Important:
The observations documented in this appendix relate solely to the practical assessment described in the associated report and should not be interpreted as a performance evaluation, qualification, or validation of any ATP-IR- or ATP-IN-classified insulated container, insulated packaging system, or complete distribution operation.

A.1 Test Objectives

The purpose of this practical assessment was to obtain additional insight into the thermal characteristics of an FB800 cooling plate under controlled conditions and to compare the observed temperature profile with temperature ranges commonly associated with frozen-product logistics.

The assessment formed part of a broader technical review of temperature-control methods and cooling media used in insulated distribution systems for chilled and frozen products. Particular attention was given to the relationship between the cooling plate’s measured thermal performance and commonly referenced frozen-product temperature requirements of -18°C for storage and -15°C for short-duration transport and distribution operations.

The objectives of the assessment were to:

• Observe the thermal behaviour of the FB800 cooling plate following conditioning at approximately -26°C.
• Monitor temperature development using independent SenseAnywhere temperature-monitoring equipment.
• Record temperatures directly near simulated product load, and within the airspace directly beneath the cooling plate.
• Compare the observed temperature profile with commonly applied frozen-product reference temperatures of -18°C and -15°C.
• Provide an objective technical observation that may contribute to discussions concerning cold-chain performance, cooling-media selection and the principle of “Fit for Intended Use” within temperature-controlled logistics operations.

This assessment was limited to the observation of the thermal behaviour of the FB800 cooling plate within the test configuration described in this appendix. It was not intended as a validation of a complete packaging system, insulated container, transport operation or operational procedure. The observations and data presented should therefore be regarded as a practical technical assessment only.

A.2 Materials Used

The practical assessment was conducted using a limited number of test components selected to create a controlled and repeatable environment for observing the thermal behaviour of the FB800 cooling plate. All materials used during the assessment are listed below.

Test Configuration

The ATP-IN classified EPP insulated box was used solely as a controlled test environment and was not itself the subject of evaluation.

Frozen water-filled cassettes were used as product simulants to represent a frozen thermal mass within the insulated container. Temperature measurements were performed using independent SenseAnywhere monitoring devices positioned within the simulated product load, within the airspace beneath the FB800 cooling plate and in the surrounding ambient environment.

Prior to testing, the FB800 cooling plate, product simulants and temperature-monitoring equipment were conditioned in a freezer operating at approximately -26°C to ensure a stable and repeatable starting condition.

The selected materials and test configuration were intended exclusively to facilitate observation of the thermal characteristics of the FB800 cooling plate and should not be interpreted as a validation of a complete packaging system, insulated container or transport operation.

A.3 Test Environment

The assessment was performed under controlled ambient conditions at the DEISKO office location in Istanbul, Türkiye, on 9 July 2026. The test setup was positioned in a shaded environment and protected from direct solar radiation in order to minimise the influence of external heat gain and create stable conditions throughout the observation period.

The insulated test container remained stationary for the duration of the assessment and was not subjected to handling, transport-related movement or mechanical disturbance. The objective was to evaluate the thermal behaviour of the FB800 cooling plate under repeatable and stable ambient conditions rather than under dynamic distribution conditions.

A.4 Conditioning Procedure(s)

Prior to commencement of the assessment, the FB800 cooling plate, the eutectic pre-conditioning plate, the product simulants and the temperature monitoring equipment were conditioned for approximately 24 hours in a freezer operating at approximately -26°C.
The freezer temperature profile recorded during the conditioning period is shown in Figure 4.

On 9 July 2026 at 14:30, the FB800 cooling plate and associated cooling media were visually inspected and confirmed to be fully frozen, with no detectable liquid movement within the plate.

Following this verification, the ATP-IN classified EPP box was pre-chilled for one hour using a fully charged Olivo TOP64 eutectic plate (-3°C) to establish a stable internal environment prior to assembly of the final test configuration.

Pre-chilling commenced at 14:40 and concluded at 15:40.

Following completion of the one-hour pre-conditioning phase, the TOP64 eutectic plate was removed and preparation of the final FB800 test configuration commenced.

A.5 Logger / Sensor Positions

The practical assessment was designed specifically to observe the thermal behaviour of the FB800 cooling plate within a controlled and repeatable test configuration. The assessment focused exclusively on the cooling medium itself and was not intended to evaluate the performance of the insulated container, the pre-conditioning plate or a complete temperature-controlled distribution system.

• Ambient conditions outside the insulated box;
• In between the simulated product load;
• The airspace beneath the FB800 cooling plate.

The installation sequence and logger positions are documented below.

Installation of the Test Components

Two ice cube cassettes were placed at the bottom of the EPP box.

A first SenseAnywhere logger (ER-TH 20-20-25/00) was positioned between the ice cube cassettes. An additional ice cube cassette was then placed directly over the logger.

This logger was intended to monitor temperatures within the product simulation area.

A support frame was subsequently installed above the ice cube cassettes.

A second SenseAnywhere logger (ER-TH 20-20-25/00) was positioned beneath the location where the FB800 cooling plate would be placed.

The logger was intentionally installed without direct contact with the cooling plate to prevent conductive measurement effects and to allow monitoring of the surrounding air temperature and cooling airflow generated by the FB800.

Following installation of the support frame and completion of logger positioning, the conditioned FB800 cooling plate was placed above the simulated product load.

The support frame ensured separation between the cooling plate and the product simulants while allowing the airspace logger to monitor the local temperature conditions generated by the FB800 cooling plate without direct conductive contact.

Following installation of the FB800 cooling plate, the insulated container was closed and continuous temperature monitoring commenced.

A.7 Supplementary Environmental Observations

The practical assessment was conducted under relatively stable ambient conditions throughout the monitoring period.

In addition to ambient temperature, relative humidity was continuously recorded using independent SenseAnywhere monitoring equipment. Although relative humidity was not a primary assessment parameter, it was documented as part of the environmental conditions surrounding the test.

Temperature and humidity can influence heat transfer characteristics and may affect the behaviour of cooling media through mechanisms such as condensation, surface evaporation and moisture exchange. For this reason, the ambient humidity profile has been included as supplementary environmental information.

The recorded ambient conditions remained within a relatively narrow operating range throughout the assessment period and did not indicate any unusual environmental fluctuations that would be expected to materially influence the observations described in the main report.
