Definition: What is failure analysis?
Failure analysis is a comprehensive analytical method used by DTI Testing to help customers dissect the causes of failure in polymer and composite materials. It provides scientific evidence for fractures, cracks, corrosion, discoloration in polymer materials, and delamination in composite materials encountered during research and production. The analysis includes fracture surface analysis, composition analysis, mechanical and thermal property comparisons, and failure replication/verification tests, thereby laying a foundation for material selection and use.
Purpose: Why conduct failure analysis?
The main objectives of failure analysis are:
- Determine the root cause of failure: Identify the specific reasons behind product failures using scientific methods.
- Improve product quality: Propose improvement measures based on failure causes to enhance product reliability and durability.
- Cost reduction: Prevent failures to minimize costs associated with maintenance, replacement, and recalls.
- Enhance customer satisfaction: Strengthen brand trust by responding quickly and resolving issues promptly.
Significance: The importance of failure analysis
Failure analysis is critical for any industry dependent on product quality and reliability. It not only helps businesses minimize losses but also enhances product competitiveness, safeguards corporate reputation, and ensures consumer safety.
Scope: Applications of failure analysis
Failure analysis finds wide applications across various fields, including but not limited to:
- Electronics and electrical industry: Analyzing failure causes in circuit boards, semiconductor devices, etc.
- Automotive industry: Investigating failures in engines, braking systems, and other critical components.
- Aerospace: Evaluating failures in aircraft structures, engines, and other systems.
- Medical devices: Ensuring performance and safety of medical equipment.
- Chemical and materials science: Analyzing material durability and failure mechanisms.
- Any field requiring assurance of product performance and safety.
Testing Standards: Standards for executing failure analysis
Failure analysis typically adheres to a series of international and domestic standards such as ISO/IEC 17025 laboratory competence standards, ASTM (American Society for Testing and Materials) standards, etc. These standards ensure the scientific rigor, accuracy, and reproducibility of failure analysis.
