27、ing to EN 13160-1. Where the requirement is for low temperature performance the alternative test temperature is shown in brackets . Liquid or vapour sensors shall be installed in such a way that they can detect specific liquids or their vapours present in or entering the leakage containment or inter
28、stitial space. The leakage containment can take the form of a ? sump or riser containing spills from leaks in double wall lines or pumps; ? bund, designed to contain leakage from a storage tank or from any other facility containing liquids; ? other facilities in which sensors can be installed to det
29、ect the presence of liquids or vapours. 5 Interstitial space General requirements concerning the interstitial space according to EN 131607. The design of the interstitial space intended to detect liquid shall allow detection of a minimum amount of 10 l of a specific liquid present in or entering the
30、 interstitial space. The interstitial space shall allow an installation of the sensor at the deepest point of the interstitial space. The interstitial space shall be constructed so that the leakage liquid shall reach the deepest point of the interstitial space. For a tank, the system shall be design
31、ed so that there are no connections to the inner tank through the interstitial space, below the maximum filling level. For a pipe, the system shall be designed so that there are no connections to the inner pipe through the interstitial space. The interstitial space shall be capable of being tested f
32、or integrity. 6 Leakage containment The design of leakage containment intended to detect liquid shall allow detection of a minimum amount of 10 l of a specific liquid present in or entering the containment. The number of sensors of the system shall correspond to the intended number of low points in
33、the leakage containment. NOTEThe design of a leakage containment should allow that liquid leaking from any point in the primary system will collect in at least one of a number of low points in the leakage containment. The leakage containment shall be liquid tight and impervious to the stored product
34、, water or any other substance with which it is likely to come into contact, and shall have no outlets below the level of the maximum contained volume. If protection against ingress of water is not possible, technical measures have to be taken to avoid impairment of the function of the leak detector

It shall be possible to test
36、the leakage containment for leaks. If the leakage containment is used as a bund for a primary system holding liquids then the walls of the bund shall fully surround the system and shall be capable of containing the entire contents of the primary system. 7 Liquid sensor Liquid sensors shall detect sp
37、ecific liquids they can normally come into contact with (e. g. stored product, water). Liquid sensors shall comply with the test criteria according to clauses 10 or 11, as appropriate. 8 Vapour sensor Vapour sensors shall detect specific vapours from stored products. Vapour sensors shall comply with
38、 the test criteria according to clause 12. 9 Leak indicating device A leak indicating device shall be provided. An alarm shall indicate when the presence of stored product and/or water is detected. 10 Type test of the liquid sensors 10.1 Test objective The aim of the test is to verify the suitabilit
39、y of a sensor system to detect the ingress of liquid into the interstitial space or leakage containment, where this space is normally dry. Tests shall be performed to verify: ? the response time of the sensor system in indicating the presence of liquid, where the liquid level is rising at a given ra
40、te; ? the recovery time of the sensor system from a liquid-indicating condition following its removal from the presence of liquid. A sensor system shall be qualified for use with each type of liquid that it shall be required to detect. Where possible, tests shall be performed using these actual liqu
41、ids, however where significant hazards may result, a less harmful test liquid may be used having similar chemical and physical properties. For example, a substitute for petroleum spirit would be petroleum naphtha (an aliphatic petroleum distillate). 10.2 Evaluation Tests shall be deemed to have been
42、 passed where: ? the presence of liquids is not indicated when no liquid is present; ? the presence of liquid is indicated within 30 min after liquid is first introduced into the test system at the rate of 10 l/h; ? the presence of liquid is indicated within 6 min after liquid is first introduced in
43、to the test system at the rate of 50 l/h; Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 09:56:36 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13160-4:2003 (E) 6 ? the sensor has a measurable recovery time of max 20 h after removal of the test liquid. These criteria shall be satisfied over
44、the range of environmental conditions specified in the test in 10.4. The system shall remain in the alarm condition until the sensor has recovered and the alarm has been reset. 10.3 Test equipment A test vessel in the form of a flat-bottomed vertical cylinder, having a horizontal cross-sectional are
45、a of (0,1 0,002) m2 (i.e. a liquid depth of 0,01 m corresponds to a volume of 1 l) and a minimum depth of 0,6 m. One or more fittings flush with the inside surface of the vessel shall be provided in the floor of the vessel for the introduction of liquids. A similar fitting shall be provided having a
46、 drain cock capable of emptying the vessel at a rate of 5 l/min. Suitable quantities of each liquid for qualification (or suitable test liquids). A calibrated metering pump (with a reservoir of minimum 6 l capacity) capable of delivering liquid into the test vessel, at the rates specified in 10.2, w
47、ith an accuracy of 2 %. An environmental chamber the temperature of which can be varied over the range from - 25 ?C to + 70 ?C with an accuracy of 2 K. For the test in a temperature range from 40 C to + 40 C an environmental chamber the temperature of which can be varied over a range from 50 C to +
48、40 C with an accuracy of 2 K. A stop clock having a time indication in steps of 1 s to a minimum total of 24 h, with an accuracy of 2 s. 10.4 Test method 10.4.1Preparation The sensor under test shall befixed in its normal orientation ensuring contact with the floor of the test vessel but away from a
49、ny ports for the entry or extraction of liquid. The manufacturers fittings should be used wherever possible. The test vessel and metering pump reservoir shall be mounted inside the environmental chamber. The sensor under test shall be connected to the leak indicating device which shall be mounted outside the environmental chamber in ambient laboratory conditions. Prior to the series of tests for each liquid for which the sensor system shall be qualified, the metering p
