Understanding Stainless Steel Certification and Compliance


Certifications in Stainless Steel Manufacturing

Certifications and standards are the bedrock of quality assurance in the stainless steel manufacturing industry. ASTM (the American Society for Testing and Materials) and ISO (the International Organization for Standardization) provides quality assurance certifications.

Certifications are formal declarations by an accredited body that a product, process, or system complies with specific requirements, often set forth in standards. Standards, on the other hand, are documents that outline precise specifications and guidelines for the design, manufacture, or performance of a particular product or process.
