EN 12921-1-2005使用液体或蒸气的工业产品的表面清洁和预处理机器.第1部分:通用安全要求.包含修改件A1-2010

This standard applies to machines for surface cleaning and pre-treatment-in the following called \"cleaning machines\"-of industrial items using liquids or vapours, i.e. stationary machines and related equipment for automated and manual cleaning and pre-treatment processes. NOTE Cleaning machines are operated with or without heating, for example as dipping or spraying or vapour condensation process, where additional using of ultrasound is possible. These cleaning machines could be designed as single-zone or multi-zone machine, chamber machines, drum cleaning machine, low lift truck machines, round time machines or tunnel (continuous) machines. To the extent of this document, cleaning machines for industrial items are considered as an assembly of the following equipment: pump(s) and/or other mechanical system of agitation, recirculation and spraying of cleaning liquid; forced ventilation system; heating system with temperature control; condensation system; filtration and separation system and/or solid particles extraction from the liquid; conveyor and/or handling system for the items to be processed; product handling systems and reciprocators which are part of the cleaning machine; control and/or monitoring systems; liquid handling system.This European Standard deals with the common significant hazards, hazardous situations and events relevant to cleaning machines for industrial items using liquids or vapours when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4).This part of the standard defines the common safety requirements for all kinds of cleaning machines for industrial items using liquids or vapours and related common devices and should be used in connection with other parts of the EN 12921-series. The specific requirements specified in part 2 and following parts of EN 12921 take precedence over the respective requirements in EN 12921. NOTE In addition, where a cleaning machine is not covered by a specific part of this document, part 1 of EN 12921 can be used to establish the approach for dealing with the relevant risks. Specific hazards which are related to the type of cleaning liquid used are dealt with in the following documents: EN 12921-2 for water based cleaning liquids; EN 12921-3 for flammable cleaning liquids; prEN 12921-4 for halogenated solvents.This standard is not applicable to machines for: mobile portable cleaning; high pressure cleaning with high pressure water jet according to prEN 1829-1; conveyor dishwashing according to EN 50416; surface cleaning employing liquids according to EN 60335-2-54; commercial electric dishwashing according to EN 60335-2-58; cleaning with high pressure and steam according to EN 60335-2-79; plasma cleaning; mechanical blasting; thermal cleaning; drying processes; cleaning of textiles or clothes; food processing.This standard is not applicable to the following equipment; loading and unloading systems; automatic systems, e. g. robots as covered by EN ISO 10218-1; centrifuges as covered by EN 12547; pumps and pump units for liquids as covered by EN 809.This standard is not applicable to cleaning machines for industrial items which are manufactured before the date of publication of this document by CEN.

1.1 This standard applies to machines for surface cleaning and pre-treatment – in the following called\"cleaning machines\" – of industrial items using liquids or vapours, i.e. stationary machines and relatedequipment for automated and manual cleaning and pre-treatment processes.NOTE Cleaning machines are operated with or without heating, for example as dipping or spraying or vapourcondensation process, where additional using of ultrasound is possible. These cleaning machines could be designed assingle-zone or multi-zone machine, chamber machines, drum cleaning machine, low lift truck machines, round timemachines or tunnel (continuous) machines.To the extent of this document, cleaning machines for industrial items are considered as an assembly of thefollowing equipment: pump(s) and/or other mechanical system of agitation, recirculation and spraying of cleaning liquid; forced ventilation system; heating system with temperature control; condensation system; filtration and separation system and/or solid particles extraction from the liquid; conveyor and/or handling system for the items to be processed; product handling systems and reciprocators which are part of the cleaning machine; control and/or monitoring systems; liquid handling system.1.2 This European Standard deals with the common significant hazards, hazardous situations and eventsrelevant to cleaning machines for industrial items using liquids or vapours when they are used as intendedand under the conditions foreseen by the manufacturer (see clause 4). This part of the standard defines thecommon safety requirements for all kinds of cleaning machines for industrial items using liquids or vapoursand related common devices and should be used in connection with other parts of the EN 12921-series. Thespecific requirements specified in part 2 and following parts of EN 12921 take precedence over the respectiverequirements in EN 12921.NOTE In addition, where a cleaning machine is not covered by a specific part of this document, part 1 of EN 12921can be used to establish the approach for dealing with the relevant risks.Specific hazards which are related to the type of cleaning liquid used are dealt with in the followingdocuments: EN 12921-2 for water based cleaning liquids; EN 12921-3 for flammable cleaning liquids; prEN 12921-4 for halogenated solvents.1.3 ! This standard is not applicable to machines for:− mobile portable cleaning,− high pressure cleaning with high pressure water jet according to prEN 1829-1,− conveyor dishwashing according to EN 50416,− surface cleaning employing liquids according to EN 60335-2-54,− commercial electric dishwashing according to EN 60335-2-58,− cleaning with high pressure and steam according to EN 60335-2-79,− plasma cleaning,− mechanical blasting,− thermal cleaning,− drying processes,− cleaning of textiles or clothes,− food processing.This standard is not applicable to the following equipment:− loading and unloading systems,− automatic systems, e.g. robots as covered by EN ISO 10218-1,− centrifuges as covered by EN 12547,− pumps and pump units for liquids as covered by EN 809.\"1.4 This standard is not applicable to cleaning machines for industrial items which are manufactured beforethe date of publication of this document by CEN.
