AS 15156.3:2022
[Current]AS 15156.3:2022 adopts and modifies ISO 15156 3:2020, which provides requirements and recommendations for the selection and qualification of CRAs (corrosion-resistant alloys) and other alloys for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments whose failure can pose a risk to the health and safety of the public and personnel or to the environment.
