3、roving this American National Standard, the ANSI Board of Standards Review confirms that the requirements for due process, consensus, balance and openness have been met by B11 Standards, Inc., (the ANSI-accredited standards developing organization). American National Standards are developed through

4、a consensus process. Consensus 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 th

5、at a concerted effort be made 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 B11 Standards, Inc., administers the process and establishes procedures to promote fairness in the devel

6、opment of consensus, it does not write the document 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 voluntar

7、y use; their existence does not in any respect 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 agen

8、cies and others concerned may apply American National 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 hav

9、e the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute.

29、his Subcommittee recognizes that some period of time after the approval date on the title page of this document is necessary for suppliers and users to develop new designs, or modify existing designs or manufacturing processes in order to incorporate the new or revised requirements of this standard

30、into their product development or production system. This Subcommittee recommends that suppliers complete and implement design changes for new machines within 30 months of the approval of this standard. For existing or modified machines, this Subcommittee recommends that users should confirm that th

31、e equipment / process has tolerable risk using generally recognized risk assessment methods within 30 months of the approval date of this standard. If the risk assessment shows that modification(s) is necessary, refer to the requirements of this standard to implement protective measures for appropri

32、ate risk reduction. This standard was processed and submitted for ANSI approval by the B11 Accredited Standards Committee on Safety Standards for Machines. Committee approval of this standard does not necessarily imply that all committee members voted for its approval. At the time this standard was
