ISO 7539-4 Hydrogen Embrittlement Testing: Eurolabs Laboratory Testing Service
Hydrogen embrittlement testing is a critical evaluation method used to assess the susceptibility of materials to hydrogen-induced cracking. This phenomenon occurs when hydrogen atoms diffuse into the material, leading to a significant reduction in its toughness and strength. The ISO 7539-4 standard provides guidelines for the laboratory testing of steel and other alloys to determine their resistance to hydrogen embrittlement.
Legal and Regulatory Framework
The testing of materials to prevent hydrogen embrittlement is governed by various national and international standards, including:
These standards outline the requirements for the testing of steel and other alloys to determine their resistance to hydrogen embrittlement. Compliance with these standards is essential to ensure the safety and reliability of materials used in various industries, including aerospace, automotive, and oil and gas.
International and National Standards
The International Organization for Standardization (ISO) develops and publishes international standards that provide guidelines for testing and evaluation methods. The ISO 7539-4 standard has been adopted by various countries, including the United States, Europe, and Turkey. National standards, such as ASTM A370/A370M-17 and EN ISO 7539-4:2017, are based on the ISO 7539-4 standard.
