ASTM C773: Fired Ceramic Whiteware Compressive Strength Testing Services
ASTM C773 determines the strength of fired whitewares, a class of ceramic product, usually white. A machine compresses a sample till it breaks. The breaking force is then used to calculate the strength of the sample.

What Is ASTM C773 Fired Ceramic Whiteware Compressive Strength?
ASTM C773 determines the compressive strength of fired whiteware materials by applying a controlled load until failure. The test evaluates the ability of ceramic products to withstand compressive forces during service.
This method is widely used in ceramics, sanitary ware, and structural applications. It helps ensure material strength, durability, and reliability under load-bearing conditions.
Applications and Benefits of ASTM C773 Fired Ceramic Whiteware Compressive Strength Testing
Scope
ASTM C773 evaluates the compressive strength of fired ceramic whiteware by subjecting specimens to axial loading. The test determines the maximum load the material can sustain before failure.
The test evaluates:
- Compressive strength of ceramic materials
- Load-bearing capacity of whiteware products
- Material integrity under compression
- Effect of firing and composition on strength
- Suitability for structural applications
Applications
- Sanitary ware and ceramic fixtures
- Porcelain and whiteware products
- Structural ceramic components
- Construction and architectural ceramics
- Industrial ceramic applications
- Quality control in ceramic manufacturing
Benefits
- Provides accurate strength measurement
- Ensures the durability of ceramic products
- Supports material design and development
- Assists in quality control and production
- Enables comparison of material performance

ASTM C773 Fired Ceramic Whiteware Compressive Strength FAQs
ASTM C773 determines the compressive strength of fired whiteware materials. It evaluates the ability of ceramics to withstand crushing loads, helping assess structural integrity and suitability for load-bearing applications.
Key parameters include applied load, specimen dimensions, loading rate, and surface condition. Proper alignment and preparation ensure accurate measurement of compressive strength under controlled conditions.
The test measures maximum compressive load and calculates compressive strength. Results indicate resistance of ceramic materials to crushing and mechanical failure.
ASTM C773 is used for fired whiteware materials such as tiles, sanitary ware, and ceramic components used in construction and household applications.
ASTM C773 is conducted under controlled laboratory conditions and may not fully represent real-world performance where factors such as flaws, environmental conditions, and loading variations influence material behavior.
