ISO 4992
ISO 4992:2020 is an internationally recognized standard that specifies the requirements for ultrasonic testing of steel castings. Widely used in industries such as oil & gas, heavy machinery, marine, construction, and power generation, this standard ensures cast components meet stringent quality and integrity benchmarks. At Quality Asia Certification, we offer ISO 4992:2020 certification services to help organizations demonstrate compliance with global casting inspection criteria and ensure reliable product performance under critical applications.

What is ISO 4992?
ISO 4992:2020, titled "Steel castings — Ultrasonic examination", is divided into two parts:
- Part 1: Steel castings for general purposes
- Part 2: Steel castings for highly stressed components
This standard outlines the procedures, acceptance levels, and requirements for ultrasonic testing (UT) of steel castings. It helps identify internal defects like cracks, voids, or discontinuities that may impact product performance or safety. ISO 4992 plays a critical role in maintaining high levels of quality control in manufacturing and helps organizations reduce risks of failure in end-use applications.
Why is ISO 4992 important?
As industries evolve toward zero-defect manufacturing and global compliance, ISO 4992:2020 becomes a strategic necessity. Whether you're supplying cast components to international buyers or tendering for high-risk infrastructure projects, ISO 4992 certification helps you meet:
- Customer expectations for quality and safety
- Contractual and regulatory requirements
- Demand for non-destructive testing (NDT) traceability
Moreover, the 2020 version of ISO 4992 aligns with modern inspection technologies, making it a current and reliable tool for casting quality validation.
What are the benefits of ISO 4992?
- Detect Internal Defects Early: Helps identify sub-surface discontinuities in steel castings through ultrasonic testing before they reach the client or cause operational failure.
- Assure Product Integrity: Enhances the mechanical reliability of cast components used in mission-critical applications like pressure vessels, structural parts, and heavy equipment.
- Enable Compliance with International Standards: Aligns your quality systems with global best practices in non-destructive examination.
- Enhance Product Lifespan: By ensuring defect-free castings, the product’s operational life and performance are significantly improved.
- Reduce Product Recalls or Warranty Claims: Proactive quality control minimizes the risks of defective components, saving costs and preserving brand reputation.
- Improve Market Competitiveness: Certification acts as a trust symbol for clients and stakeholders, giving you an edge in competitive bids and international projects.
