Air Mode Active Containers Conditioning Performance
Description / Abstract:
Purpose
This Aerospace Recommended Practice (ARP) defines a series of test procedures to determine the temperature conditioning performance of air mode containers with active conditioning systems, a classification system for air mode containers with active condition systems, a standard means of expressing conditioning performance within each classification and a standard means of documenting test results.
Field of Application
This ARP is intended to provide users, purchasers and operators with a single method for testing and documenting the conditioning performance of air mode containers with active conditioning systems. The test method identifies the limits of performance and autonomy at these limits.
The conditioning performance of an air mode container with active temperature control is a function of the performance of both passive features, such as insulation material, and active features, such as heating and / or cooling systems. This ARP applies only to air mode containers with active temperature control. ARP1523, Air Mode Insulated Containers – Thermal Efficiency Requirements is the applicable standard for air mode containers with only passive features.
This ARP organizes industry requirements for temperature sensitive transportation into three performance classes.
Class A, Frozen, covers a set point range of -25 °C to 0 °C.
Class B, Cool, covers a set point range 0 °C to 15 °C.
Class C, Room Temperature, covers a set point range 15 °C to 30 °C.
It is not necessary for the test subject to support the full range of performance classes but it shall support a set point within the range of at least one of the performance classes.
Within each performance class, this ARP mandates a set point to be used in the test procedures. The test procedures defined within this ARP may be repeated at alternative set points within the performance class range.
The mandatory set points within each performance class range are as follows:
Class A – Mandatory set point -20 °C.
Class B – Mandatory set point 5 °C.
Class C – Mandatory set point 20 °C.
In the event of a failure of the conditioning systems in an air mode active container the reversionary performance of the container is solely attributable to the passive features of the design and should be in compliance with ARP1523, Air Mode Insulated Containers – Thermal Efficiency Requirements.
