Predicting ISC Compliance with Confidence: The 7E Converter
ISTA will formally release the first global method for standardizing the establishment of insulating shipper container (ISC) performance, Standard 20, on September 21st. The standard aims to remove the subjectivity and interpretation of guidelines from the method by which ISCs have been tested historically. Standard 20 details not only a comprehensive validation process, the minimum physical testing requirements (ISTA 3A), but also includes the first set of Standard Global Thermal Profiles to be used to stress the ISC during performance testing under the Standard—the ISTA 7E profiles.
ISTA believes that Standard 20 is sure to be adopted by all global regulatory bodies (FDA, WHO, TGA, SFDA, EDQA, EMEA, and others) and to become the benchmark for ISC compliance requirements. To validate an ISC under Standard 20, the testing laboratory will have to be certified by ISTA first. Such Thermal Transport Laboratory Certification will take time. What can you do in the meantime to assess how your current ISC will perform under the 7E thermal profiles? How can you quickly identify whether or not the solutions you are using will meet the requirements of Standard 20? How can you immediately prove to your regulatory body that you are working to comply with the new Standard?
The First Online ISC Thermal Modeling Tool
An advanced online ISC thermal modeling tool will be offered by ISTA, the 7E Converter (www.7econverter.com). The 7E Converter is designed to be an easy-to-use program that allows you to enter your current laboratory testing data (under whatever profile you have used to qualify the ISC), and, with a click of a button, the 7E Converter will predict the thermal performance of your ISC under the ISTA 7E profiles. Results of the conversion will be displayed graphically as below and will be also available in tabular format for export to file.
The black arrow of the graphical Illustration 1.0 below shows the historical profile and performance outcomes; the green arrow points to predicted performance under the ISTA 7E Profiles.

The red arrow of the graphical Illustration 2.0 below points to the duration for which the ISC remains within acceptable ‘heat’ criterion, i.e. below 8°C, below 15°C, etc.; the blue arrow points to the duration for which the ISC remains within acceptable ‘cold’ criterion, i.e., above 2°C, above 0°C (not shown but available).

Regardless of whether the interior temperatures were obtained from air space or product temperature, the 7E Converter has the capability to generate the equivalent temperature data as if the ISTA 7E Profile had been used instead of your historical temperature profiles.
Using the Converter
In addition to the profile and payload temperature data you have on file for your ISC, only a few additional pieces of information are required. These include (1) total weight of ISC, (2) total weight of coolant used in pack-out, (3) interior surface area of payload space, and (4) latent heat of fusion of phase-change material (coolant) used. Historical data can be cut and pasted from an Excel file and can be entered in 10, 15, 20, 25, or 30 minute intervals, depending on your profile.
Refrigerated or Frozen Applications
Separate modeling tools for refrigerated and frozen applications will be offered by www.7econverter.com to cover all your shipping requirements until you can laboratory test your ISCs. If ambient/CRT or controlled frozen modeling is a requirement of yours, you can contact the 7E Converter team at email@example.com and they will custom model to 7E in accordance to your specific requirements.
Development & Validation
The 7E Converter has been validated against actual thermal laboratory testing. A full validation document will be available for download on the release date of September 21st. At less than $50 per model run, the 7E Converter was developed to be a quick, easy, and cost-effective tool for predicting compliance, predicting performance, and minimizing risk.
The 7E Converter was developed by MJ Enterprises Inc. in partnership with ISTA. For further information or to preregister for the 7E Converter, e-mail firstname.lastname@example.orgemail@example.com.
