Overview

EN ISO 9054:1999 is an international standard developed by CEN that specifies test methods for rigid cellular plastics, particularly self-skinned, high-density materials. These materials commonly have an overall density exceeding 100 kg/m³ and feature an integral surface skin formed during manufacturing. The standard outlines fundamental procedures for determining the physical properties of such cellular plastics, ensuring consistent evaluation and comparison between materials.

This standard is essential for manufacturers, suppliers, and purchasers dealing with high-density integral-skin foams and structural foams. It encourages the use of standardized test specimen thickness and permits method adaptation for products of varying thickness by mutual agreement.

Key Topics

• Scope and Application
  Defines test procedures applicable to rigid, self-skinned cellular plastics, including materials with one or more surface zones of higher density or relatively uniform density.

• Test Specimen Preparation
  Guidelines for specimen dimensions, conditioning, and machining to preserve material integrity. Specimens must retain the skin and be cut a minimum distance from edges, with conditioning typically at 23°C and 50% relative humidity.

• Physical Property Tests
  Detailed methods for measuring key material properties:

  • Apparent Density (ISO 845)
  • Bending Strength (ISO 178)
  • Impact Strength via falling dart test (ISO 6603-1 and ISO 6603-2)
  • Tensile Properties (ISO 1926)
  • Shear Strength (ISO 1922)
  • Surface Hardness (ISO 868)
  • Thermal Conductance (ISO 8301/ISO 8302)
  • Burning Behaviour (national standards)
  • Dielectric Strength (IEC 243)
  • Linear Thermal Expansion (ISO 4897)
  • Deflection Under Load with Increasing Temperature (ISO 75)
  • Screw Retention (Annex A - detailed screw withdrawal test procedures).

• Conditioning and Testing Protocols
  Ensures consistent environmental conditions prior to testing, such as time, temperature, and humidity, adapted if necessary for tropical climates or specific agreements.

• Test Reporting Requirements
  Specifies thorough documentation, including standard references, material and sample details, manufacturing process, specimen dimensions, conditioning parameters, test conditions, results with statistical data, deviations, and observations.

Applications

EN ISO 9054:1999 is critical for quality control and product development in sectors using rigid self-skinned cellular plastics, such as:

• Automotive Industry
  For evaluating integral skin foams used in seating, insulation, and structural components.

• Construction Materials
  Assessing physical and thermal performance of rigid foam panels and insulation materials.

• Furniture Manufacturing
  Testing durability, hardness, and screw retention of foam cushions and components.

• Electrical and Electronics
  Ensuring dielectric strength and thermal stability of insulating foams.

• Packaging Industry
  Determining impact resistance and mechanical properties for protective high-density foams.

The standard’s comprehensive test methods enable consistent material characterization, facilitating supplier-purchaser agreements and assuring product conformity to application requirements.

Related Standards

EN ISO 9054:1999 references and integrates related international standards to cover diverse mechanical and thermal properties:

• ISO 845 – Determination of apparent (bulk) density of cellular plastics
• ISO 178 – Flexural properties of rigid plastics
• ISO 6603-1 & ISO 6603-2 – Multi-axial impact behavior and falling dart test methods
• ISO 1922, 1923, 1926 – Shear strength, dimensional measurement, and tensile test methods for cellular plastics
• ISO 868 – Surface hardness by durometer (Shore hardness)
• ISO 8301, 8302 – Thermal conductivity and resistance determination
• ISO 4897 – Linear thermal expansion of rigid materials
• ISO 75 – Deflection under load with temperature increase
• IEC 243 – Dielectric strength of solid insulating materials

By combining these well-established standards, EN ISO 9054 ensures a robust, harmonized approach for evaluating high-density self-skinned cellular plastics for industrial and commercial use.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Interna-
tional Standard requires approval by at least 75 % of the member bodies
casting a vote.
International Standard IS0 9054 was prepared by Technical Committee
ISO/TC 61, Plastics.
