Full title and description
ISO 2476:2014 — Butadiene rubber (BR) — Solution‑polymerized types — Evaluation procedures. This International Standard specifies the test materials, formulations, equipment, sample preparation and methods used to evaluate physical and chemical properties of solution‑polymerized butadiene rubbers (including oil‑extended types) and the vulcanization and tensile stress‑strain behaviour of vulcanized test mixes.
Abstract
ISO 2476:2014 defines physical and chemical tests on raw BR, standard test materials and formulations, processing and mixing conditions, procedures for evaluating vulcanization characteristics and methods for determining tensile stress‑strain properties of vulcanized mixes. It provides precision information and test report requirements to allow reproducible comparison of solution‑polymerized butadiene rubbers.

Scope
This standard applies to solution‑polymerized types of butadiene rubber (BR), including oil‑extended BR (OEBR). It covers sampling and preparative procedures for raw rubber, specified physical and chemical tests on raw rubbers, preparation and conditioning of standard test mixes, defined processing and vulcanization procedures for evaluation, and the determination and reporting of vulcanization characteristics and tensile stress‑strain properties of vulcanized test mixes.
Key topics and requirements
- Definitions and scope of solution‑polymerized BR and oil‑extended variants.
- Sampling and preparative procedures for raw rubber to obtain representative test portions.
- Specified physical and chemical tests on raw BR (to assess incoming material quality).
- Standard test materials and detailed test mix formulations for evaluation.
- Mixing, conditioning and vulcanization procedures for preparing reproducible test specimens.
- Methods for evaluating vulcanization characteristics (e.g., cure behaviour) and tensile stress‑strain of vulcanized mixes.
- Precision data and recommended contents for a test report to ensure comparability between laboratories.
These topics are set out to give repeatable, comparable evaluation results for production control, R&D and material acceptance.
Typical use and users
Primary users are rubber‑raw‑material producers, polymer manufacturers, rubber compounders, tire and rubber product R&D laboratories, independent testing laboratories and quality/acceptance teams. Typical uses include incoming material evaluation, batch acceptance, comparative material studies, compound development and verification of vulcanization behaviour under defined conditions.
Related standards
Normative and related references commonly associated with ISO 2476 include ISO 1795 (sampling and preparative procedures for raw rubber), ISO 23529 (general procedures for preparing and conditioning test pieces) and ISO 2393 (rubber test mixes — preparation, mixing and vulcanization — equipment and procedures). Other standards in the rubber test family (for tensile testing, vulcanization measurement and ageing tests) are typically used alongside ISO 2476.

FAQ
Q: What is this standard?
A: ISO 2476:2014 is an International Standard that defines evaluation procedures for solution‑polymerized butadiene rubbers (BR), specifying test mixes, preparation and test methods to assess raw rubber and vulcanized mix performance.
Q: What does it cover?
A: It covers sampling/preparative procedures for raw BR, required physical and chemical tests on raw rubber, standard test mix formulations, mixing and conditioning procedures, methods to evaluate vulcanization behaviour and tensile stress‑strain properties of vulcanized test mixes, plus precision and reporting requirements.
Q: Who typically uses it?
A: Rubber manufacturers, compounders, product R&D teams, independent test laboratories and quality/acceptance personnel use it for material evaluation, batch control, development and comparative testing.
Q: Is it current or superseded?
