Overview

ISO 1431-3:2017 specifies reference and alternative methods for determining ozone concentration in laboratory test chambers used for assessing the resistance of vulcanized or thermoplastic rubber to ozone cracking. It defines a UV absorption reference method and alternative instrumental and wet‑chemical techniques, including calibration and reporting requirements. The document is part of the ISO 1431 series on rubber resistance to ozone cracking.

Key technical topics and requirements

Reference method (Method A - UV absorption)

Adopted as the calibration reference for other methods.
Carried out in accordance with ISO 13964 (air quality - ultraviolet photometric method).

Alternative instrumental methods (Method B)

B1 - Electrochemical: coulometric cell with buffered KI solution; current proportional to ozone concentration.
B2 - Chemiluminescence: reaction of ozone with ethylene producing measurable light.

Wet‑chemical methods (Method C)

Procedures I, II and III (annexed normative descriptions) based on ozone absorption and titration techniques.

Calibration and procedure

All apparatus must be calibrated against the UV absorption method (ISO 13964).
Instrument setup, zeroing and routine checks are required for reliable measurements.

Expression of results

Ozone concentration usually expressed in parts per hundred million by volume (pphm); alternatives include mg/m³ or mPa (partial pressure of O3).
ISO 1431-3 provides conversion guidance and notes that at 1 013 hPa and 273 K, 1 pphm ≈ 1.01 mPa.

Influence of atmospheric pressure

Annex A (informative) explains how ambient pressure affects cracking rates and recommends expressing concentration as partial pressure or correcting volumetric values.

Safety

Ozone is highly toxic; the standard highlights recommended exposure control and ventilation (an absolute maximum of 10 pphm is suggested unless national rules are stricter).

Practical applications and users

Test laboratories performing ozone cracking resistance tests on rubber products.

Rubber manufacturers and quality control teams validating materials for outdoor or ozone-prone applications (hoses, seals, tyres, gaskets).

R&D groups comparing sensor technologies (UV, electrochemical, chemiluminescence, wet chemistry).

Standards bodies and accreditation organizations verifying measurement traceability and calibration procedures.
