Norma ASTM D3078

Método de ensayo estándar para la determinación de fugas en envases flexibles mediante la emisión de burbujas

Materiales de prueba

ASTM D3078 specifies the use of packaging materials such as plastic films, bottles, and containers that are subjected to leak testing. The test evaluates the ability of the packaging to resist leaks under vacuum or pressure conditions. Materials should be prepared to ensure uniformity and consistency for accurate results.

Proceso de prueba

The packaging leak test involves placing the sample in a controlled chamber, where a vacuum or pressure is applied. The test checks for leaks by monitoring the pressure change or detecting bubbles in the sample. The method ensures that the container remains sealed under specified conditions, simulating real-world handling and storage.

Interpretación de los resultados de la prueba

Test results from ASTM D3078 are interpreted by measuring the degree of pressure change or leak detection over a set time. A significant change in pressure or the presence of bubbles indicates a leak, while minimal change suggests the packaging is intact. The results help assess the packaging’s ability to maintain product integrity during distribution and storage.
