ISO/TC 270 - Plastics and rubber machines

This document specifies the essential safety requirements for the design, the construction and the integration of magnetic clamping systems (MCS) for plastics and rubber machines (e.g. injection moulding machines, compression moulding machines) and provides operational limits and information for their safe use. This document deals with the basic hazards, hazardous situations or hazardous events that are listed in Annex A, when an MCS is used utilizing magnetic force to affix a mould to the platen of a machine in which it is integrated, and provides requirements to eliminate or adequately reduce the risks associated with these hazards taking into consideration conditions of misuse that are reasonably foreseeable by the manufacturer. This document also specifies requirements for the MCS when integrated into a machine. This document does not deal specifically with hazards associated with production processes or other processes (e.g. horizontal or vertical injection moulding processes). Other standards can be applicable to these process hazards. This document does not cover hydraulic, pneumatic or mechanical clamping systems. This document is not applicable to MCS manufactured before the date of its publication.

This document specifies the essential safety requirements for the design and construction of injection moulding machines for the processing of plastics and/or rubber and provides information for their safe use. This document is applicable only to injection moulding machines with hydraulic and/or electrical drives for platen movement. This document deals with all significant hazards, hazardous situations and events relevant to injection moulding machines, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A) during the life cycle of the machinery (see ISO 12100:2010, 5.4). The following are not covered: — machines on which the clamping unit can only be operated by the physical force of the operator; — machines for which the hydraulic jack can only be manually operated; — injection blow moulding machines; — machines for reaction injection moulding; — compression moulding machines and transfer moulding machines; — direct-on sole moulding machines, unit sole and footwear component moulding machines, full shoe and boot moulding machines; — design of an exhaust system; — design and construction of the mould. NOTE Moulds and exhaust systems are not part of the machinery. This document is not applicable to injection moulding machines which are manufactured before the date of its publication.
