This involves checking the characteristics of the container and the suitability of the air chamber.

Centesimal analysis inside the neck of the container in order to validate compliance with tolerances and that there is no ovalization.

This is a thermal test designed to prevent the stopper from popping up when exposed to high temperatures (i.e. pop-up effect).

Static evaluation of liquid leakage using specific simulants under different temperature conditions (22°C, 25°C, 30°C, 35°C, -18°C). Dynamic evaluation of leakage when the product is being handled/or under stressful conditions (48h).

Behavioural analysis of the product under different climatic conditions (temperature 40°C to -10°C and humidity 70%), projected ageing with climate-controlled chamber.

Checking the suitability of the insertion/corking force (put in) and the extraction/uncorking force (put out).
