Introduction
This document is based on the experience of the chemical and petrochemical industry and provides
additional requirements to those given in EN 16668 and valve product standards.
It is assumed that the essential safety requirements of the European legislation for pressure equipment
(satisfied by European product standards) and safety requirements from EN 16668 and other standards
are satisfied.
1 Scope
This document applies to valves of DN 15 and larger, made of metallic materials for chemical and
petrochemical plants. It contains additional requirements to those contained in the relevant European
product standards (e.g. EN 593, EN 1349) and EN 16668.
The use of design codes or technical rules other than described by European product standards is subject
to agreement with the purchaser.
Process control devices and safety accessories are not subject of this document.
