15、t of which is held by DIN. This 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of an identical text or by endorsement, at the latest by July 2007, and conflicting national standards shall be withdrawn at the latest by July 2007.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

16、 EN 1395-2, 1395-3, 1395-4, 1395-5, 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 spray

19、 be used and printed by approved subscription and freemailing clients of the SABS.EN 1395-1:2007 (E) 4 1 Scope This European Standard specifies requirements for the acceptance inspection of thermal spraying equipment including plasma (atmospheric and with controlled atmosphere in chambers), arc and

20、flame including HVOF (high velocity oxygen-fuel) spray systems, as well as manipulator and powder feed systems used in spray jobs to produce thermally sprayed coatings of reproducible quality. This European Standard is applied to thermal spray equipment where components are supplied by one manufactu

21、rer/supplier. If one or more interdependent components of the thermal spray equipment are not from the same manufacturer/supplier the technical specification will be agreed between the manufacturer/supplier and user/customer. This European Standard is intended to form the basis of technical delivery

26、al spray equipment using gas mass flow controller, PLC and/or PC, monitor and/or a screen for process control shall be considered as an Class-A-System concerning accuracy as well as stability and reproducibility. A Class-A-System represents state of the art technology. This standard may only be used

27、 and printed by approved subscription and freemailing clients of the SABS.EN 1395-1:2007 (E) 5 4.1.2 Class B A more simple system using analogue gauges and/or flow meter for process control shall be considered at the least, as a Class-B-System concerning accuracy as well as stability and reproducibi

28、lity. 4.2 Health and safety Acceptance inspection as part of health and safety provisions for thermal spraying equipment serves to provide proof that the equipment is safe according to EC directives. This inspection will also cover the completeness of documentation with regard to CE conformity decla

29、ration. 4.3 Functionality The functionality of the thermal spraying equipment shall be checked according to the: 1) purchasing contract between contracting parties or if not mentioned; 2) suppliers order confirmation or if not mentioned; 3) technical data sheet. Using a suitable check list is recomm

30、ended. 4.4 Accuracy The accuracy of the thermal spraying equipment shall be checked according to the: 1) purchasing contract or if not mentioned; 2) suppliers manufacturers order confirmation or if not mentioned; 3) technical data sheet. Using a suitable inspection report is recommended. 4.5 Stabili

31、ty and reproducibility The acceptance inspection as part of a quality assurance system for spraying equipment serves to provide proof that the equipment is suitable for producing thermally sprayed coatings of uniform quality in particular, to satisfy the requirements of this European Standard. Proof

32、 of the suitability of equipment for thermal spraying is to be provided by the supplier when delivering a spray unit for the first time, but may also be verified by the user as described in Clause 6. The values thereby obtained and any other data of significance in deciding on the suitability of the

33、 equipment shall be recorded on report sheets or in an inspection report as shown in the documents listed in Clause 2. The spraying equipment shall be considered properly supplied if all the requirements specified in the tests and described in the corresponding parts of this European Standard are sa

34、tisfied. 5 Conditions for acceptance inspection All equipment shall be supplied with an operating and maintenance instruction manual. Spraying equipment shall be installed so that the spraying process is not impaired by other production equipment or environmental conditions. This standard may only b

Care shall be taken to ensure that no interference by fluctuations of the main power supply can influence the set points. The equipment

36、 shall be tested with the gun or burner in a fixed position and in a manner agreed between purchaser/supplier and manufacturer. The user/customer shall ensure a suitable supply of gas, electrical power and water as specified by the manufacturer/supplier. 6 Acceptance test according to technical spec

37、ification The following parts of this European Standard reveal the state of the art technology in thermal spraying equipment and the minimum requirements concerning a stable parameter setting and maintenance according to the respective class: Part 2: Flame spraying including HVOF; Part 3: Arc sprayi

38、ng; Part 4: Plasma spraying; Part 5: Plasma spraying in chambers; Part 6: Manipulator systems; Part 7: Powder feed systems. 7 Acceptance test according to coating specification 7.1 General Instead of the acceptance test according to the technical specification, an acceptance test according to coatin

39、g specification can be used. The coating specification shall be clarified before signing the contract and shall be part of the contract. 7.2 Coating properties All sprayed coating properties shall be specified by relevant or required values and/or a micro cross section, e.g.: type of thermal sprayin

40、g material; coating thickness; roughness (Ra/Rz); bond strength; porosity (%); interface bonding (%); oxides (%); This standard may only be used and printed by approved subscription and freemailing clients of the SABS.EN 1395-1:2007 (E) 7 non melted particles (%). Furthermore, the deposition efficie

41、ncy according to EN ISO 17836 can be specified. The thermal spraying material used for the acceptance tests shall be specified (e.g. according to EN 1274) and agreed. 7.3 Substrate properties The test piece or component shall be specified and agreed concerning: dimensions; pieces per time (for mass

42、or series production); area to be sprayed; substrate material; pretreatment. 7.4 Tolerances All tolerances for specified values shall be agreed among contracting parties. 8 Monitoring It shall be possible to monitor, clearly read and correct, by means of instruments, any deviations from the set poin

43、ts of the parameters of the spraying process. The error limits of the inspection instruments shall not exceed 5 % for all set points and shall correspond at least to class 2,5 1) . The reproducibility of the setting shall be verified. All values shall be recorded during acceptance inspection. 9 Insp

44、ection report An example for an inspection report for each type of thermal spraying equipment is given as an annex in each part of EN 1395 according to Clause 6. 10 Validity of inspection report and retest 10.1 Validity of inspection report The inspection report shall be deemed valid if all requirem

45、ents of this European Standard have been complied with. It is invalidated by deviations from this European Standard see 10.2. 10.2 Retest If the values obtained during acceptance inspection of a thermal spraying system are altered by modification or repair work, retesting of the properties affected

46、shall be carried out. Retesting shall be carried out in the same way as the initial tests are described in this European Standard. 1)Maximum permissible error expressed by percentage of a measuring span.
