Revised regularly since its first publication in 1934 (the sixth edition was published in 1993), this seventh-edition manual does not aim to present exhaustive coverage, but instead focuses on discussing what tests are done on various petroleum products, and why they are done. Twenty contributions characterize the properties of aviation fuels, automotive gasoline, crude oils, heating and lighting fuels, lubricating oils, and petroleum oils for rubber, among other products and includes chapters on sampling techniques, environmental testing, and test quality assurance.
