ANSI C, ISO C and Standard C refer to the successive standards for the C programming language published by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO). Historically, the names referred specifically to the original and best-supported version of the standard. Software developers writing in C are encouraged to conform to the standards, as doing so helps portability between compilers.
ISO 3864 specifies international standards for safety symbols. These labels are graphical, to overcome language barriers. The standard is split into four parts:
In music, timbre is the perceived sound quality of a musical note, sound or tone. Timbre distinguishes different types of sound production, such as choir voices and musical instruments, such as string instruments, wind instruments, and percussion instruments. It also enables listeners to distinguish different instruments in the same category.
Nondestructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. The terms nondestructive examination (NDE), nondestructive inspection (NDI), and nondestructive evaluation (NDE) are also commonly used to describe this technology. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. The six most frequently used NDT methods are eddy-current, magnetic-particle, liquid penetrant, radiographic, ultrasonic, and visual testing. NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art. Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
ANSEL, the American National Standard for Extended Latin Alphabet Coded Character Set for Bibliographic Use, was a character set used in text encoding. It provided a table of coded values for the representation of characters of the extended Latin alphabet in machine-readable form for thirty-five languages written in the Latin alphabet and for fifty-one romanized languages. The standard was reaffirmed in 2003 although it has been administratively withdrawn by ANSI effective 14 February 2013. It is registered as Registration # 231 in the ISO International Register of Coded Character Sets to be Used with Escape Sequences.
A pure tone is a tone with a sinusoidal waveform; this is, a sine wave of any frequency, phase, and amplitude.
The Project Management Institute (PMI) is a global nonprofit professional organization for project management.
The Acoustical Society of America (ASA) is an international scientific society dedicated to generating, disseminating and promoting the knowledge of acoustics and its practical applications.
X3J13 is the name of a technical committee which was part of the International Committee for Information Technology Standards. The X3J13 committee was formed in 1986 to draw up an American National Standards Institute (ANSI) Common Lisp standard based on the first edition of the book Common Lisp the Language, by Guy L. Steele Jr., which was formerly a de facto standard for the language. The primary output of X3J13 was an American National Standard for programming language Common Lisp (X3.226/1994), approved December 8, 1994. X3J13 later worked with International Organization for Standardization (ISO) working group SC22/WG16 on an internationally standardised dialect of Lisp named ISLISP.
The InterNational Committee for Information Technology Standards (INCITS),, is an ANSI-accredited standards development organization composed of Information technology developers. It was formerly known as the X3 and NCITS.
The American National Standards Institute–Nanotechnology Standards Panel (ANSI-NSP) enables stakeholders in nanotechnology to work together to coordinate the development of voluntary standards. Such standards include terminology and materials properties and measurement procedures to facilitate commercialization of applications and uses of nanotechnology. ANSI established the panel in August 2004, and membership is open to all parties interested in nanotechnology standards.
A sound level meter is used for acoustic measurements. It is commonly a hand-held instrument with a microphone. The diaphragm of the microphone responds to changes in air pressure caused by sound waves. That is why the instrument is sometimes referred to as a Sound Pressure Level (SPL) Meter. This movement of the diaphragm, i.e. the sound pressure deviation, is converted into an electrical signal.
S88, shorthand for ANSI/ISA-88, is a standard addressing batch process control. It is a design philosophy for describing equipment, and procedures. It is not a standard for software, it is equally applicable to manual processes. It was approved by the ISA in 1995 and updated in 2010. Its original version was adopted by the IEC in 1997 as IEC 61512-1.
ANSI/ISA-95, or ISA-95 as it is more commonly referred, is an international standard from the International Society of Automation for developing an automated interface between enterprise and control systems. This standard has been developed for global manufacturers. It was developed to be applied in all industries, and in all sorts of processes, like batch processes, continuous and repetitive processes.
The Air Movement and Control Association International, Inc. (AMCA) is a long-established American trade body that sets standards for Heating, Ventilation and Air Conditioning (HVAC) equipment. It is best known for its ratings in fan balance and vibration, aerodynamic performance, air density, speed and efficiency.
IEC 62264 is an international standard for enterprise-control system integration. This standard is based upon ANSI/ISA-95.
In science and engineering, a power level and a field level are logarithmic measures of certain quantities referenced to a standard reference value of the same type.
ANSI/EIA-649, "National Consensus Standard for Configuration Management", is an industry standard for Configuration Management.
