13、2003.)This standard is a revision of American National Standard for Plastics Machinery - In-jection Blow Molding Machines - Safety Requirements for the Manufacture, Care,and Use, ANSI/SPI B151.21-2000. The standard was revised because some para-graphs (5.2.4 and 5.2.5) required modification to confo
14、rm more closely to changes intechnology.The project on safety requirements for the manufacture, care, and use of injectionblow molding machines was initiated under the auspices of the Injection Blow Mold-ing Section of the Machinery Division, and the Safety Committee of the Molders Man-agement Divis
15、ion, of the Society of the Plastics Industry, Inc. (SPI).Both divisions of the SPI have long been concerned with operator safety on plasticsprocessing equipment. Accordingly, each section of the divisions has established astandards development committee charged with the task of establishing necessar
16、ystandards.A standard treating the manufacture, care, and use of injection molding machines iscomplicated by the wide variety and sizes of machines manufactured and in use, andby the virtually infinite combinations of parts being produced, the production methodsused, and the operating conditions exi
17、sting in industry today.The primary objective of this standard is to minimize hazards to personnel associatedwith machine activity by establishing requirements for the manufacture, care, anduse of these machines.To accomplish this objective, the committee decided to approach the problem of ma-chine
18、safety from two directions:1) Eliminating by design certain recognized hazards and establishing standardapproaches to design so that machines available from competitive manufacturerswill have similar operational characteristics2) Safeguarding the machine to protect personnel from recognized hazardsT

20、val date of this standard, a3-year period has been provided to employers for updating machines.Recognizing the impossibility of immediate updating of design and manufacturingmethods, clauses 5 and 8 shall become effective one year after the approval date ofthis standard.Suggestions for improvement o
21、f this standard will be welcome. They should be sentto the Society of the Plastics Industry, Inc, 1801 K Street, NW, Suite 600K, Washing-ton, DC 20006-1301.Consensus for this standard was achieved by use of the Canvass Method.iiiThe following organizations recognized as having an interest in the sta

30、uirements for the manufacture of ancillary equipment for IBMMs are not cov-ered by this standard. 1.2 Purpose The purpose of this standard is to minimize hazards to personnel. 1.3 Application Injection Blow Molding Machines shall be referred to as IBMMs throughout this stan-dard. 1.3.1 New Installat
31、ions The requirements of this standard pertaining to manufacture shall apply to all new or re-manufactured IBMMs installed in the United States of America. Date of manufacture of the new or remanufactured machine (month and year) shall be affixed permanently and legibly to the machine along with the
32、 name of the manufacturer or remanufacturer. Compliance shall be achieved within one year after the approval date of this standard.
