5.3 This guide, as written, is suitable for use for catalytic materials from about 1/8 in. to about 3/4 in. It can also be used for larger parts, but this requires using a larger diameter pipe.
5.4 This guide is suitable for specification acceptance, manufacturing control, and research and development processes.
SCOPE
1.1 The resistance to breakage of formed catalysts, catalyst carriers, or catalyst pieces is determined by dropping a quantity of sample through a 25 ft length of 1 in. internal diameter pipe onto a steel plate.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Overview
ASTM D8353-20 is the standard guide developed by ASTM International for the determination of individual particle strength of low surface area catalysts and catalyst carriers using a drop test onto a steel plate. This procedure is essential for evaluating the ability of formed catalysts or catalyst carriers to resist particle size reduction during use. The method is commonly applied for ensuring catalytic material integrity in manufacturing, quality control, research, development, and specification acceptance processes.
The standard can be used with catalysts and catalyst carriers of various geometries, including spheres, pellets, and hollow cylinders. It is primarily suitable for materials ranging from about 1/8 in. to 3/4 in. in size but may be adapted for larger pieces when necessary. ASTM D8353-20 is designed in accordance with internationally recognized principles established by the World Trade Organization (WTO) for the development of international standards.
Key Topics
- Determination of Crush Strength: The drop test method measures the resistance of particles to breakage by dropping samples through a 25 ft vertical pipe onto a steel plate.
- Sample Versatility: Applicable to various particle shapes and sizes, making it versatile across different catalyst and carrier forms.
- Assessment Basis: Results are categorized on a pass (intact) or fail (broken) basis, with the final outcome represented as the percentage of samples passing the test.
- Practical Guidelines: Offers instructions on apparatus setup, sample preparation, test procedures, and data interpretation.
- Safety and Best Practices: Advises on using appropriate safety measures due to potential particle fragmentation and outlines environmental considerations for testing.
Applications
ASTM D8353-20 is widely used in several key areas:
- Catalyst Manufacturing: Measures mechanical durability in production lines, ensuring catalysts and catalyst carriers meet strength specifications before deployment.
- Quality Control: Assists in verifying the resilience and integrity of batches before market release.
- Specification Acceptance: Provides reliable, standardized data for customers and suppliers to agree on catalyst quality.
- Research and Development: Supports the evaluation and optimization of new catalyst formulations and materials.
- Process Control: Offers manufacturers a method to monitor changes in catalyst strength during storage or after treatment processes such as activation or drying.
This drop test method is especially relevant for sectors using low surface area catalytic materials, including chemical processing, petrochemical industries, and environmental applications.
