API provides the public with access to key industry standards, particularly those standards that are safety-related or have been incorporated into federal regulation. Please use this site to review standards related to process safety, refinery and chemical plant operations and equipment, offshore drilling, hydraulic fracturing and well construction, and pipeline safety on welding, and public awareness programs. These standards are available for review only, and hardcopies and printable versions will continue to be available for purchase at the API Publications Store.
