Description of BS EN 13598-1:2020 2020
This document specifies the definitions and requirements for
ancillary fittings and shallow chambers installed underground in
non-pressure drainage and sewerage systems and manufactured from
unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP),
polypropylene with mineral modifier (PP-MD) or polyethylene (PE)
intended for use for:
-
non-pressure underground drainage and sewerage outside the
building structure (application area code “U”), and
-
non-pressure underground drainage and sewerage for both
buried in ground within the building structure (application
area code “D”) and outside the building structure.
This is reflected in the marking of products by “U” and “UD”.
It also covers the jointing of the ancillary fittings and
shallow chambers to the pipework system.
The ancillary fittings covered by this standard are the
following:
-
sealed access fittings;
-
rodding point covers;
-
rodding tees;
-
mechanical saddles.
Ancillary fittings according to this document are intended for
use in pedestrian areas, except rodding tees and mechanical saddles
which can also be used in vehicular trafficked areas.
NOTE 1
Pedestrian areas are as defined in
EN 124?1 .
Ancillary fittings can be installed to a maximum depth of 6,0 m
from ground level, with the exception of rodding point covers.
Shallow chambers according to this document are intended for use
in private drains located in pedestrian areas above the ground
water table, to a maximum depth of 2,0 m from ground level to the
invert of the main channel. This document covers shallow chambers
with flow profile bases, and their joints to the piping system.
NOTE 2
Manholes and inspection chambers are specified in
EN 13598-2 [
1].
Ancillary fittings and shallow chambers complying with this
document also comply with the general requirements given in EN 476.
Ancillary fittings and shallow chambers can be manufactured by
various methods e.g. injection moulding, rotational moulding,
spiral winding or fabricated from components made to other
standards.
NOTE 3
Products complying with this document can be used with pipes,
fittings and other components conforming to any of the plastics
products standards listed in
Clause 2, providing their dimensions
are compatible.
NOTE 4
Products complying with this document can be installed in
underground applications without additional static
calculation.
NOTE 5
Ancillary fittings and shallow chambers can be subject to
national safety regulations and / or local provisions.
