Introduction
EN 16475-7 is a part of the series of standards for “Chimneys — Accessories” and consists of:
— Part 1: Silencers
— Part 2: Chimney fans
— Part 3: Draught regulators, standstill opening devices and combined secondary air devices
— Part 4: Flue dampers
!deleted text"
— Part 6: Access components
— Part 7: Rain caps (this part)
1 Scope
This European Standard specifies requirements and test methods for rain caps that are used as
components, subject to flue gas, in order to protect against rain entry into the chimney flues.
Rain caps which are part of components of a system chimney or other components of a chimney such as
terminals, are not covered by this European Standard.
!Rain caps which have not the same opening on all sides or do not have at least the same shape and
cross section on the opposite sides are not covered by this European Standard."
It also specifies the requirements for marking, manufacturers’ instruction, product information and
attestation and verification of constancy of performance (AVCP).
NOTE Rain caps according to this standard are suitable for both dry and wet chimney applications.

3.1
rain cap
product to protect against rain entry into the chimney flue
3.2
flow resistance of the rain cap
additional pressure loss due to the flow of the flue gas passing the rain cap
3.3
nominal flue size
numerical designation of flue size which the rain cap is protecting against rain ingress, which is a
convenient round number equal to or approximately equal to either the internal diameter in
millimetres of circular flue liners, the internal width in millimetres of square flue liners or the internal
width and breadth in millimetres of the cross section of rectangular flue liners
3.4
rain cap size
outer dimension or dimensions of the projected horizontal surface of the rain cap, expressed in
millimetres
3.5
free area
vertical dimension from the top of the flue outlet to the underside of the rain cap edge multiplied by the
perimeter of the flue which the rain cap protects, reduced by the area of e.g. any support legs, bands,
bird or spark guard mesh, expressed in square millimetres
4 Product characteristics
4.1 General
Recommended minimum material specifications for rain caps are the following (see Annex A):

or st and a relation between dome/pyramid and height/size of at least 10 %.
b) Metal rain caps made of material quality 1.4301 with a wall thickness of the cap of at least 0,6 mm,
at least three supports with a wall thickness of each at least 1,0 mm, method of fixings ww, wr, rr, b
or st and a relation between dome/pyramid and height/size of at least 10 %.
c) Metal rain caps made of material quality EN AW – 4047A with a wall thickness of the cap of at least
1,5 mm, at least three supports with a wall thickness of each at least 1,5 mm, method of fixings rr, b
