Overview

EN ISO 14632:2021 - Extruded sheets of polyethylene (PE‑HD) - Requirements and test methods is a CEN-endorsed international standard that defines requirements and test methods for solid, flat extruded sheets made from polyethylene homopolymers (PE‑HD) without fillers or reinforcement. Applicable to sheet thicknesses from 0.5 mm to 40 mm, the standard also covers PE‑HD supplied in rolled form. Published in 2021, this edition supersedes earlier versions and aligns material designation with ISO 17855‑1.

Key topics and technical requirements

The standard specifies measurable quality attributes and standardized test procedures to verify them. Major technical topics include:

• Material scope: PE‑HD homopolymers only; additives such as processing aids, stabilizers, flame retardants and colorants are allowed, but compounds of unknown identity are prohibited.
• Appearance: Sheets must be substantially free from bubbles, voids, cracks, visible impurities and surface defects.
• Dimensional tolerances: Requirements for thickness, length and width, rectangularity, and bow (for rolled sheets).
• Mechanical and thermal properties: Defined properties include tensile stress at yield, tensile strain at yield, and modulus of elasticity in tension.
• Impact and flow properties: Charpy impact strength (notched) and melt mass‑flow rate (MFR) are specified.
• Density and shrinkage: Methods for determining density and shrinkage after heating are included.
• Test methods & conditioning: Guidance on specimen preparation, conditioning (per ISO 291), and referenced test standards (for example ISO 527, ISO 179, ISO 1133, ISO 1183, ISO 2818).

Applications and who uses the standard

EN ISO 14632:2021 is used where consistent material performance and traceable testing are required. Typical users include:

• Manufacturers and extruders of PE‑HD sheet for process control and product specifications.
• Quality control and testing laboratories implementing the referenced test methods.
• Procurement teams and specifiers who need objective acceptance criteria for sheet materials.
• Design and fabrication engineers working with PE‑HD in industrial panels, liners, signage, or thermoforming applications.
• Regulatory bodies and certification organizations requiring harmonized test procedures.

Related standards

EN ISO 14632:2021 references and works alongside other ISO standards such as:

• ISO 17855‑1 (designation system for PE materials)
• ISO 527 (tensile properties)
• ISO 179 (Charpy impact)
• ISO 1133 (MFR/MVR)
• ISO 1183 (density)
• ISO 291 (conditioning)

EN ISO 14632:2021 provides a concise, standardized basis for assessing PE‑HD extruded sheet quality and conformity - essential for reliable sourcing, testing, and specification of extruded polyethylene sheets.

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.
