This

15、 European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2007, and conflicting national standards shall be withdrawn at the latest by July 2007. This document together with EN 1395-1, 1395-2, 1395-4, 1395

16、-5, 1395-6 and 1395-7 supersedes EN 1395:1996. EN 1395 consists of the following Parts, under the general title Thermal spraying Acceptance inspection of thermal spraying equipment: Part 1: General requirements; Part 2: Flame spraying including HVOF; Part 3: Arc spraying; Part 4: Plasma spraying; Pa

17、rt 5: Plasma spraying in chambers; Part 6: Manipulator systems; Part 7: Powder feed systems. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Rep

20、ase arc spraying, used 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 applic

21、ation of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 657:2005, Thermal spraying Terminology, classification EN ISO 14919:2001, Thermal spraying Wires, rods and cords

22、for flame and arc spraying Classification Technical supply conditions (ISO 14919:2001) 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 tech

23、nology 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 shall be designed in such a manner that an undisturbed operation is ensured. 4.3 Arc spraying

24、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 unit A continuously controllable and reproducible feed of the wires shall be provided. A prec

25、ondition for this is an adequate constant air pressure and supply of electrical power. This standard may only be used and printed by approved subscription and freemailing clients of the SABS.EN 1395-3:2007 (E) 5 5 Procedure of acceptance inspection 5.1 General Spraying equipment shall be deemed to h

26、ave been 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 Electrical power and wire feed unit Proof of the power rating required for continuous operation and

27、 of compliance 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 m

28、in with a 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.

29、3 Atomising 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 requiremen

30、ts given in 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
