17、 Standard (EN 14802:2005) 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,
18、 at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. 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 st
19、andards 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, Germ

21、ope This European Standard specifies a method of testing the resistance of the upper assembly of inspection chambers and manhole components against surface and traffic loading. It does not include requirements for testing the cover and frame. These requirements are specified in EN 124 or other stand
22、ards depending on the material. NOTE 1 Upper assembly components would normally include riser shafts, tapers, reducing slabs and telescopic joints. NOTE 2 This test method is intended to support prEN 13598-2 and prEN 15229 (see bibliography) 2 Normative references The following referenced documents
23、are indispensable for the application of this European Standard. For dated references, only the edition cited applies.

30、ection chamber or manhole, is buried either in a soil box or under field conditions and a load is applied (see Figure 1). During loading, the vertical displacement of the cover assembly is measured. After the test is finished, the test assembly is visually inspected and checked for defects. NOTE The
31、 standard making reference to this European Standard can require test conditions that differ from those set in this European Standard for the following test parameters: a) the number of test pieces (see Clause 6); b) the maximum load (see Clause 9); c) the soil group of granular surround (see Clause
32、 9); d) the compaction of the granular surround (see Clause 9). 5 Apparatus 5.1 Soil box, large enough to accommodate at least the first 1 m of the test assembly and such that at all sides of the assembly a free space of 300 mm minimum is available. The box shall conform to the rigidity and other ge
33、neral requirements specified in EN 1437. 5.2 Loading device, capable of applying the required load to the middle of the cover and of maintaining a constant load for a minimum of 15 min. The load shall be applied via a loading plate conforming to the requirements given in EN 124. NOTE A loading devic
34、e could comprise a hydraulic actuator, alternatively the load can be applied using dead weight. 5.3 Thermo-couple, capable of measuring temperature to an accuracy of 5 C. 5.4 Test assembly, comprising at least the first 1 m of test assembly measured from and including the top assembly detail of the
35、inspection chamber or manhole (see Figure 1).

The test shall be performed at ambient temperatu
38、re between 5 C and 25 C. The test shall not be performed if the granular surround is at a temperature of less than 3 C. The temperature of the granular surround shall be recorded. 8 Procedure 8.1 Bury the test assembly (5.4) either in the soil box (5.1) or under field conditions using the test param
39、eters given in Table 1 ensuring that there is at least 300 mm of specified granular surround conforming to Clause 9. Where the test assembly is to be buried in the field, excavate enough soil to accommodate at least the first metre of the riser shaft below the test assembly. Bury the thermo-couple i
40、n the granular surround at the top of the riser shaft, but below the other assembly components, at a distance of approximately 300 mm. Where the inspection chamber or manhole incorporates a pavement as an integral part of the cover, apply the pavement as in real practice and bury under field conditi
41、ons. Where telescopic joints are supplied, install the support ring and covers in accordance with the manufacturers product or installation description.

42、 the distance between the top of the cover and a datum which will not be affected by the load see Figure 1b. 8.2 Apply the load using the loading device (5.2) within a period of 1 min to 5 min and maintain at the maximum value specified in Table 1 for a minimum of 15 min. Having applied the load re-
43、measure and record the distances between the top of the cover and the datum. 8.3 After removal of the load visually inspect the test assembly inspecting for cracks or defects likely to impair performance. 9 Test parameters Unless as otherwise specified in the referring system standard, the test para
