UIC Leaflet No: 574 – Chapter 5 – Rolling Stock – Insulated, refrigerator and mechanically-refrigerated wagons and containers. Procedure to be followed for the determination of the thermic transmission coefficient of the body

UIC Leaflet No: 574 – Chapter 5, Rolling Stock – Insulated, refrigerator and mechanically-refrigerated wagons and containers, provides guidelines for determining the thermic transmission coefficient of the body. This coefficient is an important parameter for evaluating the thermal insulation properties of railway wagons and containers used for transporting temperature-sensitive goods.

The determination of the thermic transmission coefficient involves a specific procedure that ensures accurate measurement and assessment. By following these guidelines, professionals in the railway industry can effectively evaluate and compare the performance of different rolling stock designs.

This procedure typically involves measuring the heat flux through the walls of the insulated or refrigerated body, as well as the temperature difference between the inside and outside surfaces. The UIC leaflet provides detailed instructions on how to perform these measurements accurately and consistently. It also outlines the calculation methods required to determine the thermic transmission coefficient based on the measured data.

Understanding the thermic transmission coefficient is crucial for optimizing the design and operation of rolling stock used for transporting perishable goods. By assessing this coefficient, engineers and technical personnel can identify areas that require improvement in terms of thermal insulation. This information helps in enhancing energy efficiency, reducing temperature variations, and ensuring the quality and integrity of the transported goods.

In summary, UIC Leaflet No: 574 – Chapter 5 offers valuable guidance on determining the thermic transmission coefficient of insulated, refrigerator, and mechanically-refrigerated wagons and containers. By adhering to the prescribed procedure, professionals in the railway industry can accurately assess the thermal insulation performance of these vehicles, leading to improved design and operation.
