To accomplish this, the task force created three subgroups to channel the efforts in the most efficient manner. After considerable debate, the task force changed its objective to focus on the development of an HTHS viscometer. The response to the questionnaire provided guidance for the HTHS viscosity program. A questionnaire to develop inputs on important issues was sent to engine manufacturers, oil companies, and oil additive companies. Initial efforts consisted of defining objectives and developing plans for the cooperative research required. The ASTM project began as a task force effort and later grew into a section activity. The essence of the SAE request was to develop an HTHS viscosity measurement that correlates with engine performance, either in bearing wear or piston ring wear. ASTM involvement in high-temperature, high-shear (HTHS) viscosity research began in December 1977, as a direct result of a request by the Society of Automotive Engineers (SAE).
