Which standards are applied to gauges in boiler systems?

The correct choice is based on the fact that ASME (American Society of Mechanical Engineers) and ANSI (American National Standards Institute) are two key organizations that set standards for the design, construction, and maintenance of boiler systems, including the specifications for gauges used in those systems.

ASME codes outline the requirements for materials, design, and safety that must be adhered to when manufacturing and installed in a boiler system. This includes guidelines on how gauges must be constructed to ensure accuracy and reliability under high-pressure conditions. ANSI complements these standards by ensuring that there is national consensus on the practices and procedures related to various equipment, including pressure gauges.

The application of ASME and ANSI standards ensures that gauges can withstand the operating pressures of a boiler and provide reliable readings, which are crucial for the safe operation of high-pressure systems. These standards help prevent malfunctions that could lead to dangerous situations, thereby promoting safety and efficiency in boiler operations.

The other options provided refer to standards relevant to different fields or regions but do not specifically address the standards applicable to gauges in boiler systems. Thus, understanding the significance of ASME and ANSI in this context highlights why this choice is the appropriate answer.
