ISO 12135 Metallic Materials - Fracture Toughness Testing: Eurolabs Laboratory Testing Service
ISO 12135 is an international standard that specifies the method for determining the fracture toughness of metallic materials. The standard, published by the International Organization for Standardization (ISO), is widely recognized and adopted globally.
Legal and Regulatory Framework
The legal and regulatory framework surrounding ISO 12135 testing is governed by various national and international standards. In Europe, the European Committee for Standardization (CEN) publishes EN 13111, which is a harmonized standard that aligns with ISO 12135. In the United States, the American Society for Testing and Materials (ASTM) publishes ASTM E1820, which is equivalent to ISO 12135.
International and National Standards
The following international and national standards apply to ISO 12135 testing:
