20、ciples of acceptance inspection 4.1 General The following clauses reveal state of the art technology in thermal spraying equipment and the minimum requirements concerning a stable parameter setting and maintenance as given in Annex A. 4.2 Atomising gas The atomising gas hoses and the control device

21、shall be designed in such a manner that an undisturbed operation is ensured. 4.3 Arc spraying nozzle The nozzle system (contact tubes and air nozzle) shall permit a constant arc to be maintained and provide atomisation without causing deposits that might disturb the operation. 4.4 Spraying wire feed

22、 unit A continuously controllable and reproducible feed of the wires shall be provided. A precondition for this is an adequate constant air pressure and supply of electrical power.

23、roperly 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 Electrical power and wire feed unit Proof of the power rating required for continuous operation and of compli

24、ance of the feed unit with the requirements as specified in 4.4 shall be deemed to have been provided if: no deviations of the adjusted electrical values of more than 5 % or other disturbances due to an increased thermal loading occur; and system is operating at a maximum capacity for 10 min with a

25、coating material with a suitable diameter: 1) anti-corrosion arc spraying system: zinc aluminium alloy, thermal spray material according to EN ISO 14919:2001, 2.3, or 2) engineering application arc spraying system: pure copper, thermal spray material according to EN ISO 14919:2001, 4.1. 5.3 Atomisin

26、g gas The equipment shall be deemed to comply with the requirements of 4.2 if the atomising gas pressure indication does not deviate by more than 5 % from the set point over a 10 min period of spraying. 5.4 Arc spraying nozzle The nozzle system shall be deemed to comply with the requirements given i

27、n 4.3 if, after testing according to 4.4, no disturbances occur in the arc and no disturbing deposits have been built up on the nozzle system by more or less molten spraying material. 6 Designation Acceptance inspection of the thermal spraying equipment for arc spraying shall be designated as follow
