EN 14830:2006 (E) 3 Foreword This European Standard (EN 14830:2006) has been prepared by Technical Committee
CEN/TC 155 ”Plastics piping systems and ducting systems”, the secretariat of which is held by NEN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2007, and conflicting national standards shall be withdrawn at the latest by April 2007. The relevant performance requirements are contained within the referring standard(s) concerned. This European Standard is one of a series of standards on test methods that support System Standards for plastics piping systems and ducting systems. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14830:2006 (E) 4 1 Scope This European Standard specifies methods of test for the resistance of the base of thermoplastics inspection chambers and manholes to external soil and ground-water pressure after installation. NOTE
This is intended as a test of the durability and structural integrity of manhole and inspection chamber bases supporting product standards prEN 13598-2 [1] and prEN 15229 [2]. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ENV 1046:2001,
Plastics piping and ducting systems  Systems outside building structures for the conveyance of water or sewage  Practices for installation above and below ground EN ISO 9967:1995,
Thermoplastics pipes  Determination of creep ratio (ISO 9967:1994) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 inspection chamber drainage or sewerage fitting used for the to connection of drainage or sewerage installations and/or for changing the direction of drainage or sewerage runs. An inspection chamber terminates at ground level, permitting the introduction of cleaning, inspection and test equipment and the removal of debris but it does not provide access for personnel. The riser shaft connected to these fittings has a minimum outer diameter of 200 mm and a maximum inside diameter of less than 800 mm (see also EN 476:1997 [3] for non circular chambers) NOTE The termination at ground level permits the introduction of cleaning, inspection and test equipment and the removal of debris but does not provide access for personnel. 3.2 manhole drainage or sewerage fitting used for the connection of drainage or sewerage installations and/or for changing the direction of drainage or sewerage runs. A manhole terminates at ground level, permitting the introduction of cleaning, inspection and test equipment and the removal of debris and also providing access for personnel. The minimum inside diameter of a manhole riser shaft is 800 mm (see also EN 476:1997 [3] for non circular manholes) NOTE The termination at ground level permits the introduction of cleaning, inspection and test equipment and the removal of debris and provides access for personnel. 4 Principle A sealed test assembly comprising an inspection chamber or manhole base with a minimum height of 300 mm above the top of the main channel, is placed free standing, or buried in a test box on a 100 mm sand or granular bed and covered with granular backfill to a level of minimum 300 mm above the top of the outlets and inlets of the main channel(s). In some cases the first section of the riser may be required in order to achieve the minimum height of 300 mm.



EN 14830:2006 (E) 5 The assembly is then subjected to a constant internal negative pressure, specified by the product or system standard, for a specified time at a temperature of between 15 °C and 25 °C or as otherwise specified in the product standard. Alternatively, the pressure difference can be achieved by exposing the test assembly to a constant positive external hydrostatic pressure of the same numeric value as that specified by the product or system standard. The assembly is submerged under water in a closed tank for a specified time at a temperature of between 15 °C and 25 °C or as otherwise specified in the product standard. During the test the assembly may be monitored by measuring increasing deflections with time as defined in the product standard. At the end of the test the chamber base/manhole is visually checked for cracking or other defects likely to impair the performance of the inspection chamber or manhole. 5 Apparatus 5.1 Test box, large enough to accommodate the test assembly including the first 300 mm of riser shaft above the top of the outlet and inlets of the main channel, such that at each side there is a fr
