secretariat 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of an identical text or by endorsement, at the latest by july 2007, and conflicting national standards shall be withdrawn at the latest by july 2007.this document together with en 1395-1, 1395-2, 1395-3, 1395-5, 1395-6 and 1395-7 supersedes en1395:1996.en 1395 consists of the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; part 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 republic, denmark, estonia, finland, france, germany, greece, hungary, iceland, ireland, italy, latvia, lithuania, luxembourg, malta, netherlands, norway, poland, portugal, romania, slovakia, slovenia, spain, sweden, switzerland and united kingdom.1scopethis european standard specifies requirements for the acceptance inspection of thermal spraying equipment, in this case plasma spraying, 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.2normative referencesthe following referenced documents are indispensable for the application 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, classificationen 1274:2004, thermal spraying powders composition, technical supply conditionsen 1395-7, thermal spraying acceptance inspection of thermal spraying equipment part 7: powder feed systems3terms and definitionsfor the purposes of this document, the terms and definitions given in en 657:2005 and the following apply.3.1high voltage ignition deviceunit that generates a high voltage (kv) and low current (ma) between the electrodes of the plasma spraying torch in order to ignite the arc4principles of acceptance inspection4.1generalthe following clauses reveal state of the art technology in thermal spray equipment and the minimum requirements concerning a stable parameter setting and maintenance according to the classes given in annex a.4.2high-voltage ignition deviceother components and functions of the spraying equipment and other machines and/or equipment operated near by to the spraying equipment shall not be affected by operation of the high-voltage ignition device.4.3plasma gasesthe plasma spraying equipment shall be designed and installed in such a manner, that safe operation with plasma gases specified by the user will be achieved.4.4plasma spray nozzleprocessing of the spraying powder shall be possible without producing any disturbing deposits on and/or in the nozzle. nozzles with different shapes and powder ports (internal or external) may be used for special applications.4.5spraying powder feed unitthe powder feed unit shall be suitable for operation with the spraying equipment to be taken.the unit shall permit uniform processing of the powder required. it shall be possible to adjust the powder feed rate. the set points shall be constant and reproducible, which is a precondition for this being adequate and constant carrier gas pressure and flow.5procedure of acceptance inspection5.1generalspraying 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:5.2electrical powerproof of the power rating required shall be given by 20 min of spraying with the parameters for aluminium oxide according to en 1274:2004, 12.1 as recommended by the equipment manufacturer.during the test, the following items will be examined: electrical control; gas control; cooling water temperature.limits of deviation: see annex a; class a and class b.after stabilisation of arc and plasma, the deviation of the voltage (variable parameter) from the set point shall not exceed 3 % (class a) and 12 % (class b).5.3high-voltage ignition devicethe high-voltage ignition device shall be deemed to meet the requirements given in 4.2 if it does not interfere with any appliances and functions of the spraying equipment during the test as specified in 5.2. there should be no excessive erosion wear visible on the nozzle (spark).5.4plasma gasesthe system shall be deemed to comply with the specified requirements if the following requirements are satisfied by the acceptance inspection. the values of gas pressure and gas flow shall not deviate by more than 1,5 % (class a) and 5 % (class b) from the set points over a 20 min period of spraying. if the secondary gas is the variable parameter, the deviations from the set point shall not exceed 3 % (class a) and12 % (class b) after stabilisation. setting the primary gas pressure and/or flow rate shall not affect the corresponding values of the secondary gas and carrier gas and vice versa.5.5plasma spray nozzlethe nozzle shall be deemed to comply with the requirements specified in 4.4 if there are no disturbing deposits of spraying material on or in the nozzle when testing as specified in powder feed unitthe suitability of the system to process powders as specified in 4.5 shall be tested according to en 1395-7.6designationacceptance inspection of the thermal
