Comprehensive Guide to ISO 204 Creep Testing Laboratory Testing Service by Eurolab
Standard-Related Information
ISO 204 Creep Testing is a laboratory test that measures the creep behavior of materials under constant stress over a long period. The test is governed by various international and national standards, including:
ISO 204:2018: Metallic materials - Uniaxial creep testing in tensionASTM E139-19: Standard Test Methods for Conducting Creep, Relaxation, and Stress-Rupture Tests of Metallic MaterialsEN ISO 204:2018: Metallic materials - Uniaxial creep testing in tensionTSE EN ISO 204:2018: Metallic materials - Uniaxial creep testing in tension (Turkish Standard)API 6A:2019: Specification for Wellsite EquipmentThese standards outline the requirements and procedures for conducting creep testing, including test conditions, specimen preparation, and data analysis. The legal and regulatory framework surrounding this testing service includes:
Regulation (EC) No 305/2008 of the European Parliament and of the Council on a new approach to technical harmonization and innovation in the field of machineryDirective 2009/105/EC of the European Parliament and of the Council relating to electrical equipment for use in low voltage distribution systems in the European Community (LVD Directive)The international standard development organizations responsible for these standards include:
International Organization for Standardization (ISO)American Society for Testing and Materials (ASTM)European Committee for Standardization (CEN)Turkish Standards Institution (TSE)American Petroleum Institute (API)Standards evolve and get updated to reflect changes in technology, materials, and testing methods. The latest version of ISO 204:2018 was published in March 2018.
