Plastics piping systems - Unplasticized poly(vinyl chloride) (PVC-U) pipes, fittings and material - Method for assessment of the PVC content based on total chlorine content
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.
Kunststoff- Rohrleitungssysteme - Rohre, Formstücke und Werkstoff aus weichmacherfreiem Polyvinylchlorid (PVC-U) - Verfahren zur Bestimmung des PVC-Gehaltes auf der Basis des Gesamtchlorgehaltes
Diese Norm legt ein Verfahren zur Bestimmung des Polyvinylchlorid (PVC)- Gehaltes in Rücklaufmaterial oder Recyklat aus weichmacherfreiem Polyvinylchlorid (PVC-U) oder Produkten aus PVC-U fest. In dieser Norm wird nur das Verfahren zur Berechnung des PVC-Gehaltes beschrieben. Zur Bestimmung des Chlorgehaltes wird auf prEN ISO 1158:1997 verwiesen. Wenn der Werkstoff chloriertes Polyvinylchlorid (PVC-C) oder chloriertes Polyethylen (PE-C) enthält oder dies vermutet wird, wird der scheinbare PVC-C-Gehalt berechnet.
Systèmes de canalisations en plastique - Tubes, raccords et matières en poly(chlorure de vinyle) non plastifié (PVC-U) - Méthode d'évaluation de la teneur en PVC sur la base de la teneur totale en chlore
La présente norme spécifie une méthode pour le dosage du polychlorure de vinyle (PVC) dans les matières non plastifiées (PVC-U) remises en oeuvre ou recyclables ou dans les matières provenant de produits en PVC-U. Dans la présente norme, seule la méthode pour le calcul de la teneur en PVC est détaillée; pour la détermination de la teneur en chlore, il est fait référence à prEN ISO 1158:1997. Si la matière contient ou est supposée contenir du polychlorure de vinyle chloré (PVC-C) ou du polyéthylène chloré (PE-C) la teneur apparente en PVC est calculée.

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.
