Yichun Mobile Environmental Toilet Testing

Currently, there is no specific process or standard information directly targeting the testing of Yichun mobile environmental toilets, but the testing directions and key points can be inferred based on their characteristics.

As intelligent and portable sanitation facilities, Yichun mobile environmental toilets are equipped with anti-slip, dust-proof, and odor-proof functions, along with intelligent sensing systems and automatic cleaning devices. Their testing needs to focus on these core features.

I. Functional Integrity Testing

1. Intelligent Sensing System Testing: It is necessary to verify the sensitivity and accuracy of the sensing devices. For example, test whether functions such as door opening and lighting are triggered in a timely manner when a person approaches, and whether they automatically turn off and initiate the cleaning process after the person leaves. This can be done by simulating usage scenarios and using professional sensor testing equipment to record response times and error ranges.
2. Automatic Cleaning Device Testing: Focus on checking the uniformity of cleaning solution spraying, the intensity of brushing, and the efficiency of drying. For instance, observe whether the cleaning device can cover the entire inner wall of the toilet bowl, whether the residual stains meet hygiene standards (e.g., bacterial count ≤ 100 CFU/cm²), and whether the surface humidity after drying is below the safety threshold to prevent slipping.
3. Anti-slip, Dust-proof, and Odor-proof Performance Testing: Anti-slip testing requires simulating the friction coefficient under different floor materials (e.g., tiles, concrete) to ensure compliance with national building standards (dynamic friction coefficient ≥ 0.5). Dust-proof testing involves using a dust test chamber to simulate a sandy environment and checking whether the sealing structure effectively blocks particle intrusion. Odor-proof testing requires measuring the concentration of odors inside the toilet (e.g., ammonia and hydrogen sulfide content) to ensure they are below the human perception threshold (ammonia ≤ 0.2 mg/m³, hydrogen sulfide ≤ 0.01 mg/m³).

II. Safety and Compliance Testing

1. Electrical Safety Testing: For the circuit design of the intelligent system, it is necessary to test whether the insulation resistance and grounding resistance comply with the GB 4706.1-2005 standard to avoid the risk of electric leakage.
2. Structural Stability Testing: Simulate transportation bumps or strong wind environments to check whether the toilet frame and connectors deform or loosen, ensuring that no tipping occurs during use.
3. Environmentally Friendly Material Testing: Verify whether the main materials of the toilet (e.g., plastics, metals) contain heavy metals (such as lead and mercury) or harmful substances (such as formaldehyde), and ensure they comply with GB/T 26572-2011 'Requirements for the Limitation of Restricted Substances in Electrical and Electronic Products'.

III. Intelligent Data Monitoring (Optional) If the toilet is equipped with an IoT module, it is necessary to test the stability of data transmission (e.g., 4G/5G signal strength), remote monitoring functions (such as real-time viewing of usage frequency and cleaning status), and the accuracy of fault alarms to ensure that operation and maintenance personnel can respond to abnormal situations in a timely manner.
