NOTE Before ordering a gasket it is recommended that the selection of the gasket type,
material and thickness should be made in consultation with the gasket supplier. The
selection of gasket material type and thickness should take into account the fluid,
the operating conditions, the properties of the gasket material, the type and surface
finish of the flange facing and the flange bolt loading.
EXAMPLE A gasket according to EN 12560-1, full face type (type FF), of nominal size DN 100,
Class 150, 2 mm thickness in expanded graphite, shall be designated as follows:
Gasket EN 12560-1 — FF — DN 100 — Class 150 — 2 mm — expanded graphite.

Gaskets shall be manufactured in a single material or combination of materials and shall be one of the
following designs:
a) single flat sheet; or
b) laminated ply; or
c) moulded.
NOTE 1 The selection of the gasket material should take into account the fluid, the operating
conditions, the properties of the gasket material, the type and surface finish of the
flange facing and the flange bolt loading. It is recommended that selection of
gaskets for any particular application is made in consultation with the gasket
supplier (see 4.4).
Where gaskets come, or are likely to come, into contact with water intended for human consumption, the
materials shall comply with relevant National regulations.
NOTE 2 The purchaser should indicate on the enquiry and/or order if gaskets are to be used
with water intended for human consumption (see 4.4). It should be noted that the
National regulations of both the country of origin and the country of use may be
considered relevant.

facings (see Figures 1 c) and 2 b), 2 c) and 2 d));
d) Spigot and recess type gasket (designation type SR), for use with type E/F (spigot/recess) flange
facings (see Figures 1 d); 2 b), 2 c) and 2 d));
NOTE 1 The types of flange facings are specified in prEN 1759-1:2000, prEN 1759-3:1994
and prEN 1759-4:1997 and for information, the facings are shown in Figure 3.
NOTE 2 The selection of gasket type should take into account the fluid, the operating
conditions, the properties of the gasket material, the type and surface finish of the
flange facing and the flange bolt loading. It is recommended that selection of gasket
type for any particular application is made in consultation with the gasket supplier
(see 4.4).
