Thermal Chamber Testing

Intelsius has a number of state-of-the-art climate chambers situated across two locations: in York, UK,  and Indianapolis, IN.

Our climate chambers can be programmed to perform a variety of industry standard temperature profiles, such as ISTA, AFNOR and WHO stress testing profiles, as well as having the capability to program other proprietary temperature exposures. With rates of temperature change of 3°C per minute and a temperature range of -40°C to +50°C Intelsius are able to test packging against any given thermal challenge from basic stepped or ramped profiles to intricate life like temperature exposures experienced in shipping lanes.

With access to an array of chamber sizes, Intelsius can tailor thermal testing to the number and size of packaging systems which require testing. From singular tests to simultaneous testing of multiple systems, varying in size from blood shippers to pallet shippers.  Each test is considered individually to assess the most appropriate setup, this includes determining the best payload(s) and preparation process.

Intelsius utilises real time data logging allowing for access to all thermal data during testing giving us the ability to monitor performance and maximise testing and reporting efficiencies.

Thermal Testing Procedures

Intelsius has developed a series of high quality internal testing SOPs, covering all services on offer to ensure each and every test is carried out to a high standard which is repeatable. These tests are designed to demonstrate the best possible performance for your packaging and highlight areas for improvement during product development.

Intelsius works with you to develop a full testing protocol to determine your testing needs before any testing is carried out. This document will detail the packaging to be tested, the testing procedure to be followed and how the resulting data and analysis will be presented and delivered.  For effective planning and quick turnaround, Intelsius also offers standard test protocols and templates.

Thermal Testing Reports

Intelsius reports follow state of the art performance testing methodology of insulated packaging for temperature critical payloads.

All Intelsius test reports refer to the underlying test protocol defined for a specific test or test series and are always subject to the Intelsius ISO 9001-2015 Quality Management System and the associated document change control.

Intelsius reports always contain a detailed description of the completed testing including the test setup, equipment and data as well as a complete discussion and analysis of the test results.

Temperature Monitoring and Data Handling

Accuracy, traceability and the long-term archiving of all test results are the indisputable prerequisites for temperature recording as part of Intelsius test services.
Intelsius only uses high end and extremely accurate temperature monitoring equipment from leading hardware manufacturers and service providers.
All temperature data from the sensors is recorded and stored in our database system in real-time and archived for 10 years. Therefore, all data ever recorded in a test will be available to review and meet your high standards.

Thermal Testing Equipment and Locations

All climate chambers contain multiple, three-point calibrated thermistor probes, in turn used to calibrate each chamber by thermal mapping to ensure accurate output of programmed temperature profiles. These probes are subsequently used to monitor thermal testing of packaging i.e. internal temperatures of packaging and the ambient temperature profile.

All temperature sensors used for Intelsius technical services undergo an annual three-point calibration.  The equipment is calibrated to a traceable NIST, national or equivalent standard.

All equipment used for conditioning coolants, PCM and test materials is also monitored in real-time 24 hours a day.  A fully automated alarm system can be set up to inform the technical department immediately of any deviations from the temperature specifications.  In this way, the optimum conditioning of all coolants and test samples in accordance with the specifications can always be guaranteed.
