Final answer:
Without additional context, it's not possible to provide a specific answer to the question regarding the pressure range for test gauges. The selection of a gauge range depends on its intended use, desired accuracy, and applicable industry standards.
Explanation:
The subject question relates to the pressure range for test gauges. Unfortunately, the question does not provide sufficient context to determine a definitive answer as test gauges can come in various pressure ranges depending on their intended use and the standards that apply to the specific field of engineering or application in question. When selecting a test gauge, it is crucial that the gauge's range is appropriate for the system it is measuring; a range that is too wide can result in a loss of accuracy, whereas a range that is too narrow can lead to overpressure and potential damage to the gauge.
In practice, the maximum pressure a gauge should measure typically does not exceed two thirds of its full scale range. For example, if a system is expected to operate at a maximum pressure of 100 psi, then a gauge with a scale up to 150 psi might be selected for optimal accuracy without too much unused scale.
It is always recommended to consult the specifications required for the particular application, as well as any applicable industry codes or standards, which provide guidelines on the selection of pressure gauges.
