American National Standard Approval of an American Nat

4、ional Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by dir

5、ectly 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 toward their resolution. The use of American National Standards is

(See Section 7, Operational Requirements

25、.) NOTE: Consideration shall be given to reasonably foreseeable misuse of the baler for its intended application. It is not expected that every possible misuse will be foreseen, but the installer should use its best judgment and experience to reduce the risk of fire, electrical shock or injury to pe
