    28、g equipment shall be deemed to comply with the requirements specified in 4.1, if the values of gas pressure and gas flow do not deviate by more than 1,5 % (Class A) and 5 % (Class B) from the set points over a 20 min period of spraying. 5.3 Flame spraying nozzle Nozzles shall be deemed to comply wit

    29、h the requirements specified in 4.2 if, after continuous spraying of nozzle- compatible materials at the maximum spray rate specified by the manufacturer for a period of 20 min, no disturbing deposits of spraying material have been built up. 5.4 Equipment specific tests 5.4.1 Spraying with liquid fu

    30、el HVOF flame spraying equipment shall be deemed to comply with the requirements specified in 4.1 if the values of liquid fuel pressure and flow rate do not deviate by more than 2 % (Class A) and 5 % (Class B), from the set points over a 20 min period of spraying. 5.4.2 Wire flame spraying The suita

    31、bility of the system to process wires shall be tested with the flame burning; the length of wire fed in 1 min shall be measured. This determination shall be repeated twice more. The variations in fed length shall not exceed 5 %. For this test, wire materials and wire diameters for which the system i

    32、s designed shall be used. 5.4.3 Flame spraying using rods or cords Testing shall be carried out for 1 min1 using Al 2 O 3rods or cords of the agreed diameter. 5.4.4 Powder flame spraying The suitability of the system to process powders applying a stand-alone as well as a burner integrated powder fee

    33、d unit shall be tested according to EN 1395-7. 5.5 Backfire of flame Backfire of the fuel gas/oxygen flame shall not occur if the spraying equipment is operated according to the manufacturers instructions.
