Container House Testing Standards
The testing standards for container houses mainly cover aspects such as structural stability, material quality, installation efficiency, adaptability to extreme environments, and fire and water resistance, as detailed below:
Structural Stability: It must comply with GB50011-2010 Code for Seismic Design of Buildings and pass actual measurements of wind and earthquake resistance performance. For example, in simulated tests of 12-level strong winds or 7-level earthquakes, the frame deformation should be below the national standard limit (e.g., 10mm), and connection joints should remain free of loosening or damage. Some standards require a wind resistance rating of no less than level 10 and an earthquake resistance intensity of no less than level 7, with higher standards needed for long-term on-site scenarios (e.g., level 13 wind resistance and level 8 earthquake resistance).
Material Quality: Steel must meet standards such as GB/T 19001-2016. Key indicators include the thickness of main beams and columns, welding processes (no cold solder joints), and anti-corrosion treatments (galvanizing or spraying). For example, the weld strength of fully steel-structured frames must meet standards, avoiding the use of thin steel plates or inferior steel to prevent insufficient wind resistance (e.g., non-standard products only achieving level 8 wind resistance).
Installation Efficiency: The assembly time for a single module is a core indicator. Some standards require a pre-assembly rate of no less than 80% at the factory, with on-site lifting time controlled within 2-4 hours and a delivery cycle of no more than 5 days for projects involving 100 units. For example, fully pre-assembled products can achieve single-box delivery in 2 hours, while semi-pre-assembled products require additional water and electricity connections and furniture assembly, taking longer.
Adaptability to Extreme Environments: Performance must be verified through wind tunnel simulations, earthquake table tests, etc. For example, under conditions in the Gobi Desert's strong wind areas or southwest earthquake zones, there should be no deformation at frame connections, tight fitting of wall color steel plates, and no displacement of internal facilities. Some standards also require export products to have international certifications such as CE and ISO to meet compliance for overseas projects.
Fire and Water Resistance: Fire resistance must comply with the B1-level flame-retardant standard, with a smoke concentration rating of Q1-level. Water resistance must pass a 24-hour heavy rain spray test, with no water leakage at seams. For example, the rock wool board insulation layer must achieve A-level non-combustibility, and PVC flooring must have low smoke emissions to avoid safety hazards in fire or humid environments.
