NOTE For the granular media filter, the filtration surface area to be taken into account is that of the inside horizontal cross section of the filter vessel, generally taken at 2/3rd of its height. For the other types of filter, the total functional developed surface area of the support (unfolded) is taken into account. 4.3 Filter media 4.3.1 General If the filter medium being used is covered by an existing European standard this standard shall be applied. NOTE See Bibliography. 4.3.2 Granular media In general, dealing with granular filter media, the type of filter media and height of filter media within the filter are some of the main aspects, which are expected to be supplied by the manufacturer. The specification of the media shall include: SIST EN 16713-1:2016

Close the valve 7 and the solenoid valves 5 and 6 and adjust the valve 4 until the pressure in the test filter body reaches its MOP ± 10 kPa (±0,1 bar) or any other value specified by the manufacturer; f) Adjust the solenoid valves 5 and 6 so as to obtain the pressure wave shape indicated in Figure 3. Adjust the valve 7 so as to obtain a pressure differential of 10 kPa to 20 kPa to avoid the negative pulses of the outlet pressure; g) Reset the counter 9 to zero; SIST EN 16713-1:2016

The burst pressure of the test filter is that measured in 5.4.1 for which a leak was observed on the test filter. 5.4.3 Test report In addition to a reference to this document, the test report shall include the following information: — name of the testing laboratory; — operator name; — test date; — person responsible for placing the product on the market; — product code and/or reference; — test temperature; — specified pressure (1,5 × MOP or any other pressure specified); SIST EN 16713-1:2016
