Anotation

IEC 63458-1:2026 contains safety-related requirements for high pressure water jet units with drives of all kinds (e.g. electric motor, internal combustion engine, air and hydraulic) in which pumps are used to generate pressure. This document deals with all significant hazards, hazardous situations and events arising during assembly, erection, operation and servicing relevant to high pressure water jet units, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. All references to high pressure water jet units within this document include machines for one or more of the following industrial applications: – cleaning; – surface preparation; – material removal; – readjustment of concrete; – cutting. This document applies to mobile and fixed high pressure water jet units, in which the water pressure is generated by a pressure generator/pump and in which the maximum allowable working pressure is more than the upper limit fixed in the scope of IEC 60335-2-79 (35 MPa is currently the upper limit for machines covered by IEC 60335-2-79). This document does not cover: – high pressure cleaners which are dealt with in IEC 60335-2-54; – additional hazards due to the incorporation of high pressure water jet units into other process-technology machines; – specific hazards associated with explosive atmospheres, use on ships or ambient temperatures outside the range 5 °C to 40 °C; – hazard due to the nature of liquids used for jetting, other than that due to pressure; – hazards associated with the drives or specific hazards due to any heat generation function. However, the hazards due to high temperatures of touchable surfaces are dealt with; – high pressure water jet units which are manufactured before the date of its publication as IEC standard; – high pressure water jet hoses which are covered by IEC 63458-2; – high pressure water jet spraying device which are covered by IEC 63458-3; Tests according to this document are type tests unless they relate to routine (informative) tests to be carried out during series manufacture. Compliance with IEC 63458-1, IEC 63458-2 and IEC 63458-3 provides the full requirements for high pressure water jet machines. LIEC 63458-1:2026 etablit les exigences relatives a la securite pour les unites a jet deau a haute pression equipees de mecanismes de commande de tous types (moteur electrique, moteur a combustion interne, moteur pneumatique et moteur hydraulique, par exemple) dans lesquelles la pression est generee par des pompes. Le present document traite de lensemble des phenomenes dangereux significatifs, situations dangereuses et evenements dangereux qui surviennent lors de lassemblage, du montage, du fonctionnement et de lentretien des unites a jet deau a haute pression, lorsque celles-ci sont utilisees dans les conditions prevues et dans les conditions de mauvais usage raisonnablement previsible etablies par le fabricant. Dans le present document, toutes les references aux unites a jet deau a haute pression concernent les machines destinees a une ou plusieurs des applications industrielles suivantes: – nettoyage; – preparation de surfaces; – enlevement de materiaux; – ragreage du beton; – decoupe. Le present document sapplique aux unites a jet deau a haute pression mobiles et fixes, dans lesquelles la pression deau est generee par une pompe/un generateur de pression et la pression de service maximale admissible est superieure a la limite superieure fixee dans le domaine dapplication de lIEC 60335-2-79 (La limite superieure pour les machines couvertes par lIEC 60335-2-79 est actuellement de 35 MPa). Le present document ne couvre pas: – les appareils de nettoyage a haute pression qui sont traites dans lIEC 60335-2-54; – les autres dangers lies a lincorporation dunites a jet deau a haute pression dans dautres machines de technologie de procede; – les dangers specifiques lies aux atmospheres explosives, a lutilisation a bord de navires ou a des temperatures ambiantes en dehors de la plage 5 °C a 40 °C; – les dangers dus a la nature des liquides utilises pour les jets, autres que les dangers dus a la pression; – les dangers lies aux mecanismes de commande ou les dangers specifiques dus aux fonctions de production de chaleur. Toutefois, les dangers dus aux temperatures elevees des surfaces pouvant etre touchees sont couverts; – les unites a jet deau a haute pression qui ont ete fabriquees avant la date de publication du present document en tant que norme de lIEC; – les flexibles a jet deau a haute pression couverts par lIEC 63458-2; – les dispositifs pulverisateurs a jet deau a haute pression couverts par lIEC 63458-3. Les essais conformes au present document sont des essais de type, sauf sils concernent des essais individuels de serie (informatifs) qui doivent etre effectues au cours de la fabrication en serie. La conformite a lIEC 63458-1, a lIEC 63458-2 et a lIEC 63458-3 fournit les exigences completes pour les machines a jet deau a haute pression.
