Insulation resistance, grounding continuity, withstand voltage strength, leakage current, input power deviation - all these ensure the basic safety of each product when it is in use with power.

Steam volume, steam outlet temperature, steam continuity and stability, waiting time for steam spraying, wrinkle removal rate and germ removal rate, verify the core cleaning and ironing performance.

Water-free dry heating protection, overheat protection, pressure relief valve activation, anti-scald protection, and safe responses in simulated abnormal usage scenarios.

The continuous working life of the heating element, the pressing life of the switch, the durability of the motor, and the cumulative operating time of the entire machine are evaluated to assess the reliability during long-term use.

Heavy metal migration amount, plasticizer content, bisphenol A release amount, and material food-grade certification verification. Applicable to products such as juicer cups, coffee machines, ice cream machines, etc. that come into contact with food.

Pipeline sealing performance, water tank leak prevention, cup body anti-leakage when upside down, and overall waterproof grade ensure the safety of use in humid environments.

The pressure deviation of the coffee pump, the coffee temperature, the refrigeration efficiency of the ice cream, the uniformity of juice extraction and grinding, and the uniformity of steam distribution are all verified to ensure the stability of each batch of products.
