This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 393.

If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations which
stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other language
made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management
Centre has the same status as the official versions.

Foreword
This document (prEN 13160-5:2011) has been prepared by Technical Committee CEN/TC 393 “Equipment for
storage tanks and for filling stations”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13160-5:2004.
This European Standard, EN 13160, Leak detection systems, consists of seven parts:
 Part 1: General principles
 Part 2: Pressure and vacuum systems
 Part 3: Liquid systems for tanks
 Part 4: Liquid and/or vapour sensor systems for use in leakage containments or interstitial spaces
 Part 5: Tank gauge leak detection systems
 Part 6: Sensors in monitoring wells
 Part 7: General requirements and test methods for interstitial spaces, leak protecting linings and leak
protecting jackets
According to EN 13160-5:2004 the following fundamental changes are given:
 a new category for static leak detection systems and the appropriate leak rate for test added.

4 General
General principles shall be according to prEN 13160-1.
Tank gauge leak detection systems shall be divided into two categories of operation:
 Category A: Systems providing leak detection for tanks and pipes, connected with the tank;
 Category B: Systems providing leak detection for tanks only.
The minimum operational performance requirements for each category are contained in Table 1.
