What is the performance validation method after installing Breathable Vent Plugs - Wuxi Sinceriend New Material Technology Co., Ltd.

Air Permeability Test

This test aims to confirm that the vent plugs allow air to circulate freely between the interior and exterior of the equipment.

Primary Method: Place the installed component in a closed environment with controlled air flow. By observing the change in internal pressure over time, it can be judged whether the air permeability meets requirements.

Effective air permeability is indicated if internal pressure quickly reaches equilibrium with the external environment without obvious delay.
Qualitative observation can be performed using a gentle air source and a sensitive airflow indicator to detect flow on the opposite side.
This directly reflects whether the vent channel remains unobstructed under expected conditions.

Moisture Resistance Validation

This validation is crucial for components used in humid environments to ensure they block moisture entry while maintaining breathability.

Primary Method: Place the installed equipment in a high-humidity environment for a continuous period, then inspect the interior for signs of moisture condensation, water stains, or mold growth.

Absence of moisture-related abnormalities proves the vent plug's effectiveness.
An alternative method uses a mist spray to simulate rainy or humid conditions directed at the vent plug surface.
Checking whether internal parts remain dry after spraying verifies performance under dynamic conditions.
This approach simulates real-world usage scenarios more intuitively.

Contaminant Resistance Test

This test ensures the vent plug can prevent dust, particles, and other contaminants from entering the equipment.

Primary Method: Place the installed component in an environment with a certain concentration of dust or particles for a period of exposure.

After exposure, disassemble the equipment and inspect the interior for the presence of contaminants.
Clean internal parts without visible dust accumulation indicate good contaminant filtering performance.
A sticky film can be attached to the inner side near the vent plug before testing.
Examining the amount of contaminants on the film after testing further confirms blocking effectiveness.

Structural Stability & Installation Reliability

This validation checks whether the vent plug remains firmly installed without loosening, falling off, or deformation after stress.

Primary Method: Subject equipment with installed vent plugs to mild vibration or impact tests.

After testing, visually inspect and manually touch to confirm installation status.
Long-term placement in normal usage environments with regular inspections is recommended.
Check the vent plug's appearance and installation tightness periodically.
Ensure performance remains stable over time with no aging or damage affecting functionality.
