Alcance y aplicabilidad

This standard applies to refrigerated vehicles and refrigerated semi-trailers modified from finalized vehicle chassis for the road transportation of perishable foodstuffs and biological products. It covers non-mechanical, mechanical, and mechanical-and-heating refrigerated vehicles, including multi-compartment configurations. Manufacturers of cold chain logistics vehicles entering the Chinese market must comply with these requirements.

Requisitos técnicos

The standard classifies refrigerated vehicles into three main types—non-mechanical, mechanical, and mechanical and heating—based on their temperature regulation devices. It further categorizes them into specific classes (e.g., A to L) depending on the internal temperature control range under specific environmental conditions. Key technical requirements include the mandatory installation of a travelling air temperature recorder with specific measurement accuracy, data storage capabilities, and independent operation from the vehicle's temperature control system. The vehicle body must meet strict criteria for air tightness, thermal insulation (overall heat transfer coefficient), and structural strength. Additionally, the standard specifies performance requirements for cooling, heating, and heat retention. Vehicles utilizing liquefied gas refrigeration systems must adhere to supplementary safety requirements, including oxygen monitoring and automatic shut-off valves. All vehicles must display specific identification marks and warning labels as defined in the standard.

Métodos de ensayo

The standard outlines several critical testing procedures to verify compliance: - Rainproof Performance Test: Evaluates the compartment's sealing against water ingress under specific rainfall intensity. - Air Tightness Test: Measures the air leakage ratio using a pressurization method to ensure compartment integrity. - Thermal Insulation Test: Determines the overall heat transfer coefficient (K-value) using an internal heating method within an environmental control chamber. - Cooling and Heating Performance Tests: Assess the vehicle's ability to reach and maintain required temperatures under defined environmental conditions. - Heat Retention Test: Verifies the compartment's ability to maintain temperature over a 12-hour continuous operation period. - Body Strength and Stiffness Test: Uses airbags to apply static loads to the front, side, and rear walls to ensure structural integrity. Manufacturers must ensure their vehicles pass these tests to achieve type approval.
