4、Standards Review confirms that the requirements for due process, consensus, balance and openness have been met by the Society of the Plastics, Industry, Inc. (SPI, the ANSI-accredited standards developing organization). American National Standards are developed through a consensus process. Consensus
5、 is established when substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made
6、toward resolution. This process brings together volunteers and/or seeks out the views of persons who have an interest in the topic covered by this publication. While SPI administers the process and establishes procedures to promote fairness in the development of consensus, it does not write the docu
7、ment and it does not independently test, evaluate or verify the accuracy or completeness of any information or the soundness of any judgments contained in its standards or guidelines. American National Standards are promulgated through ANSI for voluntary use; their existence does not in any respect
8、preclude anyone, whether they have approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. However, users, distributors, regulatory bodies, certification agencies and others concerned may apply American Na
9、tional Standards as mandatory requirements in commerce and industry. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of an American National Standard. Moreover, no person shall have the right or authority to issue an interpreta
10、tion of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the Secretariat (SPI). Neither SPI nor any of the organizations or individuals that assisted in authoring, developing, editing and/or distributing this

Page | iv Foreword (This Foreword is not a normative part of American National Standard ANSI/SPI B151.20) This standard is a revision of American National Standard ANSI/SPI B151.20-1999: Requirements for the Manufacture, Care, and Use of Pl
25、astic Sheet Production Machinery. The standard was revised because: some paragraphs required modification for clarity and intent; additional explanatory material and illustrations were added; additional definitions were required; some paragraphs required modification and some paragraphs were added t
26、o conform more closely to changes in technology. SPI has long been concerned with operator safety on plastics processing equipment. Accordingly, the organization has established a standards development committee charged with the task of establishing necessary standards. The project on requirements f
27、or the manufacture, care, and use of plastic sheet production machinery was initiated under the auspices of the Extrusion Safety Committee of the Equipment Council of the Society of the Plastics Industry, Inc. (SPI). A standard treating the manufacture, care, and use of plastic sheet production mach
28、inery is complicated by the wide variety and sizes of machines manufactured and in use, and by the virtually infinite combinations of parts being produced, the production methods used, and the operating conditions existing in industry today. The primary objective of this standard is to minimize haza
29、rds to personnel associated with machine activity by establishing requirements for the manufacture, care, and use of these machines. To accomplish this objective, the committee decided to approach the problem of machine safety as follows: The committee developed a list of hazards common to Plastic S
30、heet Production Machinery and listed these in clause 6 of this standard. For each hazard identified within the scope of the standard, the committee assessed the potential severity of injury related to the hazard, the frequency of exposure to the hazard, and possible avoidance. This process involved
31、discussion among the committee, and resulted in the recommended risk reduction measures included in clauses 7 through 10 inclusive and additional Annex reference material. Compliance with this standard is considered to adequately control hazards identified in clause 6. Other hazards not listed in cl
32、ause 6 that can occur with Plastic Sheet Production Machinery may require additional risk reduction measures not included in this standard. To assist in the interpretation and implementation of these requirements, responsibilities have been assigned to the supplier, the remanufacturer, the modifier,
33、 and the user. Effective Date The following information on effective dates is informative guidance only, and not a normative part of this standard. This committee recognizes that some period of time after the approval date on the title page of this document is necessary for suppliers and users to de
34、velop new designs, or modify existing designs or manufacturing processes in order to incorporate the new or revised requirements of this standard into their product development or production system. This committee recommends that suppliers complete and implement design changes for new machines and m
35、achinery systems within 12 months of the approval of this standard. The committee recommends that users evaluate whether existing machinery and machinery systems have acceptable risk within 12 months of the approval date of this standard using generally recognized risk assessment methods. If the ris
36、k assessment shows that modification(s) is necessary, refer to the requirements of this standard or the machine-specific (C-level) standard to implement risk reduction measures (protective measures) for appropriate risk reduction.
