Introduction

According to the classification of GB/T 15706, this document belongs to Class C standard. This document is particularly relevant to the following stakeholders involved in machinery safety. ---Machine manufacturer; ---Health and safety agencies. Other stakeholders affected by the level of machinery safety are. ---Machine users; ---Machine owner; ---Service providers; --- Consumer (when the machine is intended for use by a consumer). All of the above stakeholders may participate in the drafting of this document. The machines involved and the range of hazards, hazardous situations and hazardous events covered are given in the scope of this document. When the requirements of this document differ from those in Category A or Category B standards, For devices, the requirements of this document take precedence over those in other standards. Safety requirements for plastic blow molding machines

1 Scope

This document specifies the plastic hollow molding machine (including plastic extrusion blow molding machine, plastic extrusion blow molding machine, plastic injection molding machine Safety requirements for the design and manufacture of blow molding machines, plastic injection stretch blow molding machines, and blow molding machines that directly blow mold the parison and conformity verification, giving information on safe use of the machine. This document is applicable to the processing of plastic blow molding machines throughout their life cycle (see 5.4 in GB/T 15706-2012). All the consequences of the use of the plastic blow molding machine that may arise during the use of the machine and in the event of misuse that is reasonably foreseeable by the manufacturer. Major hazards, hazardous conditions and hazardous incidents (see Appendix A). NOTE. This document does not cover the design requirements for auxiliary equipment and the exhaust ventilation system itself, nor the hazards arising from the use of fluorine or other toxic substances.
