ÖNORM EN 1539

This standard deals with all significant hazards relevant to dryers and ovens, in which flammable substances are released, when they are used as intended and under the conditions foreseen by the manufacturer (see clause 4). This standard is applicable to dryers, ovens and other evaporating equipment used in the pre-treatment, printing, coating and/or impregnating processes of surfaces and/or materials. This standard gives the requirements for the design of such equipment which in the course of drying and/or curing release flammable substances, predominantly volatile organic compounds (V.O.C s). This standard details all anticipated significant hazards associated with the equipment (listed in clause 4) and specifies the appropriate safety requirements (listed in clause 5) to be met by the manufacturer to ensure the safety of persons and property during commissioning, start-up, operation, shut-down and maintenance. This standard is not applicable to portable heaters used for drying, pharmaceutical and food drying processes, combined booths (see prEN 13355), solvent recovery systems. For dryers, ovens and other evaporating equipment which do not in any circumstances have a concentration of flammable substances (VOC) exceeding 3 % LEL compliance with EN 746-1 and EN 746-2 can be used as an alternative to this standard. This standard applies to dryers, ovens and other evaporating equipment in which flammable substances are released, which are manufactured after the date of issue of this standard.
