Overview

EN 15069:2008 (CEN) specifies requirements and test methods for safety gas connection valves (SC valves) used on metal hose assemblies for connecting domestic appliances to the fixed gas supply. The standard covers valves for use with 2nd and 3rd family gases at pressures up to and including 0.5 bar, and addresses both movable and fixed domestic appliances. EN 15069 defines construction, performance, testing and conformity assessment necessary to ensure safe, reliable gas connections in household installations.

Key topics and technical requirements

The standard addresses the full product lifecycle from design to conformity, including:

• Scope & classification
  • Valve types and temperature and pressure classes relevant to domestic gas applications.
• Construction & materials
  • Requirements for materials, nominal sizes, connections and operation (including manual controls and quick-connect designs).
• Performance tests
  • Comprehensive test schedule covering: leak-tightness (internal, external, angular), internal pressure testing, rated flow-rate, tensile, bending and torsion resistance, and impact.
• Durability & environmental resistance
  • Durability cycles for manual controls and connection/disconnection, thermal ageing, high/low temperature resistance, resistance to lubricants and corrosion.
• Safety-specific checks
  • Overflow and stop resistance, electrical continuity, reaction to fire and resistance to gas.
• Conformity & quality control
  • Type testing (initial and subsequent), Factory Production Control (FPC) requirements, installation instructions, and packaging.
• Informative annexes
  • Design guidance for connections to pipework/portable gas bottles, and test end fitting details (Annex A, B) plus a clause-to-directive mapping (Annex ZA).

Applications

EN 15069 is directly applicable to:

• Manufacturers of safety gas connection valves and metal hose assemblies designing products for domestic gas appliances.
• Test laboratories performing type and routine tests (leakage, pressure, mechanical strength).
• Certification bodies and notified bodies assessing conformity to European requirements.
• Gas installers and specifiers selecting compliant connection valves for cookers, heaters and other household gas appliances.
• Regulators and safety authorities referencing harmonized product requirements for consumer safety.

Who should use this standard

• Product designers and R&D teams for gas fittings
• Quality managers implementing Factory Production Control (FPC)
• Test engineers and conformity assessors
• Installers and procurement officers sourcing compliant valves

Introduction
This European Standard contains product characteristics relating to the safety of persons, animal and property
and the protection of their environment.
The objective of this European Standard is to achieve safe operation of connection valves by specifying the
requirements of performance, materials and test methods.
Safety gas connection valves are used internally to connect gas appliances including movable gas appliances
and externally to connect appliances such as grills, gas radiation heating, lights etc.
Valves manufactured to this European Standard are designed to be used with compatible hose assemblies
conforming to EN 14800 and prEN 15070:2007.
Attention is drawn to the need for careful quality control as given in EN ISO 9001:2000.
This European Standard is based on a balance of requirements given by the major national European Gas
Authorities for valves and metal hose assemblies for the connection of domestic gas appliances.
It reflects the recognised practise and technology of products approved today as well as the present culture of
usage by the consumer.
The introduction of new technologies supported by National Gas Authorities may require the adoption of this
European Standard regarding individual requirements and tests.

5.4 Leak-tightness
5.4.1 Angular seal
5.4.1.1 Requirements
With the SC valve in the fully closed position, the angular distance between the gas port in the closure
member and both the inlet port and outlet port in the SC valve body, shall be at least 8º with a measurement
uncertainty of 1º.
5.4.1.2 Test
The procedure shall be as follows. Install the SC valve on a test rig which shall be capable of measuring the
angle of rotation of the actuator (e.g. a 360º graduated scaled pointer fixed to the actuator).
Connect the SC valve inlet to an air source at a pressure of 1,5 MOP.
Close the SC valve. Open the SC valve until the internal leakage is greater than what is required in 5.4.3. The
value measured shall satisfy the requirements of 5.4.1.1.
A bubble indicator or a similar flow measuring device shall be used to check that the flow has ceased.
5.4.2 External leak-tightness
5.4.2.1 Requirements
In either connected or unconnected position, the external leak-tightness of the SC valve shall be less than or
equal to 15 cm /h.
5.4.2.2 Tests
5.4.2.2.1 General
The tests shall be carried out in the direction of the normal flow of gas with the following test pressure:
 Pe 1 = 20 mbar;
 Pe 2 = 1,5 MOP.
The inaccuracy of the measurement shall not be greater than 4 cm³/h and the resolution shall be greater than
/h.
1 cm
5.4.2.2.2 Test in a connected position
The test shall be carried out with the closed test end fitting connected to the SC valve.
In a case where an OSD can be manually operated and there is an independent manually operated control, it
shall be successively set to the fully open, intermediate and fully closed position. The leakage rate shall be
measured for Pe1 and Pe2.
5.4.2.2.3 Test in an unconnected position
Prior to the test the SC valve shall be in a connected position and pressurised.
The SC valve shall then be disconnected and after 2 s the leakage rate shall be measured.
In cases where there is an independent manually operated control, it is successively set to the fully open,
intermediate and fully closed position.
The leakage rate shall be measured for 1,5 MOP.
5.4.3 Internal leak-tightness
5.4.3.1 Requirements
This requirement shall only apply to SC valves equipped with manually operated control.
In the connected position, the internal leak-tightness shall be less than or equal to 15 cm³/h.
5.4.3.2 Test
This test shall be carried out on samples n° 1 and n° 2 with suitable equipment giving the accuracies stated
below. The test shall be carried out in the direction of the normal flow of gas with air at the following test
pressure:
 Pe = 20 mbar;
 Pe = 1,5 MOP.
The inaccuracy of the measurement shall not be greater than 5 cm³/h and the resolution shall be greater than
1 cm /h.
The open test end fitting shall be connected to the unit and the manual control shall be set to fully closed.
The leakage rate shall be measured for pressure Pe1and Pe2.
5.5 Internal Pressure
5.5.1 Requirements
In either connected or unconnected position, the internal pressure test for a safety gas connection SC valve
shall be deemed to be satisfactory if after meeting the requirements of 5.5.2 the value of the leak measured
shall be less than or equal to 15 cm /h. The appropriate strength test pressure according to Table 5 shall be
maintained for at least 5 min.
Table 5 — Strength test pressure (STP) as a function of the maximum operating pressure (MOP)
MOP STP
bar bar
0,1 < MOP ≤ 0,5 > 1,75 MOP
MOP ≤ 0,1 ≥ 2,5 MOP
5.5.2 Test
The internal pressure test shall be carried out using air.
The appropriate strength test pressure according to Table 5 shall be maintained for at least 5 min.
The internal pressure test shall precede or be performed simultaneously with the tightness test.
