(Main + Amendment)Plastics and rubber machines - Reaction moulding machines - Part 1: Safety requirements for metering and mixing units
Plastics and rubber machines - Reaction moulding machines - Part 1: Safety requirements for metering and mixing units
This standard specifies the health and safety requirements for the design of metering and mixing units for reaction moulding machines. The significant and specific hazards are listed in clause 4 and are dealt with in this standard.
This standard does not cover completely the hazards arising from the use of highly flammable additives, for example, pentane used as a blowing agent (see 4.7), because these hazards depend to a large extent on the additives and processes used.
This standard does not cover the hazards arising from the assembly of separate units not supplied at the same time by the same manufacturer.
This standard does not cover the hazards arising from the movement of powered mixing heads; for these, see "EN 1612-2".
This standard applies to metering and mixing units manufactured after the date of publication of this standard.

Cette norme spécifie les exigences d'hygiène et de sécurité relatives à la conception des unités de dosage et de
mélange des machines de moulage par réaction. Les phénomènes dangereux significatifs et spécifiques sont
énumérés à l'article 4 et sont traités dans cette norme.
Cette norme ne couvre pas complètement les phénomènes dangereux provenant de l'utilisation d'additifs facilement
inflammables, par exemple le pentane utilisé comme agent d'expansion (voir 4.7), car ces phénomènes dépendent
principalement des additifs et du procédé utilisés.
Cette norme ne couvre pas les phénomènes dangereux résultant de l'assemblage de parties constitutives distinctes
n'ayant pas été livrées simultanément par le même fabricant.
Cette norme ne couvre pas les phénomènes dangereux associés aux mouvements des têtes de mélange
motorisées ; pour ces têtes de mélange, voir l’!EN 1612-2".
Cette norme s'applique aux unités de dosage et de mélange fabriquées après la date de publication de cette norme.
