Full title and description

ISO 11345:2006 — Rubber — Assessment of carbon black and carbon black/silica dispersion — Rapid comparative methods. This International Standard specifies qualitative, rapid and comparative visual methods (using reference photographs) to assess the degree of macrodispersion of carbon black and carbon black/silica in compounded rubber, and a method to rate large agglomerates; results are expressed on numerical scales.

Abstract

ISO 11345:2006 defines qualitative visual methods for rapid comparative assessment of macrodispersion of carbon black and carbon black/silica in rubber. Ratings are made against a set of standard reference photographs and reported on a numerical scale from 1 to 10; an additional numerical scale (1 to 10) is provided for rating the presence of large agglomerates. The standard is intended for comparative and quality‑control purposes.

Scope

Specifies qualitative visual, rapid comparative methods to evaluate the degree of macrodispersion of carbon black and carbon black/silica in rubber compounds. The methods use a set of standard reference photographs for comparison; results are expressed on 1–10 numerical scales for dispersion and for large agglomerates. The procedures are intended for comparative assessment and quality control rather than absolute quantification.

Key topics and requirements

• Qualitative visual assessment procedures using calibrated reference photographs for comparison.
• Numerical rating scales (1–10) for macrodispersion of carbon black and carbon black/silica.
• Separate numerical rating method (1–10) for occurrence/size of large agglomerates.
• Intended use for rapid comparative checks and routine quality control in rubber compounding and production.
• References the relevant ISO technical committee (ISO/TC 45/SC 2) and normative context for rubber test methods.

Typical use and users

Used by rubber compounders, quality control laboratories, R&D teams in tire and rubber product manufacture, and test laboratories that perform routine checks on dispersion quality of carbon black and silica-filled rubber compounds. The method supports quick comparative ranking of batches and troubleshooting of mixing/dispersion processes.

Related standards

Relevant related documents include the previous edition ISO 11345:1997 (withdrawn and superseded by the 2006 edition), and other ISO test methods for rubber physical testing and specimen preparation such as ISO 23529 (general procedures for preparing and conditioning rubber test pieces) and ISO 4649 (abrasion testing methods) which sit in the same ICS area and are commonly used alongside dispersion assessments in rubber testing workflows.

FAQ

Q: What is this standard?

A: ISO 11345:2006 is an International Standard that specifies rapid qualitative visual methods for assessing the macrodispersion of carbon black and carbon black/silica in rubber, using reference photographs and numerical rating scales.

Q: What does it cover?

A: It covers procedures for visually comparing a test specimen against a set of standard reference photographs to assign dispersion ratings (1–10) and to rate large agglomerates (1–10). It is intended for comparative assessment and routine quality control rather than absolute quantification.

Q: Who typically uses it?

A: Rubber compounders, QC laboratories in tire and rubber product manufacturing, research and development laboratories, and third‑party testing bodies use this method to monitor dispersion quality and to support production troubleshooting.

Q: Is it current or superseded?

A: The 2006 edition (Edition 2) is published and was last reviewed and confirmed by ISO in 2024, so it remains current.

Q: Is it part of a series?

A: It forms part of the suite of ISO test methods and practices for rubber (work by ISO/TC 45/SC 2); related standards include specimen preparation and physical test methods such as ISO 23529 and other rubber testing standards (e.g., abrasion methods ISO 4649) commonly used in conjunction with dispersion assessment.

Q: What are the key keywords?

A: Rubber; carbon black dispersion; macrodispersion; silica; visual rating; reference photographs; rapid comparative methods; quality control.
