Introduction to ASTM E171
Guidelines for upholding uniform testing conditions to assess the effectiveness of packaging materials are outlined in ASTM E171. It reduces the fluctuations in test results caused by external factors by establishing optimal humidity and temperature ranges. It is crucial to check the materials used for packaging to ensure they can withstand diverse environmental conditions, such as high humidity and temperature levels. ASTM E171 is widely used in the pharmaceutical, electronics, and food packaging industries to ensure the quality and dependability of packaging solutions. Following this standard improves shelf life, consumer satisfaction, and product safety. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM E171 tests for our clients.
ASTM E171 Test Method
The method proceeds as follows:
| Apparatus Setup | Temperature and humidity chamber, weighing balance, sample containers, and data logging system |
| Major Steps | The samples are placed in the temperature and humidity chamber and maintained at 23 ± 2°C and 50 ± 5% RH for a minimum of 24 hours. The samples are weighed before and after conditioning to assess any changes. The data is recorded using the data logging system for analysis and comparison. |
ASTM E171 Specimens
| Specimen Details | The specimens are representative of the flexible barrier packaging substance that is being examined. |
| Specimen Preparation | Slice the specimens into the right dimensions or forms for examination. |
| Specimen Dimension | The specimens are usually rectangular. |
ASTM E171 Test Results
ASTM E171 findings on the material’s physical characteristics are produced during the testing of flexible barrier packaging materials. This contains details about weight, height, and other pertinent changes both before and after conditioning. The material’s response to humidity and temperature variations, moisture absorption, and dimensional stability are documented. ASTM E171 assesses the suitability of the material for packaging purposes in addition to its performance under certain environmental conditions.
Tests Related to ASTM E171
ASTM E171 is similar to ASTM D709, which provides guidelines for the testing, production, and manufacture of plastic-coated thermosetting materials, while ASTM D618 offers information on the temperature and humidity conditions for plastics testing.
