— This document provides no information as to whether the product may be used without restriction
in any of the member states of the EU or EFTA;
— It should be noted that, while awaiting the adoption of the verifiable European criteria, existing
national regulations concerning the use and/or the characteristics of this product remain in force.
— The requirements with regard to the drinking water quality are specified in national regulations.
1 Scope
This document applies primarily to copper alloy and stainless steel ball valves with dimensions DN 6 to
DN 100, for installations in buildings for potable water supply up to PN16 and a maximum distribution
temperature of 65 °C. Occasional excursions up to 90 °C are permitted for a period of 1 h maximum.
The ball valves are classified by their nominal pressure being either PN10 or PN16.
This document specifies:
— the requirements of the materials and the design of ball valves;
— the mechanical, hydraulic and acoustic requirements of ball valves;
— the test methods to verify the requirements of ball valves;
— the marking requirements of ball valves.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
ball valve
valve in which a ball, operated manually or via an actuator, rotates around an axis perpendicular to at
least one of the directions of flow; the ball has a hole where in open position the water will flow through,
in a straight or angled line
Note 1 to entry: Ball valves have a normal operating position of either fully open or fully closed. Ball valves will be
opened or closed by a single turn through 90°.
Note 2 to entry: The following types are covered:
— straight pattern ball valves;
— angle pattern ball valves;
— three way valves (1 inlet, 2 outlets).
3.2
nominal size
DN
nominal size of the ball valves is related to the size of the connection ends
Note 1 to entry: See Table 1.
Note 2 to entry: For valves provided with connection ends in different sizes, the nominal size (DN) of the smallest
connection end is leading and determines the minimum bore of the ball (Table 2 and Table 3).
4 Designation
The designation of a ball valve comprises:
— Design of the body (straight, angled or three way);
— type and material;
— nominal size (DN);
— bore (full or reduced);
— nominal pressure (PN);
— end connections;
— acoustic group (if applicable);
— number of this document, i.e. EN 13828.
EXAMPLE Straight pattern ball valve (S) of copper alloy, DN 25, PN 16, with threads Rp 1 on both sides,
acoustic group 1, according to EN 13828.
5 Design characteristics
5.1 Materials
5.1.1 General
All materials coming into contact with water intended for human consumption shall present no health
risk nor cause any change to the water in terms of quality, appearance, smell or taste.
NOTE While awaiting the adoption of verifiable European criteria for testing materials in contact with water
intended for human consumption, existing national regulations concerning the use and/or the characteristics of
these products remain in force.
5.1.2 Body materials
5.1.2.1 General
All parts of the body shall be made of a copper alloy or stainless steel.
5.1.2.2 Dezincification resistant copper alloy
Copper-zinc alloys containing more than 15 % zinc are subjected to dezincification when submitted to
water capable of dezincification. In the countries where the use of products made of dezincification
resistant materials is required, the materials used shall guarantee a dezincification depth less than
200 µm. For this purpose, materials shall be tested in accordance with EN ISO 6509-1 and the product
shall be marked in compliance with the indications according to Clause 9.
5.1.3 Corrosion resistance
The materials shall be corrosion resistant or protected against corrosion. The materials used shall not
have an adverse effect on each other.
When tested to the neutral salt spray (NSS) test according to EN ISO 9227 for a duration of (96 ± 1) h, no
corrosion which could impair the device’s operation shall be revealed by visual examination
(disregarding possible salt deposits). After the test, the valve shall not show any internal and/or external
leakage when being tested according 6.8.
5.1.4 Anti corrosive layer of the ball
Applied metallic anticorrosive protection layers shall fulfil the requirements of EN 248.
For this purpose, a separate ball shall be tested.
5.2 Connection ends
5.2.1 General
Connection ends shall comply with EN 1254 (all parts) with the exception of EN 1254-1 and EN 1254-4
(ends for capillary soldering or capillary brazing to copper tubes). Examples of connection ends are
shown in Table 1.
Valves with threaded connection ends shall have flats on the body which, when used for fitting, shall
accommodate commercially available tools.
The connection ends as applied shall be suitable (and approved as such) for the nominal pressure of the
valve.
