For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.
This European Standard includes three informative and three normative annexes:
ANNEX A: Guidance for the assessment of conformity (informative);
ANNEX B: Test method for connections to sewer (normative);
ANNEX C: Negative pressure test on units (normative);
ANNEX D: Test method for gas-tightness of inspection chambers and manholes (informative);

NOTE Separate ENV standard prCEN/TS 14632 , extended with annex A, covers the assessment of conformity.
Introduction
The performance of a sewerage network constructed with these products depends not only on the properties
of the product as required by this standard but also on the design and construction of the network as a whole
in relation to the environment and conditions of use.

prEN 15383:2005 (E)
1 Scope
This standard specifies the requirements for GRP-UP manholes and inspection chambers, with circular
chamber and shaft sections, for use within a drain or sewer system under gravity or at low head of pressure,
limited by non-pressure classification as defined in Clause 3.
This European standard covers components to be used in systems for the conveyance of one or more of the
following fluids:
domestic wastewater;
surface water;
other waste waters (e.g. trade effluent).
Products covered by this standard are either complete manholes and inspection chambers or individual units
for the construction of manholes and inspection chambers, with an intended use in buried applications.
It specifies definitions, material specification and properties, types, characteristics, requirements, test methods,
marking.
NOTE Complete manholes or prefabricated units can also be used for other purposes such as pumping stations,
manholes for pipeline-equipment, backdrop manholes, ramp manholes, combined sewer overflow, storm water overflow,
items of drainage, housings for waste water treatment systems, items for sewerage treatment or sewerage disposal, when
corresponding additional requirements according to the relevant European Standards are fulfilled. If used in drinking water
systems, the requirements of the relevant standards for products in contact with drinking water shall apply to the
components in contact with drinking water.
