ASTM D3103 Thermal Insulation Package Testing
ASTM D3103 package testing assesses the thermal insulation quality of packages. As an ISTA and ISO 17025 certified lab, we realize the importance of D3103 thermal shock testing. Meeting the ASTM thermal insulation requirements can be difficult. We understand the challenges and guide companies through the process.
We have a reputation for helping customers achieve their package certifications. Keystone Package Testing partners with customers to achieve package compliance. Our accurate test reports are delivered quickly. Keystone takes an instructive approach throughout the entire test program.
Summary of ASTM D3103 Thermal Insulation Testing
The ASTM D3103 package integrity testing method covers the thermal insulation quality of a package and the thermal stability of its contents. These contents, when exposed, are determined for ambient temperature conditions. It is recommended that a minimum of three samples must be tested to ensure reproducibility.
ASTM D3103 thermal insulation testing evaluates the performance of thermal insulated packaging used for high-value, high-risk materials. The distribution package test method may also be used for any products that need accurate internal packaging temperatures.
This method is fit for testing packages with various internal energy sources with or without payloads. Certain items must be shipped inside these temperature-controlled packages. Factors affecting the rate of heat transfer include the insulation of the exterior package, energy source, and product payload.
Scope of ASTM Thermal Insulation Package Testing
Testing conditions within the ASTM D3103 transit method are important factors to consider. The time-temperature test profile should be established prior to testing. Likewise, it is recommended that the test profile represent the actual worst-case distribution conditions as closely as possible. Constant temperatures are noted and do not reflect actual transit conditions but may be useful for comparative purposes.
When a cooling or heat source is used, a weighed and measured quantity of refrigerant is placed in the package. When water, ice, or gels are used, the temperature of the conditioning chamber is measured before removal.
ASTM D3103 Thermal Insulation Testing Procedures
The packages are pre-conditioned at specified temperatures for at least 24 hours. During testing, packaging is configured in such a way to identify all of it’s components. If feasible, temperature probes are attached directly to the wall of the primary product package. The number of probes per package will depend on the size and number of primary containers.
Next, the package is placed on a non-conducting platform or shelf. It is placed in such a manner that no part of the package contacts the chamber floor. The package is oriented the same way it may be found while shipping. Depending on the size of the package, various orientations may occur.
After testing, the laboratory will create a test report encompassing the data collected during testing. This lab test report will include general information consisting of but is not limited to, the date, time, location, and test engineer. The number of packages tested and the number of failures recorded will also be included within the report.
Other data points added in the report also include dimensions of the package under test, its structural specifications as well as a diagram of the internal thermal component assembly.
Significance of ASTM D3103 Thermal Insulation Package Testing
Manufacturers and suppliers can assess the consistency and uniformity of their materials through this test. ASTM D3103 helps identify variations in properties such as tensile strength, elongation, tear resistance, and hardness. By monitoring these characteristics, companies can ensure their products meet desired specifications, minimizing defects and ensuring customer satisfaction.
Additionally, ASTM D3103 testing supports product development. Manufacturers can analyze the effects of different formulations, additives, and processing techniques on performance. This testing method allows for comparative analysis and optimization of compounds. This ultimately helps in the development of improved materials with enhanced mechanical properties and durability.
Lastly, this standardized testing method enables accurate characterization of the physical properties and performance of rubber compounds. By subjecting samples to ASTM D3103 testing, important data is obtained, aiding in quality control, product development, and ensuring compliance with regulatory standards.
