ISOENASTMVerfahren

ISOENASTMVerfahren is a term used in German-speaking contexts to describe test methods and procedures that are aligned with ISO standards, European EN norms, and ASTM International standards. It denotes the use of a single testing method whose requirements and criteria are defined in one or more of these standardization bodies, so that results are comparable across laboratories and jurisdictions. The concept appears in quality management, supplier specifications, and laboratory accreditation to indicate that a procedure follows internationally recognized norms.

In practice, an ISOENASTMVerfahren involves selecting a specific standard status for the method (for example ISO, EN ISO, or ASTM), and detailing the elements of the procedure such as specimen geometry, conditioning, equipment, testing speed, and data interpretation in line with that standard. Many ISO standards are adopted by the European Union as EN ISO standards, which may be referenced alongside corresponding ASTM equivalents. Laboratories often maintain harmonized documentation, ensuring traceability to multiple standards and using calibration, proficiency testing, and inter-laboratory comparisons to demonstrate compliance.

Benefits of this approach include improved cross-border acceptance of test results, reduced duplication of testing, and clearer communication within supply chains. Challenges can arise from minor methodological differences between standards, varying national regulatory requirements, language translations, and the need to stay current with updates across several standards bodies.
