3 TR Test Report Verification Testing RKN e1 Container (+5 C) Worst Case Load Version: 01 Page: 3 (26) Summary The verification testing of the RKN e1 container consists of basic tests and complementary tests at different container set temperatures (i.e. +5 C and +20 C). The basic tests include worst case load tests, specification tests and autonomy tests. This report describes the worst case load tests where two different load configurations, maximum and minimum load were studied in order to define worst case load for continued testing. Both loads were tested in warm and cold conditions with a container set temperature of +5 C. Both the minimum and maximum loads were loaded on a standard US-pallet, since this is the largest pallet that is commonly used in shipments. The RKN e1 can fit larger loads, but in order to generate generic material for all Envirotainer containers, the US-pallet(s), packed according to below has been chosen as standard loads. The performance and autonomy of the Envirotainer RKN e1 container were evaluated from the result of four (4) tests carried out on one (1) container, under the conditions specified below: Purpose Test 1 Load: Minimum Temperature profile: -15 C Test 2 Load: Minimum Temperature profile: +35 C Test 3 Load: Maximum Temperature profile: -15 C Test 4 Load: Maximum Temperature profile: +35 C The main purpose of these tests was to define the worst case load for the RKN e1 container through testing of minimum load and maximum load and comparing the results. The defined worst case load will then be used for the continued verification testing. The secondary purpose of these tests was to evaluate the performance and autonomy of the container at the different ambient temperatures. The performance is defined as the duration that the container manages to maintain the product temperature between +2 C and +8 C and the autonomy is the duration until the container battery level reaches 0 %. In both the performance and the autonomy cases the duration was calculated from test start. Acceptance Criteria In order for the test to be accepted, the following criteria need to be fulfilled. Product temperature within ±2 C of container set temperature at test start Battery level at 95% or above at test start Container alerts or alarms are allowed during the test, taken that they do not affect the function or the temperature in the container in any way Climate chamber temperature within ±3 C of chamber set temperature during the test after a 2 hour stabilization period from changing the set temperature

The results show that at -15 C the container performance autonomy was approximately 27 hours. At +35 C the container performance was approximately 22.5 hours regarding both performance and autonomy. There was no major difference in performance and autonomy between the two loads for the different profiles. The tests were accepted since the acceptance criteria were fulfilled. Table 1-1.

7 TR Test Report Verification Testing RKN e1 Container (+5 C) Worst Case Load Version: 01 Page: 7 (26) 1 Introduction The verification testing of the RKN e1 container consists of basic tests and complementary tests at different container set temperatures (i.e. +5 C and +20 C). The basic tests include worst case load tests, specification tests and autonomy tests. This report describes the worst case load tests where two different load configurations, maximum and minimum load were studied in order to define worst case load for continued testing. Both loads were tested in warm and cold conditions with a container set temperature of +5 C. Both the minimum and maximum loads were loaded on a standard US-pallet, since this is the largest pallet that is commonly used in shipments. The RKN e1 can fit larger loads, but in order to generate a generic material for all Envirotainer containers, the US-pallet, packed according to below has been chosen as standard maximum load. The performance and autonomy of the Envirotainer RKN e1 container were evaluated from the result of four (4) tests carried out on one (1) container, under the conditions specified below: Test 1 Load: Minimum Temperature profile: -15 C Test 2 Load: Minimum Temperature profile: +35 C Test 3 Load: Maximum Temperature profile: -15 C Test 4 Load: Maximum Temperature profile: +35 C The tests were carried out in the Envirotainer Laboratory in Lagga, Sweden. 2 Purpose The main purpose of these tests was to define the worst case load for the RKN e1 container through testing of minimum load and maximum load and comparing the results. The defined worst case load will then be used for the continued verification testing. The secondary purpose of these tests was to evaluate the performance and autonomy of the container at the different ambient temperatures. The performance is defined as the duration that the container manages to maintain the product temperature between +2 C and +8 C and the autonomy is the duration until the container battery level reaches 0 %. In both the performance and the autonomy cases the duration was calculated from test start. 3 Scope This report applies to the Envirotainer RKN e1 container with the test setup and test procedure described in sections 9 and 10.

8 TR Test Report Verification Testing RKN e1 Container (+5 C) Worst Case Load Version: 01 Page: 8 (26) 4 Acceptance Criteria In order for the test to be accepted, the following criteria need to be fulfilled. Product temperature within ±2 C of container set temperature at test start Battery level at 95% or above at test start Container alerts or alarms are allowed during the test, taken that they do not affect the function or the temperature in the container in any way Climate chamber temperature within ±3 C of chamber set temperature during the test after a 2 hour stabilization period from changing the set temperature 5 Abbreviations and Definitions Product Empty boxes Worst case load See description in section 6 Failure In these tests defined as: product temperatures below +2 C or above +8 C recorded 6 Evaluation The worst case load is defined as the load with largest total average difference from set temperature +5 C and determined according to below: 1. Calculate the absolute difference from set temperature +5 C for each value on each sensor during a three (3) hour period. The three (3) hour period should start three (3) hours after test start (start of temperature profile) 2. Calculate the average difference from +5 C based on all values 3. The largest average is defined as the worst case load 6.1 Rationale for determination of worst case load By calculating the difference from set temperature in each measuring point for each sensor followed by calculating the total average deviation over a predetermined time range, an adequate measure of the difference from set temperature within the load is achieved. A larger total average indicates a larger deviation from the set temperature throughout the defined test period, which in turn indicates larger difficulties in maintaining +5 C. The larger total average therefore is defined as the worst case load.

9 TR Test Report Verification Testing RKN e1 Container (+5 C) Worst Case Load Version: 01 Page: 9 (26) 6.2 Example In the case below the maximum load is considered to be the worst case load since the total average difference is larger for maximum load than for minimum load, see Table 6-1, Table 6-2, Table 6-3 and Table 6-4.

Table 8-3. Technical specifications of Envirotainer climate chamber 2. Heating and cooling system The cooling system of the chamber (denomination: KA2) consists of 3 compressors connected in a cooling media circuit. There are 3 evaporators inside the chamber connected in parallel in the cooling media circuit. Electrical radiators are installed in front of the fans of the evaporators. The air flow from the fans is constant and each fan blows with a flow rate of 0.9 m 3 /s. The temperature in the climate chamber is regulated by a test control system provided by Hansson Kyl AB. Four sensors in the chamber (positioned on the walls) are used as input for the regulation system. Set temperature range Internal (L x W x H) Door opening (L x H) Dimensions Other information Installed in 2003 by Hansson Kyl i Uppsala AB (ref no 2219) -30 C to +50 C -22 F to +122 F 3.7 x 3.7 x 3.1 m x x 122 in 3.0 x 2.2 m x 86.6 in The accuracy of the climate chamber is ±3 C (±5.4 F) from set temperature. The climate chamber needs a stabilization period when a temperature change is made. 8.4 Temperature measuring device Calibration The thermocouples were calibrated in a calibration bath against a reference thermometer before and after the test series. The reference thermometer is calibrated yearly at Pentronic AB, accredited by Swedish authority to standard ISO/IEC The performance and properties of the used testing equipments are traceable, via Pentronic s accredited laboratory (SWEDAC 0076), to standards at the SP Swedish National Testing and Research Institute.

18 TR Test Report Verification Testing RKN e1 Container (+5 C) Worst Case Load Version: 01 Page: 18 (26) 9.4 Temperature profiles and charging For climate chamber set temperature during preconditioning, see Table 9-5. The temperature profiles in Table 9-6 and Table 9-7 were used in the tests. The climate chamber was programmed to the temperature profiles allowing the temperatures to automatically adjust at the times set. The container was fully charged (battery level of 95% or higher) at the start of each test. To achieve this level the batteries need to be drained to less than 80% before charging for 12 hours. The container was not charged during the profile. Table 9-5. Preconditioning.

26 TR Test Report Verification Testing RKN e1 Container (+5 C) Worst Case Load Version: 01 Page: 26 (26) 12 Conclusion The performance and autonomy of the Envirotainer RKN e1 container were evaluated from the results of four (4) tests carried out on one (1) container. Two different load configurations, maximum and minimum load, were studied in order to define worst case load for continued testing. Both loads were tested in warm and cold conditions with a container set temperature of +5 C. See Table 12-1 for a summary of the results. Maximum load obtained the largest values for the total average of absolute difference from set temperature for both the cold (-15 C) and warm profile (+35 C) and therefore maximum load is determined to be the worst case load and will therefore be used in further tests. The results show that at -15 C the container performance autonomy was approximately 27 hours. At +35 C the container performance was approximately 22.5 hours regarding both performance and autonomy. There was no major difference in performance and autonomy between the two loads for the different profiles. The tests were accepted since the acceptance criteria were fulfilled.
