Chapter 3 in this standard is for recommendation, the rest are for enforcement. The modification on this standard is bad on Safety Requirements for High Pressure Metal Die Casting Units EN869:1998 (English version). This standard is a new draft bad on Safety Requirements for High Pressure Metal Die Casting Units EN869:1998, which technically distinguishes itlf from EN869:1998 in the following aspects:
—Editing modification bad on the original standard;
— Deleted the preface and introduction part of the International Standard;
— Deleted the Sources of Standards which appear in the catalogue of Cited Normative Document while fail to appear in the text, and added the Cited Normative Document which appear in the original text while fail to appear in the catalogue;
— the tables in the chapter that describes the glossaries and definitions in the original standard in the form of claus, are changed;
— a title for 7.1 of the original standard added;
— Deleted Appendix A in the original standards which are not

Safety Requirements for high
pressure metal die casting unit
1 Scope
This standard specifies the safety requirement for high pressure metal
die casting unit. The standard applies to die-casting machine and its
accessory equipment, such as feed, core puller and spraying equipment.
The standard does not apply to low pressure die casting machine,
gravity casting machine as well as lost wax casting machine.
