ASTM D7709: Pharmaceutical Bottle Water Vapor Transmission Testing Services
ASTM D7709 is used to measure the water vapor transmission rates (WVTRs) of high-barrier multiple-unit containers (bottles), high-barrier single-unit containers (blisters), and quasi-barrier single-unit containers used for packaging pharmaceutical items. The values stated in SI are considered standard.

What Is ASTM D7709 Pharmaceutical Bottle Water Vapor Transmission?
ASTM D7709 is a standardized test method for determining the Water Vapor Transmission Rate (WVTR) of pharmaceutical packaging systems. In this test procedure, the entry of water vapor into a package is measured by monitoring the weight change of a bottle containing a desiccant material in a controlled-temperature, controlled-humidity environment.
This test procedure yields a highly accurate WVTR measurement that can be used to differentiate the moisture-barrier properties of various medicinal packaging materials.

ASTM D7709 Pharmaceutical Bottle Water Vapor Transmission FAQs
ASTM D7709 measures the Water Vapor Transmission Rate (WVTR) of pharmaceutical packaging by determining the rate at which water vapor enters a sealed package. For bottles, results are typically reported in mg/bottle-day.
The standard covers high-barrier pharmaceutical bottles, high-barrier blisters, and quasi-barrier blisters. Method A applies to bottles, while Methods B and C apply to barrier and quasi-barrier blisters, respectively.
The package is tested closed and sealed and exposed to a controlled environment, typically 40°C and 75% relative humidity. Water vapor entering the package is absorbed by a desiccant, and the resulting weight gain is measured over time to calculate WVTR.
WVTR testing helps determine how effectively a container-closure system protects moisture-sensitive pharmaceutical products. It can be used to compare alternative packaging systems and evaluate their moisture-barrier performance.
Testing provides a quantitative WVTR value representing moisture ingress through the complete container-closure system. For bottles, the result is expressed in milligrams per bottle per day, allowing different packaging designs or materials to be compared.
