The stand
27、ard was revised because:(1) Some paragraphs required modification for clarity and intent.(2) Additional details on electrical requirements were added.(3) Additional explanatory material and illustrations were added.(4) Additional definitions were required.(5) Some paragraphs required modification an
28、d some paragraphs were added to conform more closely to changes in technology.The project on safety requirements for the manufacture, care, and use of horizontalinjection molding machines was initiated under the auspices of the Injection MoldingSection of the Machinery Division, and the Safety Commi
29、ttee of the Molders Divisionof 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 o
30、f establishing necessarystandards.A standard treating the manufacture, care, and use of horizontal injection moldingmachines is complicated by the wide variety and sizes of machines manufacturedand in use, the virtually infinite combinations of parts being produced, the productionmethods used, and t
31、he operating conditions existing 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 approa
32、ch the problem of ma-chine safety as follows:The committee developed a list of hazards typical of HIMMs and listed these inclause 6 of this standard. For each hazard identified within the scope of the stan-dard, the committee assessed the potential severity of injury related to the hazard,the freque
33、ncy of exposure to the hazard, and possible avoidance. This process in-volved discussion among the committee, and resulted in the recommended preven-tive control measure included in clauses 7 through 11 inclusive and additional Annexreference material. Compliance with this standard is considered to
34、adequately con-trol hazards identified in clause 6. Other hazards not listed in clause 6 that can occurwith HIMMs may require additional preventive controls not included in this standard.To assist in the interpretation of these requirements, responsibilities have been as-signed to the manufacturer,
35、the remanufacturer, the modifier, and the employer.Since no new requirements have been added to this standard for existing machines,clauses 9 and 11 are effective on the approval date of this standard.Recognizing the impossibility of immediate updating of design and manufacturingmethods, clauses 7,
36、8, and 11 shall become effective one year after the approvaldate of this standard.Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-vSuggestions for improvement of this standard w
