European Foreword
This document (prEN 16474:2023) has been prepared by Technical Committee CEN/TC 145 “Plastics
and rubber machines”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16474:2015.
In comparison with the previous edition, the following technical modifications have been made:
— modification of the scope including machines for cycle and motorcycle tyres and Post Curing Inflator
(PCI);
— consideration of revised type-A and type-B standards;
— added safety requirements for Post Curing Inflator;
— added requirements related to rescue movement for the movable upper part and the loading device;
— introduced fire hazard and related safety requirements;
— considered the possibility to leave pressurized the bladder above the semi-closed position for a
limited time and also when safeguards are activated and to increase the pressure above the threshold
for a very short time;
— considered the possibility to install a shield in order to leave pressurized the bladder below the semi-
closed position for a limited time when safeguards are activated.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
Introduction
This European Standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type A or B
standards, the provisions of this type C standard take precedence over the provisions of the other
standards for machines that have been designed and built in accordance with the provisions of this type
C standard.
