Mobile Toilet Acceptance Criteria

The acceptance criteria for mobile toilets cover six main aspects: acceptance main lines, material structures, sewage discharge systems, supporting facilities, testing methods, and relevant certifications. Details are as follows:

I. Acceptance Main Lines and Key Nodes

Acceptance should focus on six types of actions: 'entry, use, cleaning, replenishment, maintenance, and relocation', covering functional tests throughout the entire lifecycle of mobile toilets to ensure smooth operation and no safety hazards in all aspects.

II. Material and Structure Standards

1. Frame Structure: The main frame should be made of hot-dip galvanized steel pipes or steel structures, featuring high strength, corrosion resistance, and wind pressure resistance. The quality of welds should comply with the national standard GB/T 14952.1-2017, with a penetration depth of more than 70% of the base material thickness and surface depressions or protrusions not exceeding 0.5mm.
2. Wall Materials: Exterior walls commonly use metal carved panels or color-steel composite panels, while interior walls often use stone plastic panels or aluminum-plastic panels, filled with rock wool and other flame-retardant insulation materials.
3. Floor Treatment: Waterproof and anti-slip treatments are required, with materials such as anti-slip patterned aluminum plates or reinforced composite flooring to ensure no water seepage or ponding.

III. Sewage Discharge System Standards

1. Water-flush Direct Discharge Type: It should be connected to municipal sewage pipes, with a stable and water-saving flushing system.
2. Waterless Packaging Type/Microbial Degradation Type: The sealing performance should meet standards, with no odor leakage and degradation efficiency complying with environmental protection requirements.
3. Recirculating Water Flushing Type: The purification effect of biological treatment technology should meet standards, and the recirculating system should operate stably.

IV. Supporting Facilities and Functional Standards

1. Internal Configuration: It must include basic equipment such as exhaust fans, lighting fixtures, sinks, mirrors, shelves, paper towel holders, and hooks.
2. Ventilation and Deodorization: High-power exhaust fans or active fresh air systems should be configured to prevent odor accumulation.
3. Electrical Safety: All electrical circuits should have moisture-proof, waterproof, and grounding protection functions.

V. Testing Standards and Methods

1. Appearance and Decorative Quality: The dimensional error should be ≤5mm, the decorative layer should be flat without depressions, the joint sealing should be leak-proof, and the floor should be flat and sealed.
2. Wind Resistance Performance: The overall wind resistance should be ≥ Grade 10, earthquake resistance should be ≥ Grade 8, and the service life should be ≥ 10 years.
3. Sealing and Waterproof Testing: Spray with a water gun at a pressure of 0.1MPa for 15 minutes and check for no leakage after 1 hour.
4. Tank Sealing Performance: The storage tank should show no leakage after being left stationary for 1 hour, the toilet fixture blocking action time should be ≤3 seconds, and the cleaning port cover should open and close flexibly with good sealing.

VI. Relevant Certifications and Implementation Standards

Production should refer to national standards such as 'GB/T 18092-2000 Waterless Flush Toilets' and 'CJ/T 378-2011 Portable Toilets'.
