Directive of the European Parliament and of the Council of 12 December 2006 laying down technical requirements for inland waterway vessels and repealing Council Directive 82/714/EEC (2006/87/EC) (repealed)

Article 14.14 Tests

Tests on the installation shall be carried out under the following conditions:

1.

Medium-pressure pipes between the closing device, referred to in Article 14.09 (4), of the first pressure regulator and the valves fitted before the final pressure regulator:

(a)

pressure test, carried out with air, an inert gas or a liquid at a pressure 20 bar above atmospheric pressure;

(b)

tightness test, carried out with air or an inert gas at a pressure 3,5 bar above atmospheric pressure.

2.

Pipes at the service pressure between the closing device, referred to in Article 14.09(4), of the only pressure regulator or the final pressure regulator and the valves fitted before the gas-consuming appliances:

• tightness test, carried out with air or an inert gas at a pressure of 1 bar above atmospheric pressure.

3.

Pipes situated between the closing device, referred to in Article 14.09 (4), of the only pressure regulator or the final pressure regulator and the controls of gas-consuming appliances:

• tightness test at a pressure of 0,15 bar above atmospheric pressure.

4.

In the tests referred to in paragraphs 1(b), 2 and 3, the pipes are deemed gastight if, after sufficient time to allow for equalisation with ambient temperature, no decrease in the test pressure is observed during a further 10 minute test period.

5.

Receptacle connectors, pipe joints and other fittings subjected to the pressure in the receptacles, and joints between pressure regulators and the distribution pipe:

• tightness test, carried out with a foaming substance, at the service pressure.

6.

All gas-consuming appliances shall be brought into service at the nominal capacity and shall be tested for satisfactory and undisturbed combustion at different capacity settings.

Flame failure devices shall be checked to ensure that they operate satisfactorily.

7.

After the test referred to in paragraph 6, it shall be verified for each gas-consuming appliance connected to a flue, whether, after five minutes' operation at the nominal capacity, with windows and doors closed and the ventilation devices in operation, any combustion gases are escaping into the room through the air intake.

If there is a more than momentary escape of such gases, the cause shall immediately be detected and remedied. The appliance shall not be approved for use until all defects have been eliminated.
