This European Standard deals with all significant hazards, hazardous situations and hazardous events relevant to ovens and dryers in which flammable substances are released by evaporation from and curing of coating materials.The specific significant risks related to the use of this machinery with foodstuff and pharmaceutical products are not dealt with in this European Standard.This European Standard is only applicable to machines which are used as intended and under the conditions which are foreseeable as malfunction by the manufacturer (see Clause 4).For ovens and dryers in which flammable substances are released by evaporation from and curing of coating materials, in which the concentration of these flammable substances shall not, under no circumstances, exceed 3 % of the LEL, EN 746-1 and EN 746-2 may be applied instead of this European Standard.This European Standard is not applicable to:—ovens for hardening metals;—enamelling plants;—portable heating systems for drying (for instance infrared radiant heaters, hot-air blowers, blow-dryers);—solvent recovery plants;—distillation and/or refraction plants;—textile dry-cleaning systems.This European Standard is not applicable to machinery manufactured before the date of its publication as EN.
