1 - OVERVIEW 概述

Components homologated by Packaging departments should ensure airtightness. However,

some appearance defects that are difficult to spot (folds, rough edges, glazing of the

bottle opening, lumps on the sealing skirts of caps...) and some dimensional deviations

may lead to risks of leakage.包装部门应确保产品的气密性.然而,一些外观的不良很难被发

现(褶皱,毛边,发亮的瓶口,密封盖边缘的肿块等)和一些外观尺寸的偏差,都有可能导致泄漏.

The supplier should deliver components without defects, however this method may

also be used to verify that there are no defects not found in the visual inspection that

affect the seal.供应商应提供良品,但是这种方法也证明了在没有影响视觉检验下并

没有发现产品的不良.
