Overview - EN ISO 4589-1:2017 (Oxygen index test for plastics)
EN ISO 4589-1:2017 sets out the general requirements for measuring the burning behaviour of plastics by the oxygen index (OI) method. Part 1 defines scope, terminology and the principles that are applied in the companion test methods:
- ISO 4589-2 - ambient-temperature OI test (determines the minimum oxygen fraction at 23 °C ± 2 °C that just supports combustion);
- ISO 4589-3 - elevated-temperature OI test (determines OI over a range typically 25 °C–150 °C, up to 400 °C where required).
This standard establishes the test purpose, specimen types, basic apparatus concepts (transparent chimney with laminar O2/N2 flow), and general operating criteria used by the detailed parts.
Key topics and technical requirements
- Definitions and scope: introduces terms such as oxygen index (OI) and limiting oxygen index (LOI).
- Test principles: describes three common procedures-top-surface ignition, propagating-ignition, and thin-film-and the rationale for gas composition and flow control in a vertical chimney.
- Specimen preparation & conditioning: outlines that results depend on specimen size, shape and orientation and requires controlled conditioning before testing.
- Apparatus essentials: transparent column, sample holder, measuring device and laminar flow of oxygen/nitrogen mixtures.
- Operating conditions and controls:
- Calibration and gas-flow control are required.
- Flame application: maximum ~30 s with periodic removal every 5 s (to limit specimen overheating).
- Elevated-temperature routine: preheat in gas flow (240 s ± 10 s) to reach equilibrium before ignition (ISO 4589-3).
- Applicability & limitations: used for quality control and R&D; not sufficient alone for full fire-safety compliance or consumer-safety regulation.
Practical applications and users
- Who uses it: polymer and compound manufacturers, flame-retardant developers, cable and wire producers, test laboratories, and product R&D teams.
- Why use it:
- Routine quality control (e.g., verify flame-retardant loading).
- Material data sheets: supply LOI values for comparative use.
- R&D: study temperature-dependent changes in flammability and loss of additive efficacy (using ISO 4589-3).
- What it informs: relative flammability under controlled lab conditions and trends with temperature - useful for material selection and product development but not a full fire-hazard assessment by itself.

Introduction
[3]
The oxygen index (OI) test at ambient temperature was first described by Fenimore and Martin in
0[2]
1966. The first use of the method in standards was ASTM D2863: 197 and it has since been published
in a wide range of national and international standards. It was published as ISO 4589 in 1984 and has
now been revised as ISO 4589-2. The OI test at elevated temperatures is described in ISO 4589-3.
In the period since ASTM D2863 became a standard, a considerable number of papers have been
published about this test. An example is the review in Reference [6] relating to the relevance of the
test to real fire situations. Other papers have suggested empirical formulae relating OI to the amounts
of added fire retardant, or describe practical investigations on the equipment performance (see
Reference [7]). A clear consensus on the value of the two variants of the test has emerged, however, and
it is the purpose of this document to discuss the use of the equipment and the applicability of both test
methods.

The EN ISO 4589-1:2017 standard defines the general requirements for the oxygen index (OI) test, which is crucial for evaluating the burning behavior of plastics. This standard is particularly significant for industries focusing on fire safety and material performance, as it establishes a systematic approach to determining how materials react in the presence of oxygen. One of the key strengths of this standard is its clarity in specifying the conditions under which the OI test should be performed. By establishing a standard temperature range of 23 °C ± 2 °C for the introduction of the gas mixture, the standard ensures consistency and reliability in test results. This precision is essential for manufacturers and safety regulators who rely on these assessments to make informed decisions about material properties. Furthermore, the relevance of this standard is amplified by its complementary documents, ISO 4589‑2 and ISO 4589‑3. ISO 4589‑2 elaborates on the method for determining the minimum concentration of oxygen necessary to support combustion, providing a structured framework for testing. In contrast, ISO 4589‑3 extends the evaluation by exploring a broader temperature range, typically between 25 °C and 150 °C, and includes up to 400 °C, which is particularly relevant for applications where materials may be exposed to higher temperatures. The integration of these additional methods enhances the overall robustness of the EN ISO 4589-1:2017 standard, making it a comprehensive resource for professionals involved in materials testing and safety assessment. The focus on both general requirements and specific testing conditions underscores the document's role in promoting best practices in fire behavior assessment, ultimately contributing to improved safety standards in plastics applications. In summary, EN ISO 4589-1:2017 serves as a vital tool in the evaluation of burning behavior in plastics, with clear requirements and adaptable testing protocols that ensure its relevance across various industries. Its strengths lie in its meticulous detail and the seamless connection with additional ISO standards that collectively bolster material safety and performance assessments.
