Petrol filling stations - Part 2: Safety requirements for construction and performance of safe breaks for use on metering pumps and dispensers

This European Standard specifies safety requirements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at filling stations and used to dispense liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l min-1.
The requirements apply to safe breaks at ambient temperatures from –20 °C to +40 °C with the possibility for an extended temperature range.
It pays particular attention to electrical, mechanical and hydraulic characteristics of, and electrical apparatus incorporated within or mounted on, the safe break.
This European Standard applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This European Standard also addresses electrical and mechanical hazards.
NOTE 1   This European Standard does not apply to equipment for use with liquefied petroleum gas (LPG) or liquefied natural gas (LNG) or compressed natural gas (CNG).
NOTE 2   Fuels other than of Explosion Group IIA are excluded from this European Standard.

rights of which they are aware and to provide supporting documentation.

This document has been prepared under a mandate given to CEN by the European Commission and the

European Free Trade Association, and supports essential requirements of EU Directive(s).

For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this

document.

8 Overview of tests
Tests shall be performed in accordance with Table 4.

NOTE Pneumatic testing is potentially a much more dangerous operation than hydraulic testing.

Type tests are those tests required to evaluate conformity. Four safe breaks shall each be subjected to

the type tests as set out below.

All fuel safe breaks for type test shall be pre-conditioned according to B.2 and B.3.

All aqueous urea solution safe breaks for type test shall be pre-conditioned according to B.3.

For fuel safe breaks, the preconditioning mechanical impact test according to B.3 shall be done

immediately after removal from saturated atmosphere and shall be commenced within 30 min of

removal from saturated atmosphere. Tests B.4, B.5, B.7 to B.16 shall then be performed without delay

and shall be completed within 6 h of the commencement of the pressure test and finally in accordance

with B.6.

9 Information for use
9.1 General
Information for use shall be according to prEN 13617-1:2018.
9.2 Marking and instruction

If the size of the safe breaks is not large enough for the marking, then marking shall be in accordance

with EN 60079-0.

Safe breaks shall be marked legibly and indelibly during the manufacturing process; where necessary

this marking may be made visible for inspection by the easy removal of plastic covers. Marking shall

include at least the following information:
— manufacturer's name or identification;
— manufacturer’s type indication;

— the ambient temperature range if it is outside the temperature range of −20 °C to +40 °C;

— serial number, batch code or date code with a precision of at least year and quarter;

— direction of flow; if necessary.
— EN-number;

Instructions shall be included for re-usable safe breaks, and concerning the maximum flow rate.

Instructions shall be provided by the manufacturer for the safe installation, operation and maintenance

of the safe break.

(normative)
General requirements of test
A.1 General
All pressures shall be gauge (over pressure) readings.
All tests shall be carried out at (20 ± 5) °C unless otherwise noted.

All tests shall be carried out using a test liquid according to B.1 unless otherwise noted.

A.2 Tightness test 1
A.2.1 To determine whether the safe break does not leak.
+10 +0,1
0 0

A.2.2 The fully assembled safe break shall be tested with a pressure of (525 ) kPa [( 5,25 5) bar],

the pressure shall be maintained for not less than (10 ) s.

A.2.3 During the (10 ) s of the applied pressure observe for leakage and record results.

A.2.4 The pressure shall be reduced to 0 Pa [0 bar].

A.2.5 Alternatively to this test, for instance a pressure differential test, may be applied provided the

results are comparable to those achieved by this test.
A.3 Pressure separation test 1

A.3.1 To determine whether the safe break does not separate under a stated applied pressure.

+10 +0,1
0 0

A.3.2 The fully assembled safe break shall be tested with a pressure of (525 ) kPa [(5, 25 ) bar],

the pressure shall be maintained for not less than (10 ) s.
A.3.3 Observe and record the state of the safe break.

A.3.4 Alternatively to this test, for instance the application of an external pulling force identical to the

+10 +0,1
0 0

internal force created by a liquid pressure of (525 ) kPa [( 5, 25 ) bar], where this does not

exceed 650 N, may be applied provided the results are comparable to those achieved by this test.

Tests
B.1 Test liquid

Where a test liquid is required for the testing of fuel safe breaks, it shall be an odourless kerosene

except where otherwise noted. Water, or a mixture of water and glycol up to 15 % by volume, shall be

used for the testing of aqueous urea solution safe breaks except where otherwise noted.
