2、tariat American Society of Baking Approved 2006 American National Standards Institute, Inc. 2 American National Standard Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the stan
3、dards developer. Consensus is established when, in the judgement of the ANSI Board of Standards Review, 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 require
4、s that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, for manufacturing, marke
5、ting, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or autho
6、rity to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Stan
7、dard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling or

American National Standards Institute 25 West 43rdStreet New York, NY 10036 3 Forward (This forward is not part of American National Standard Z50.1-2006.) The American National Standards Institute and Secretariat (American Society of Baking) shall
9、not be responsible to anyone for the use of this standard, and will not incur any liability for damages resulting from the application or interpretation of this standard. This standard is a revision of American National Standard for Bakery Equipment - Safety Requirements, ANSI Z50.1-2000. Both the o
10、riginal standard and present revision were developed under the committee procedures of the American National Standards Institute to address the safety issues of machine design and operation. Current sanitation requirements published in ANSI/BISSC Z50.2-2003 are promulgated independently from this st
11、andard and should apply. This project had its inception in 1943. At the request of the American Society of Bakery Engineers, a general conference was held in New York City. As a result of that conference, the American National Standards Institute established the Z50 committee, with the American Soci
12、ety of Baking as secretariat. The committee was composed of manufacturers, users, insurance companies, unions, and governmental agencies. The standard was approved on August 4, 1947. The original was replaced by a revised standard, ANSI Z50.1-1971, modified by an addendum Z50.1a-1973, which was subs
13、equently revised as ANSI Z50.1-1977, ANSI Z50.1-1983, ANSI Z50.1-1988, ANSI Z50.1-1994, and ANSI Z50.1-2000. This revision, sponsored by the American Society of Baking, brings the standard up to date with the latest developments in the baking industry. All new installations of bakery machinery and e
14、quipment, individual items of new equipment, and new design, are to conform to the requirements of this standard. Suggestions for improvement in this standard will be welcome. They should be sent to the American Society of Baking, 27 East Napa Street, Sonoma, CA 95746, or through the ASB website at
15、www.asbe.org. This standard was processed and approved for submittal to ANSI by Accredited Standards Committee on Safety Requirements for Bakery Equipment, Z50. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. At the time it approved th
16、is standard, the Z50 Committee had the following members: Charles D.
