Which standards are used for the calibration of gauges?

1. ISO and IEC

2. ASME and ANSI

3. ASTM and DIN

4. IEEE and NIST

The correct answer is: ASME and ANSI

The calibration of gauges is primarily governed by standards set forth by ASME (American Society of Mechanical Engineers) and ANSI (American National Standards Institute). These organizations work to establish guidelines and protocols that ensure measurement devices, including pressure gauges, are accurate and reliable. ASME provides standards related to the performance and calibration of various mechanical devices, while ANSI promotes the voluntary consensus standards that help ensure uniformity across different industries. Utilizing these standards ensures that the gauges meet specific criteria for accuracy, precision, and reliability, which are critical in applications such as low pressure boiler operations. The other sets of standards provided do not focus specifically on gauge calibration in the same manner. For example, ISO and IEC are more focused on international standards applicable to a wide range of electronic and electrical devices, while ASTM and DIN pertain to materials testing and specification, and IEEE and NIST involve broader electrical and scientific standards rather than specifically addressing gauge calibration.
