The API Committee on Petroleum Measurement (COPM) provides leadership in developing and maintaining cost effective, state of the art, hydrocarbon measurement standards and programs based on sound technical principles consistent with current measurement technology, recognized business accounting and engineering practices, and industry consensus. This is accomplished through the committee's and API’s leadership role in the national and international standardization community in the development, publication, promotion, and revision of petroleum measurement standards, through its subcommittee structure, and through elimination of duplicative efforts.

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.
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.
