ARINC 653 (Avionics Application Software Standard Interface) is a software specification for space and time partitioning in safety-critical avionics real-time operating systems (RTOS). It allows the hosting of multiple applications of different software levels on the same hardware in the context of an Integrated Modular Avionics architecture.
The major design codes for welded atmospheric tanks are API 650 and API 620. API 653 is used for analysis of in-service storage tanks. API 653 is used for analysis of in-service storage tanks. In Europe the applicable design code is EN 14015, which uses load cases from Eurocode 3 (EN 1993), part 4-2.
ARINC 650 and ARINC 651 provide general purpose hardware and software standards used in an IMA architecture. However, parts of the API involved in an IMA network has been standardized, such as: ARINC 653 for the software avionics partitioning constraints to the underlying Real-time operating system (RTOS), and the associated API

The XtratuM API and internal operations resemble the ARINC 653 standard. XtratuM is not an ARINC 653 compliant system. The standard relies on the idea of a separation kernel defining both the API and operations of the partitions and also how the threads or processes are managed inside each partition.

Academic measures showed increases in an API score of 653 and a graduation rate of 85% for that year. For context, an API score of 615 in the year of 2010 placed Wilson in the 31st percentile of all high schools in the entire state of California and the 35th percentile of Los Angeles County high schools. [29] (The API score was abolished in ...
The American Petroleum Institute (API) oldest and most successful programs is in the development of API standards which started with its first standard in 1924. API maintains over 500 standards covering the oil and gas field. [2] The following is a partial list specific to welding:
