Per navsup P-805, what does this indicator show?
- Acceptable level of humidity
- Unacceptable level of humidity
- Item is unserviceable
- Item requires reinspection
The correct answer and explanation is:
iturn0image0turn0image1turn0image6turn0image8Humidity indicators are essential tools used to monitor the moisture levels within sealed packages, especially those containing sensitive equipment such as munitions. According to the NAVSUP P-805 manual, these indicators are typically impregnated with cobaltous chloride, a chemical that changes color in response to varying humidity levels. The color transition serves as a visual cue to assess the internal environment of the packaging.
In their dry state, these indicators exhibit a blue color. As the relative humidity rises and reaches specific thresholds, the indicator changes to pink, signaling increased moisture content. The NAVSUP P-805 outlines that if the humidity indicator displays a pink color, it denotes an unacceptable level of humidity within the package. This change necessitates corrective actions, such as replacing the desiccant materials or inspecting the package for potential breaches that could allow moisture ingress.
Maintaining appropriate humidity levels is crucial for the longevity and reliability of sensitive items. Excess moisture can lead to corrosion, degradation, or compromised functionality, particularly in munitions where performance reliability is critical. Therefore, regular monitoring using these indicators ensures that any deviation from acceptable humidity levels is promptly identified and addressed, thereby preserving the integrity and safety of the stored items.
In summary, per the NAVSUP P-805 manual, a humidity indicator that has turned pink signifies an unacceptable level of humidity within the package. This visual alert prompts necessary interventions to restore optimal storage conditions and safeguard the contents from moisture-related damage.
