General Information
- Abstract
1.1 This document establishes a system of designation for plasticized PVC thermoplastic material which can be used as the basis for specifications.
1.2 The types of PVC-U plastics are differentiated from each other by a classification system based on appropriate levels of the designatory properties
a) Shore hardness,
b) density,
c) torsional-stiffness temperature at 300 MPa,
and on information about physical form, intended application and/or method of processing, important properties, additives, colorants.
1.3 This document is applicable to all plasticized compositions of homopolymers and copolymers that contain at least a mass percentage of 50 % of vinyl chloride. It is also applicable to plasticized compositions containing chlorinated poly (vinyl chloride) and to plasticized compositions containing blends of one or more of the above-mentioned polymers, provided that the total amount of these polymers represents at least a mass percentage of 50 % of the polymer content of the composition.
This document applies to materials ready for normal use in the form of powder (dry blends), granules or pellets and to materials unmodified or modified by colorants, additives, fillers, etc. It does not apply to cellular plastics or to paste compositions (plastisols).
1.4 This document does not intend to imply that materials having the same designation give the same performance. It does not provide engineering data, performance data or data on processing conditions which might be required to specify a material for a particular application and/or method of processing.
If additional properties are required, they are, if suitable, determined using the test methods specified in ISO 24023-2.
1.5 In order to specify a thermoplastic material for a particular application or to ensure reproducible processing, additional requirements can be given in data block 5 (see 4.1).

Overview
EN ISO 24023-1:2020 - Plastics - Plasticized poly(vinyl chloride) (PVC‑P) moulding and extrusion materials - Part 1: Designation system and basis for specifications - establishes a standardized designation system for plasticized PVC thermoplastic materials. The standard provides the coding framework (identity and individual‑item blocks) that can be used as the basis for material specifications, enabling clear identification of PVC‑P grades for moulding and extrusion. It applies to plasticized homopolymers, copolymers and blends that contain at least 50% vinyl chloride by mass, supplied as powders (dry blends), granules or pellets. Cellular plastics and paste compositions (plastisols) are excluded.
Key Topics
- Designation system structure: standardized pattern comprising an identity block (e.g., symbol PVC‑P) and an individual‑item block subdivided into five data blocks.
- Data block 1: Identification symbol - PVC‑P (per ISO 1043‑1).
- Data block 2: Fillers/reinforcements and nominal content (not detailed in this part).
- Data block 3: Intended application or processing method (position 1) and important properties/additives/colour (positions 2–8). Uses code letters (examples: B = Blow moulding, E = Extrusion, M = Injection moulding, T = Tape manufacture, N = Natural (no colour)).
- Data block 4: Designatory properties - coded values for Shore hardness (2‑figure code), density (2‑figure code), and torsional‑stiffness temperature at 300 MPa (2‑figure code), separated by hyphens.
- Data block 5: Optional additional requirements for alternative specifications or reproducible processing.
- Scope limits and applicability: covers plasticized PVC compositions ≥50% vinyl chloride; includes chlorinated PVC and specified blends; excludes cellular and plastisol forms.
- Clarification of intent: the standard provides designation and a basis for specification but does not supply engineering performance data or processing conditions. Additional properties, if required, are to be determined using ISO 24023‑2 test methods.
Applications and Who Uses It
- Material and compound manufacturers: to label and communicate PVC‑P grade identity and key designatory properties.
- Product designers and OEMs: to select appropriate PVC‑P grade descriptors for moulding and extrusion applications.
- Procurement and quality assurance teams: to create unambiguous purchase specifications and acceptance criteria.
- Test laboratories and conformity assessors: to interpret designation codes and reference ISO 24023‑2 for property testing.
- Standards bodies and regulatory organizations: to harmonize terminology and material classification across markets.
Practical benefits include improved material traceability, consistent supplier‑buyer communication, and a common basis for specifying PVC‑P for extrusion, injection moulding and related processing.
Related Standards
- ISO 1043‑1 - Symbols and abbreviated terms (basic polymers) - referenced for the PVC‑P symbol.
- ISO 24023‑2 - Preparation of test specimens and determination of properties - for test methods when extra properties are required.
- Supersedes earlier editions (ISO 2898‑1 series).
Keywords: EN ISO 24023‑1:2020, PVC‑P designation system, plasticized poly(vinyl chloride), thermoplastic materials, Shore hardness, density, torsional‑stiffness temperature, material specification.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
