Overview
ISO 19846:2017 defines a standardized coding and numeric classification system for reclaimed rubber, covering reclaimed natural rubber and reclaimed isobutylene‑isoprene (IIR) rubber. The standard enables consistent identification of reclaimed rubber grades by specifying code elements based on measured properties. Classification relies on test results determined in accordance with ISO/TS 16095 (natural rubber) or ISO/TS 16096 (reclaimed IIR).
Key topics and technical requirements
- Scope: Coding system for reclaimed natural rubber and reclaimed IIR; numeric classes to communicate quality ranges.
- Measured parameters used for classification:
- Mooney viscosity (ML(1+4) at 100 °C) - coded MVA, MVB, MVC, MVD, MVE, MVF with defined MV ranges.
- Tensile strength (MPa) - coded TA, TB, TC, TD, TE with specified TS ranges.
- Rubber hydrocarbon content (%) - coded RH1, RH2, RH3, RH4 with defined RHC thresholds.
- Acetone extract (%) - coded AE1, AE2, AE3, AE4 with AE ranges.
- Classification output: A compound code that begins with a type identifier (1 = reclaimed natural rubber, 2 = reclaimed IIR) followed by the four property codes. Example designations from the standard:
- 1 MVC TC RH2 AE2
- 2 MVB TC RH2 AE1
- Testing references: Property values used for coding must be determined per ISO/TS 16095 or ISO/TS 16096; ISO 19846 contains no additional normative references.
Applications and practical value
- Procurement and specification: Enables buyers and suppliers to unambiguously specify reclaimed rubber grades for compound formulations and manufacturing.
- Quality control and traceability: Standardized codes help quality labs and production teams track incoming reclaimed material and match it to expected performance.
- Material selection: Compounders and R&D teams can quickly compare reclaimed rubber lots by Mooney viscosity, tensile strength, hydrocarbon content and extractables, simplifying blend design and process adjustments.
- Recycling and circular economy: Facilitates consistent reuse of reclaimed rubber in downstream products by creating a common language for reclaimed material quality.
Who should use this standard
- Reclaimed rubber suppliers and recyclers
- Rubber compounders and manufacturers (including automotive, industrial and consumer rubber products)
- Quality assurance and testing laboratories
- Procurement specialists and material engineers seeking consistent reclaimed-rubber specifications

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
