Standards Committees


API’s Standards Committees are made up of subcommittees and task groups comprised of industry experts who develop API standards. These groups identify the need, then develop, approve, and revise standards and other technical publications. New projects must be justified by valid business and safety needs. The standards-writing subcommittees and task groups are open to representatives of groups that are materially affected by the standards. These include oil and gas companies, manufacturers and suppliers, contractors and consultants, and representatives of government agencies and academia.

Rail

The Rail Standards Committee (RSC) is responsible for developing, maintaining, approving, and interpreting API standards on rail transportation (including rail-related operations, tank cars, product handling, and transload activities) of petroleum and petroleum products.

API rail standards whose scopes include measurement techniques only are the responsibility of the Committee on Petroleum Measurement (COPM). Coordination between COPM and RSC will be required for these standards.


Pipeline

The API Pipeline Standards Task Groups are dedicated to developing, revising, and approving standards for us in the pipeline and related sectors of the oil and gas industry. The documents that are developed and maintained by the sectors address topics of safety, integrity,operations and maintenance of existing and new pipelines, as well as covering current technologies, codes and regulations, and key issues relevant to today's market. Document development is led by recognized industry experts in order to incorporate topics on proven techniques and best practices for pipeline design, construction and integrity management. These subject matter experts come from operating companies, engineering firms, vendors, consultants, academia, and both state and federal regulators.

Specific areas of focus address activities that are both regulatory and non-regulatory in nature, including integrity management, public awareness, control room management, SCADA systems, design and testing, underground storage facilities, emergency response, construction and inspection, operator qualifications, and safety management.
