Ta del standarda ISO 15848 določa preskusne postopke za oceno zunanjega tesnjenja tesnilk ventilnih stebel
(ali gredi) ter spojev izolirnih ventilov in krmilnih ventilov, namenjenih uporabi pri hlapnih onesnaževalih v zraku in nevarnih tekočinah. Končni priključni spoji, vakuumska uporaba, učinki korozije in sevanje so izključeni iz tega dela standarda ISO 15848.
Ta del standarda ISO 15848 obravnava klasifikacijske sisteme in kvalifikacijske postopke za preskušanje tipa ventilov.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
