23、r vapour sensor systems for use in leakage containments or interstitial spaces EN 60529:1991, Degrees of protection provided by enclosures (IP Code) (IEC 60529:1989) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13160-1:2016 apply. 4 General This ty

24、pe of leak detection kit is classified according to EN 13160-1:2016 as class V. The general requirements on leak detection systems according to Clause 5 of EN 13160-1:2016 shall be met. 5 Monitoring wells Monitoring wells shall be installed in the ground, with a minimum diameter of 300 mm. Where liq

25、uid sensors are used, the monitoring well shall extend from the ground level to a depth of at least 1,0 m below: a) the lowest normal groundwater level or b) the lowest point of any tank or pipe, whichever is lower. Where vapour sensors are used, the monitoring well shall extend from the ground leve

26、l to a depth of at least 1,0 m below the lowest point of any tank or pipe. Where there is the risk that the normal groundwater level will fall below the point 1,0 m above the lowest perforation opening of a monitoring well, vapour sensors shall be used. Shall have a casing which is perforated unifor

27、mly, both vertically and circumferentially, which extends from ground level to the lowest point of the well. The pattern of perforations shall be designed to permit entry of liquid into the well at any height, but shall be small enough to prevent inflow of the surrounding ground material. DIN EN 131

28、60-6:2016-12 EN 13160-6:2016 (E) 5 The casing should be constructed with sufficient strength so that the well is not distorted under pressure of the surrounding ground, whether empty or full of liquid. Shall have a top cap sealed to a minimum standard of IP 66 according to EN 60529:1991, to prevent

29、entry into the well of surface water, liquid spills etc. The cap shall be removable to allow inspection of the contents of the well. Shall have a bottom seal fixed permanently to the casing to prevent the entry of ground material during installation or in service. Sufficient monitoring wells should

30、be installed around a system and positioned to ensure that any leakage of stored product from any part of the system will reach a monitoring well. Specification for the monitoring well casing: Size: minimum 100 mm inner diameter Wall thickness: minimum 6,0 mm Material: e.g. Polyethylene (PE) or equi

31、valent Slots: 0,4 to 0,6 mm wide 45 to 55 mm long equally spaced around the circumference of the casing 6,8 mm vertical spacing. The casing shall be closed at the bottom. In ground conditions where fine soil is present that would pass through the slots a filter screen should be fitted of such size a

32、s to prevent passage of the ground material. Monitoring wells should not be used where the ground material does not allow adequate permeation of stored product or vapour between the storage system and the monitoring well. Monitoring wells should be surrounded by filler sand or pea shingle to at leas

33、t 300 mm diameter. Construction of a monitoring well, see Figure 1.

35、 4.2.1 and 4.2.2 of EN 131604:2016. Shall be capable of differentiating between water and the stored product, and shall not give an alarm condition in the presence only of water. If the liquid sensor requires the presence of groundwater for correct operation, and the level of groundwater falls below

36、 the minimum or rises above the maximum necessary for correct operation, an alarm condition shall result. DIN EN 13160-6:2016-12 EN 13160-6:2016 (E) 7 7 Vapour sensor The vapour sensor shall meet the requirements according to 4.1.2 to 4.1.4, if applicable and 4.1.5, 4.2.1 and 4.2.2 of EN 131604:2016

37、. The alarm device shall enter an alarm condition in the presence of vapour of the stored product. Vapour sensors used in any location where there is the risk that they could become submerged in water or any other liquid shall sound an alarm on becoming submerged. 8 Alarm device An alarm shall be indicated on detecting the presence of stored product or on detecting the absence of water, when this is required for correct operation. An alarm device according to EN 13160-3:2016, 4.1.3.5 shall be provided. DIN EN 13160-6:2016-12
