Overview
ASTM C368 specifies a test method for evaluating the impact resistance of ceramic tableware such as plates, bowls, and cups. The test determines the ability of ceramic products to withstand sudden impacts without cracking or breaking.
This method is widely used in the ceramics and consumer goods industries. It ensures the durability and reliability of tableware during handling, transportation, and everyday use.
Scope, Applications, and Benefits
Scope
ASTM C368 evaluates the resistance of ceramic tableware to impact by subjecting it to controlled удар forces. The test helps determine the durability and strength of ceramic products under sudden loading conditions.
The test evaluates:
- Resistance to impact and chipping
- Structural integrity under sudden force
- Durability during handling and usage
- Quality and consistency of ceramic products
- Suitability for consumer applications
Applications
- Ceramic plates, bowls, and cups
- Porcelain and stoneware products
- Household and commercial tableware
- Hospitality and food service items
- Quality control in ceramic manufacturing
- Product durability testing
Benefits
- Ensures the durability of ceramic tableware
- Helps reduce product breakage and defects
- Supports quality control and manufacturing consistency
- Assists in product design improvement
- Enables comparison of ceramic material performance
Test Process
Sample Preparation
Ceramic tableware items are inspected and prepared for testing.
1Impact Setup
Specimens are positioned in the impact testing apparatus.
2Impact Application
A controlled impact force is applied using a standardized striker.
3Data Recording & Evaluation
Damage or failure is observed and evaluated against acceptance criteria.

Frequently Asked Questions
ASTM C368 includes impact energy, striker type, drop height, specimen support, and failure criteria, evaluating resistance of ceramic tableware to mechanical impact under controlled laboratory testing conditions simulating accidental handling and usage.
ASTM C368 determines impact resistance by identifying whether specimens crack, chip, or fracture under specified impact conditions.
ASTM C368 is commonly applied to ceramic tableware including plates, cups, bowls, and other household ceramic products.
ASTM C368 requires an impact testing apparatus with controlled drop height or striker mechanism to apply consistent impact energy.
ASTM C368 evaluates impact resistance under controlled laboratory conditions and may not fully represent real-world handling, repeated impacts, or environmental factors affecting durability of ceramic tableware.
