ISO 11345:2006 - Rubber - Assessment of carbon black and carbon black/silica dispersion - Rapid comparative methods

ISO 11345:2006 provides standardized methods to visually and qualitatively assess the macrodispersion of carbon black and carbon black/silica in rubber compounds. This is essential for understanding the uniformity of the material and ensuring that it meets quality standards. The method evaluates the dispersion quality by comparing it to standard reference photographs and assigns ratings on a numerical scale.

Scope:

1. Provide rapid and comparative visual methods to determine the degree of dispersion.
2. Specify a numerical rating scale from 1 to 10 for both macrodispersion and the presence of large agglomerates.
3. Offer a consistent framework for analyzing the distribution of carbon black and silica in rubber compounds.

Applications:

1. Rubber Manufacturing: Ensures the uniform distribution of fillers to enhance product performance.
2. Material Development: Supports R&D activities for developing elastomers with optimal physical and mechanical properties.
3. Performance Evaluation: Assists in assessing the mechanical properties of rubber, which depend on filler dispersion.
4. Quality Control: Helps manufacturers maintain consistency and meet industrial standards.
