Information technology - Object management group systems modeling language (OMG SysML)
The purpose of ISO/IEC 19514:2017 is to specify the Systems Modeling Language (SysML), a general-purpose modeling language for systems engineering. Its intent is to specify the language so that systems engineering modelers may learn to apply and use SysML; modeling tool vendors may implement and support SysML; and both can provide feedback to improve future versions. Note that a definition of…

Ultrasonics - Hydrophones - Part 2: Calibration for ultrasonic fields up to 40 MHz
IEC 62127-2:2007+A1:2013+A2:2017 specifies absolute hydrophone calibration methods and relative (comparative) hydrophone calibration methods. This standard is applicable to:
- hydrophones used for measurements made in water and in the ultrasonic frequency range up to 40 MHz;
- hydrophones employing circular piezoelectric sensor elements, designed to measure the pulsed wave and continuous wave…
ISO 6246:2017 specifies a method for determining the existent gum content of aviation fuels and the gum content of motor gasoline or other volatile distillates. It includes the determination of products containing ethanol (up to a volume fraction of 85 %) and ether-type oxygenates and deposit control additives.
For determination of gum content in automotive ethanol (E85) fuel, no precision data…
