinated poly(vinyl chloride) (PVC-C) or chlorinated polyethylene (PE-C), an apparent PVC content is calculated.

Overview

EN 1905:1998 is a CEN standard for plastics piping systems that defines a method to assess the poly(vinyl chloride) (PVC) content in reprocessable and recyclable unplasticized PVC (PVC‑U) materials or materials derived from PVC‑U products. The standard describes the calculation method for PVC content based on total chlorine content. The actual determination of chlorine is not defined in EN 1905 itself but is referenced to prEN ISO 1158:1997. When materials contain chlorinated PVC (PVC‑C) or chlorinated polyethylene (PE‑C), the result is reported as an apparent PVC content.

Key Topics

  • Scope and applicability
    • Assessment of PVC content in reprocessable/recyclable PVC‑U materials and derived products.
    • Applies to plastics piping systems: PVC‑U pipes, fittings and material.
  • Calculation method
    • Describes how to convert total chlorine content into a PVC content value.
    • Clarifies reporting of apparent PVC content when other chlorinated polymers are present.
  • Reference testing
    • Cross-references prEN ISO 1158:1997 for the analytical determination of total chlorine.
  • Material categories
    • Focuses on unplasticized PVC (PVC‑U); highlights limitations when chlorinated variants (PVC‑C, PE‑C) may skew results.
  • Reporting and interpretation
    • Specifies how results should be expressed and interpreted for material assessment and recycling decisions.

Applications

  • Manufacturers of PVC‑U pipes and fittings
    • Quality control to confirm PVC content in reprocessable streams and off‑spec material.
  • Recyclers and waste processors
    • Sorting and characterizing recycled PVC‑U feedstock to ensure consistent material quality.
  • Testing laboratories
    • Use the calculation method to report PVC content after measuring total chlorine.
  • Procurement and compliance teams
    • Verify material declarations, support conformity assessment and environmental reporting.
  • Regulators and standards bodies
    • Provide a harmonized approach for assessing recycled PVC content within plastics piping systems.

Related Standards

  • prEN ISO 1158:1997 - referenced method for determination of chlorine content (analytical measurement).
  • Other EN/ISO standards for PVC‑U piping and material testing provide complementary requirements for dimensions, mechanical properties and product conformity.

EN 1905:1998 is essential for stakeholders needing a standardized, chemistry‑based assessment of PVC content in PVC‑U piping materials, particularly where recycling, material verification and traceability are required.
