¶ Cstat
¶ purchaser maximum value (average or/and individual value); 2) purchaser minimum value
¶ Cdyn, 5 Hz or Cdyn 10 Hz
¶ purchaser maximum value (average or/and individual value). The supplier shall provide a reference value of bedding modulus for routine test, in the range of purchaser acceptance values. 5.3.3 Static and low frequency dynamic bedding modulus of USP alone with GBP The static and the low frequency dynamic bedding modulus of the USP alone with GBP allows the vertical bedding modulus of the USP to be quantified without the influence of a bonding system in concrete. This method requires a USP without a bonding system or with a bonding system which has no influence on the bedding modulus. The static and low frequency dynamic bedding modulus measured during the design approval tests shall determine the reference value of these bedding moduli to follow the quality of the production of USP during the routine tests NOTE 1 The values of bedding modulus with and without concrete block may be different. a) Test arrangement: The static and low frequency dynamic bedding modulus of USP alone with GBP shall be measured in accordance with Annex C. The low frequency dynamic bedding modulus is measured at (5 ± 1) Hz and (10 ± 1) Hz (and optional frequency tests at (20 ± 2) Hz and (30 ± 3) Hz). b) Design approval tests: The test method shall be applied on 3 USP alone. The supplier shall provide a reference value of bedding modulus for routine test, within the range of the results. NOTE 2 The bedding modulus with and without concrete block are not necessarily the same values. 5.3.4 Higher frequency dynamic bedding modulus of USP on concrete block This test evaluates the capacity of USP to insulate vibrations. a) Test arrangement: The higher frequency dynamic bedding modulus of USP on concrete block with GBP shall be measured in accordance with Annex H. The testing procedure and equipment are different to the determination of low frequency dynamic bedding modulus. NOTE 1 In contrast to the test of the low frequency dynamic bedding modulus Cdyn, the test procedure to measure the higher frequency dynamic bedding modulus CH is carried out with static preloading and with smaller vibration amplitude. For this reason the values of the two moduli are not the same when measured at the same frequency, e.g. at 20 Hz, CH (20 Hz)
² Cdyn (20 Hz). (see Figure 1). NOTE 2 The magnitude of the loss factor
of a USP influences the dynamic magnification in the region of the natural frequency of the elastically supported track as an oscillatory system. It determines the edge steepness of the amplitude response and thus the insertion loss of the overall system (see H.3). SIST EN 16730:2016

The purchaser shall define the evaluation criteria. 5.3.5 Fatigue test of USP on concrete block This test evaluates the durability of USP in contact with ballast. This fatigue test permits the evaluation of the interaction of the ballast with USP. a) Test arrangement: The fatigue test of the USP on concrete block shall be carried out in accordance with Annex D. b) Design approval tests: The test method shall be applied on one USP on concrete block. Visual inspection shall be according to the purchaser's criteria. 5.3.6 Fatigue test of USP on concrete block with GBP This test evaluates the durability, stability of bedding modulus and vibration characteristics (in case of use for vibration applications) of USP in contact with GBP. This test permits the evaluation of the long term variation of bedding modulus of USP. SIST EN 16730:2016

¶ purchaser value. 5.3.7 Capability for stacked stocking of sleepers with USP, testing by USP on a concrete block This test permits the impact on the USP when stacked in storage to be quantified. a) Test arrangement: The capability for stacked stocking of USP shall be measured in accordance with Annex J. The purchaser defines the test pressure ptest. Example of calculation of ptest: ptest = (safety coefficient) x 0,8 N/mm2 (15 sleepers of 3 000 N each on two wood battens with a contact section with USP of 280 mm x 100 mm ≥ 0,8 N/mm2). NOTE Safety coefficient is between 1 and 1,2 depending on rail seat inclination and size of battens. The USP manufacturer chooses the test pressure ptest. Results are valid for all the values less or equal to the test load. b) Design approval tests: The test method shall be applied on one USP on concrete block. Visual inspection shall be according to the purchaser criteria. The purchaser shall define the evaluation criteria in the list: 1) Cstat
¶ purchaser value; 2) Cdyn 5 Hz
¶ purchaser value; 3) variation of thickness of the USP
¶ purchaser value. 5.3.8 Effect of severe environmental conditions on USP on concrete block This test evaluates the durability of sleepers with USP with respect to the cycles of the seasons. This effect of severe environmental conditions test shall quantify the effects of the seasons on USP. The variations of static and the low frequency dynamic bedding modulus of USP on concrete block with GBP are measured in accordance with Annex C in order to quantify the variation of bedding modulus characteristics after the effect of severe environmental conditions of USP on concrete block. SIST EN 16730:2016

· purchaser average value; 3) minimum value of at least 3 pull-out tests
· purchaser minimum value. 5.3.9 Resistance to other environmental parameters The chemical agents used for the production of the USP should not modify the properties of the sleepers or bearers. The purchaser shall define test methods. Water, Hydrocarbons and Ozone (in track) shall not modify significantly the material characteristics of USP. The test is performed with the supplier’s instructions which are approved by the purchaser. In case of fire the USP should not propagate the fire or create toxic fumes. The purchaser shall define test methods. The requirements can be different for tunnel, station or open track. The purchaser shall define the evaluation criteria and the number of samples for: 1) resistance to chemical agents related to the manufacture of sleepers or bearers; 2) resistance to water (hydrolysis); 3) resistance to hydrocarbon; 4) resistance to ozone; 5) resistance to fire. 5.4 Tests of concrete sleepers and bearers without USP The sleeper or bearer shall fulfil the requirements given in the EN 13230 series. The purchaser shall define performances of concrete sleepers or bearers used. 5.5 Tests of USP on concrete sleepers and bearers 5.5.1 Dimensions and masses of sleepers and bearers with USP Dimension of the USP shall fit to the dimensions of the concrete sleeper/bearer bottom surface. USP may cover the whole or part of the bottom surface of the sleeper or bearer. USP geometry and position at sleeper bottom surface shall take into account events during lifetime:
