Protect Your Products from Temperature Extremes

Thermal Testing Transportation Simulation

Don't Let Temperature Fluctuations Compromise Your Products

From the scorching summer heat to the freezing winter cold, your product faces plenty of environmental conditions on its journey to your consumer. How well will your packaging protect your temperature-sensitive products from these extreme conditions? 

Wiyou can uncover the hidden vulnerabilities of your insulated packaging solutions and safeguard your products against potential damage.

At Purple Diamond, we specialize in thermal testing transportation simulation as part of our comprehensive cold chain package testing, providing you with the insights needed to make informed decisions about your packaging designs. Whether you’re shipping your products via plane, ship, or truck, let us help you defend against the harsh nature of global shipping.

What is Thermal Transport Testing?

Thermal testing evaluates the effects of external temperature exposures for packaged-products during the shipping and handling stage. By subjecting packaged products to carefully controlled temperature cycles that mimic real-world scenarios, this testing helps manufacturers identify potential weaknesses in their thermal packaging designs. Packages can be tested against both extreme heat and extreme cold.

What Products Benefit from Thermal Testing?

From life-saving pharmaceuticals, like vaccines and medications, to fresh food items and the latest cosmetics, thermal testing ensures that products maintain their efficacy and safety during transit.

Pharmaceuticals

Thermal testing can help identify the temperatures at which pharma products are safe & effective.

Food Products

When perishable foods, like meat and dairy, are most likely to spoil can be determined by thermal testing.

Biomedical Products

Thermal testing can help determine the temperature at which certain biomedical samples lose sterility.

Electronics

Some electronics may not withstand extreme heat. Thermal testing can help determine temperature ranges.

Cosmetics

When cosmetics lose consistency can be determined with thermal testing.

Medical Devices

Thermal testing can help determine whether medical devices are sensitive to hot or cold temperatures.

ISTA 7D: The Standard for Thermal Testing

To help you maintain the integrity of your temperature-sensitive products, Purple Diamond offers ISTA 7D Thermal Testing as part of our cold chain testing services.

This development test evaluates the effects of external temperature exposures for packaged-products. The procedure is used to create harsh worst-case hazards in a laboratory environment while comparing multiple design variation thermal packaging systems. This procedure can also be used as a starting point for comparing various thermal package design types.

ISTA 7D Standard Test Procedure

Understanding how products react to varying temperature conditions during transportation is essential for maintaining their quality and safety. The ISTA 7D thermal testing procedure provides a systematic approach to simulating these real-world scenarios. At Purple Diamond, our package testing experts thoroughly analyze your packaging and product by performing the following steps. 

Objectives are determined by the product to be tested and the type of transportation to be simulated. Then, the temperature range and testing duration are determined. 

The sample must be packaged according to its physical and thermal properties. Then, temperature sensors are attached.

The packaged sample is placed inside one of our thermal chambers, which will simulate the temperature and humidity conditions. The sensors are connected to a monitoring system.

Pre-conditioning helps ensure that the test sample is at a stable temperature and the packaging is not damaged.

Simulate the transportation environment by subjecting the packaged product to temperature and vibration cycles that mimic the actual transportation conditions.

Collect and analyze the temperature and vibration data to determine if any damage or degradation to the product or the packaging has occurred.

Based on the test and its results, a report is created that outlines the product’s resistance and durability. Any recommended improvements may be suggested.

FAQs: Thermal Testing with ISTA 7D

Want to learn more? Here are some frequently asked questions about thermal testing and its unique features, applications, and importance. 

A typical ISTA 7D test duration can range from 24 to 96 hours. This can be longer or shorter depending on the shipping scenario being simulated and specific industry regulations. 

Yes, we test for both hot and cold temperature extremes. Cold temperature ranges are usually anywhere from 14°F to 64°F, while hot temperature ranges are typically 72°F to 95°F.

Any industry that is manufacturing or transporting temperature sensitive goods will benefit from ISTA 7D thermal testing. These industries include, but aren’t limited to, cosmetics, pharmaceuticals, medical devices, biologics, food and beverage, and electronics.

ISTA 7D is a flexible thermal testing standard that allows for customized temperature profiles, making it primarily a development test for comparing different thermal packaging designs. It features more extreme temperature ranges and simpler temperature profiles.

Several key parameters are measured, including internal package temperature, external ambient temperature, the
temperature change rate, temperature maintenance duration, thermal lag, and condensation formation, among others.
