Black Seal High Pressure License Practice Exam

Question: 1 / 400

According to N.J.A.C. 12:90, what defines a high-temperature hot water heating boiler?

Exceeds 200 degrees F at 150 psi

Exceeds 250 degrees F at 160 psi

A high-temperature hot water heating boiler is defined by its operating temperature and pressure, which significantly exceed standard values for conventional hot water systems. In this case, the definition includes parameters that identify it as high-temperature due to the combination of both elevated temperature and pressure.

This specific definition aligns with the requirement that the boiler must operate at a temperature exceeding 250 degrees Fahrenheit at a pressure of 160 psi. This specification indicates the system is designed for high-performance applications, where both temperature and pressure are critical for safe and efficient operation.

The other options describe conditions that either do not reach the established threshold or significantly exceed typical high-temperature definitions, making them unsuitable for classification as a high-temperature hot water heating boiler according to the standards set forth in N.J.A.C. 12:90. Hence, the criteria presented in the correct choice accurately reflects the regulatory definitions used in the field.
