Introduction

This document provides a set of quality assurance procedures which is applicable to a wide range of gasket

types encompassing most types of industrial applications.
---------------------- Page: 5 ----------------------
EN 14772:2005 (E)
1 Scope

This document specifies the quality assurance procedures that are applicable to ensure that delivered gaskets

comply with the relevant product standards. This document sets down procedures by which a user can have

confidence that the salient features of each batch of gaskets or gasket materials delivered to him will be

constant.

The gasket types covered by this document are those that are within the scope of the series of standards

EN 1514 and EN 12560 and are simultaneously within the scope of the series of standards EN 1591. An ex-

ception is those gaskets intended solely for domestic fluids (like water, waste water ...) which are based on

rubber with or without reinforcement like fillers and/or inserts.
