About This Item
ASTM G142 is the ASTM standard that addresses how to determine whether metals may become embrittled in hydrogen-containing environments at high pressure, high temperature, or both. It is relevant for evaluating material performance where hydrogen exposure and demanding operating conditions can increase the risk of cracking or loss of ductility. For engineers, purchasers, and quality teams, this standard helps support more consistent testing and informed material selection for critical service conditions.
ASTM G142 standard overview
The ASTM G142 standard provides a test method focused on susceptibility to hydrogen embrittlement under severe environmental conditions. Based on its title, it is intended to support assessment of metals exposed to hydrogen-containing atmospheres or process environments at elevated pressure and temperature. That makes it a useful technical document for comparing material behavior under controlled test conditions and for helping users judge whether a metal is suitable for service where hydrogen-related damage is a concern.
Where is ASTM G142 used?
ASTM G142 is commonly used in testing and qualification workflows where metals are evaluated for service in hydrogen-containing environments. It is particularly relevant when materials may be exposed to high pressure, high temperature, or both, such as in laboratory testing, materials development, and product acceptance programs. The standard may also support procurement and verification activities when a defined method is needed to assess embrittlement susceptibility before a material is approved for demanding applications.
Practical importance of ASTM G142
In practice, ASTM G142 helps create a shared basis for testing and reporting material susceptibility to hydrogen embrittlement. That consistency is important for compliance reviews, quality control, and product evaluation because it reduces ambiguity in how results are generated and compared. Using a recognized ASTM standard can also support risk reduction when selecting metals for severe environments, especially where performance loss could affect reliability, safety, or service life.
