Which international standards do Neway’s metallographic analysis services comply with?
Our Commitment to Standardized Metallurgical Excellence
At Neway, our metallographic analysis services are rigorously structured to comply with a comprehensive framework of international standards, ensuring the accuracy, repeatability, and global acceptance of our results. Our adherence to these protocols is fundamental to delivering the high-integrity data required for quality validation and failure analysis across all sectors we serve, from Precision Machining Service to Medical Device manufacturing.
Core International Standards for Sample Preparation and Examination
The foundation of any reliable metallographic analysis lies in consistent sample preparation. Our procedures are guided by the most recognized global standards:
ASTM E3-11: Standard Guide for Preparation of Metallographic Specimens. This is the primary standard we follow for the entire preparation sequence, which includes sectioning, mounting, grinding, polishing, and etching. It ensures that the prepared surface is free of artifacts and accurately represents the material's actual microstructure.
ASTM E407-07: Standard Practice for Microetching Metals and Alloys. We employ this standard to select and apply the appropriate etchants for revealing the microstructure of a wide range of materials, from common aluminum alloys used in CNC machining to specialized superalloy materials like Inconel and Hastelloy.
ISO 17025: General Requirements for the Competence of Testing and Calibration Laboratories While a management standard, compliance with ISO 17025 principles underpins our entire quality system. It ensures our technical competence, the validity of our results, and the traceability of our measurements to national standards.
Key Standards for Specific Microstructural Measurements
When quantitative data is required, our analysis transitions to specific measurement standards:
ASTM E112-13: Standard Test Methods for Determining Average Grain Size This is the definitive method we use for measuring grain size, a critical parameter affecting mechanical properties. This is especially important for validating the effects of Heat Treatment for CNC Machining.
ASTM E1245-03: Standard Practice for Determining the Inclusion Content of Steel We utilize this standard for performing quantitative assessment of non-metallic inclusions in steels, which is crucial for evaluating material cleanliness and predicting performance in high-stress applications.
ASTM E45-18a: Standard Test Methods for Determining the Inclusion Content of Steel This provides additional, internationally recognized methods for rating the inclusion content, ensuring our reports are understood by clients worldwide.
Industry-Specific Standards and Compliance
Our expertise extends to meeting the stringent requirements of specialized industries:
Aerospace and Defense: We regularly conduct analyses in accordance with customer- and industry-specific standards, such as those from SAE (e.g., AMS 2301 for premium aircraft-quality steel cleanliness) and NADCAP (National Aerospace and Defense Contractors Accreditation Program) requirements for chemical processing and metallurgy.
Oil & Gas: For components destined for the Oil and Gas sector, our analysis can be tailored to meet API (American Petroleum Institute) and NACE (National Association of Corrosion Engineers) standards, particularly for assessing susceptibility to sulfide stress cracking.
Automotive: Our services support the global Automotive supply chain by adhering to relevant ISO and ASTM standards required by major OEMs.
By anchoring our services in these international standards, we provide our clients with unbiased, reliable, and defensible data. This rigorous approach ensures that every component, whether a prototype from CNC Machining Prototyping or a part from Mass Production Service, meets its design intent and quality expectations.
