21、n-fuel), used in spray jobs to produce thermally sprayed coatings of reproducible quality. This part should be used in conjunction with EN 1395-1, which includes general requirements and explanations of procedures. 2 Normative references The following referenced documents are indispensable for the a

23、thermal spraying equipment Part 7: Powder feed systems 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 657:2005 apply. 4 Principles of acceptance inspection 4.1 General The following clauses reveal state of the art technology in thermal spraying equip
24、ment and the minimum requirements concerning a stable parameter setting and maintenance according to the classes given in Annex A or Annex B. 4.2 Flame spraying nozzle Processing the spraying material shall be possible without any visible disturbing deposits on the burner nozzle and/or air nozzle. 4
25、.3 Spraying material feed unit The material feed unit shall be suitable for operation along with the spraying equipment to be tested. The unit shall permit uniform processing of the consumables for which it is designed. It shall be possible to adjust the spraying material feed rate. The set points s
26、hall be constant and reproducible, a precondition for this being adequate and constant carrier gas pressure or actuating air pressure or supply of electrical power as appropriate.

27、E) 5 5 Procedure of acceptance inspection 5.1 General Spraying equipment shall be deemed properly supplied for all suitable spraying applications and for use with all suitable spraying materials required for the spraying process if it complies with the following requirements: 5.2 Gases Flame sprayin
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.
