Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected
6、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 towards their resolution. The use of American National Standards is completely voluntary; their
7、existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, 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
8、 circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority 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

The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdr

14、 reproduction or networking permitted without license from IHS -,-,- ii Foreword(This foreword is not part of American National Standard ANSI Z8.1-2006.) In 1922, the American Engineering Standards Committee (now American National Standards Institute) invited the Laundry Owners National Association,
15、 the Associa- tion of Government Labor Officials, and the National Association of Mutual Casualty Companies to act as sponsors for a safety code for laundry machinery and opera- tions. These associations accepted the sponsorship and, according to the procedure of AESC, organized a sectional committe
16、e to draft such a code. The code was ap- proved as a tentative standard in 1924. In 1941, it was advanced without revision to the status of American Standard. In 1953, the American Institute of Laundering (formerly Laundry Owners National As- sociation) resigned from the sponsorship, and the Institu
17、te of Industrial Launderers, Inc., was officially accepted as a sponsor for this project. The three sponsors, Inter- national Association of Governmental Labor Officials (formally AGLO), NAMCC, and IIL, submitted a revised scope, which was approved in June 1953. Several drafts of proposed revisions
18、were circulated and studied. After review and endorsement by Sectional Committee Z8, this revision was approved by the American Standards As- sociation (formerly American Engineering Standards Committee) in 1961. In 1970, IIL and Laundry and Cleaners Allied Trades Association (LACATA) spon- sored a
19、revival of the Z8 Committee for the purpose of updating American National Standard Z8.1-1961. The newly formed Z8 Committee met several times thereafter to review proposals on revisions of the standard received from the laundry and dry- cleaning industry and from other interested organizations. The
20、final draft of the stan- dard was approved in 1972. The standard was again revised in 1990. The Textile Care Allied Trades Association (TCATA), formerly LACATA, took over as Sponsor of the Z8 Committee and the standard was revised in 1996. The Z8 Committee met again in 2004, 2005 and 2006 to review
21、new proposals on the standard. The final draft of that standard was approved in late 2006. ANSI Z8.1-1996 had been approved on March 8, 1996. It was not revised or reaf- firmed within the next 10 years. Because of this inaction, and in accordance with ANSI procedures, ANSI administratively withdrew
22、the standard on March 8, 2006. ANSI Z8.1-2006 was therefore submitted for public review as a new standard. Suggestions for improvement of this standard are welcome. They should be sent to the Textile Care Allied Trades Association, Inc., 271 Route 46 West, #D203, Fairfield, NJ 07004. Consensus for t
23、his standard was achieved by use of the Canvass Method. The following organizations, recognized as having an interest in the standardization of safety requirements for Commercial Laundry and Drycleaning Operations were contacted prior to the approval of this revision of the standard. Inclusion in th
24、is list does not necessarily imply that the organization concurred with the submittal of the proposed standard to ANSI.

This definition is specifically NOT extended to include any subsets of machines in such a system. 3.31 Automatic Conventional Wash System: This term applies ONLY to convention

The adjective “automatic” is used in conjunction with multiple machines to define the fact that the controls include the ability to move goods between and in conjunction with other machine

Such systems typically require some irregular operator intervention. 3.32 Semi-automatic Conventional Wash System: This term applies ONLY to conventional
