API Standard 682, titled "Pumps - Shaft Sealing Systems for Centrifugal and Rotary Pumps," is the American Petroleum Institute standard for end-face mechanical seals. [1] The purpose of API 682 is to assist in the selection and operation of end face mechanical seals in centrifugal pumps .
API Standards Committees are made up of subcommittees and task groups that works and maintain these standards. [10] [11] API also defines the industry standard for the energy conservation of motor oil. As of 2020 API SP is the latest specification. It supersedes API SN. SP specifies more stringent engine oil performance requirements for spark ...

A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1
API TC is a certification for two-stroke oils, awarded by the American Petroleum Institute. It is given after the product passes through stringent tests that determine the level of detergent performance, dispersion, and anti-oxidation. It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA, TB, TC ...
European Standards (abbreviated EN, from the German name Europäische Norm ("European Norm")) [1] [2] are technical standards drafted and maintained by CEN (European Committee for Standardization), CENELEC (European Committee for Electrotechnical Standardization) and ETSI (European Telecommunications Standards Institute).
The Pressure Equipment Directive (PED) 2014/68/EU (formerly 97/23/EC) [1] of the EU sets out the standards for the design and fabrication of pressure equipment ("pressure equipment" means steam boilers, pressure vessels, piping, safety valves and other components and assemblies subject to pressure loading) generally over one liter in volume and having a maximum pressure more than 0.5 bar gauge.
ISO 3977 is an international standard related to the design and procurement of gas turbine system applications. ISO 3977 is based primarily on the ASME 133 series on gas turbines, as well as the API 616 and API 11PGT standards. The standard environmental design point of any gas turbine system is 15 °C, 60% relative humidity, and sea level ...
