What is the maximum allowable range for analog test gauges according to the provided standards?

The maximum allowable range for analog test gauges is set at 200% of the test pressure. This standard is based on ensuring that the gauges can accurately measure pressures that are significantly higher than the intended test pressure while still maintaining safety and reliability.

When a gauge is rated for 200% of the test pressure, it indicates that it can handle double the intended pressure without the risk of damage or inaccurate readings. This is essential in quality assurance practices to prevent gauge failure and ensure that the testing process is safe and effective. If gauges were expected to measure pressures that exceed their design limits, this could result in inaccuracies and potentially hazardous situations.

Establishing a maximum operational range is crucial for maintaining quality and safety standards in environments where pressure testing is critical, such as in industrial, mechanical, or hydraulic applications. It ensures that testers can confidently utilize the gauges without concerns about exceeding their operating capabilities.
