2、 Inc.Approved December 1, 2006American National Standards Institute, Inc.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the ju

3、dgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a con

10、 National Standard ANSI Z8.1-2006.)In 1922, the American Engineering Standards Committee (now American NationalStandards Institute) invited the Laundry Owners National Association, the Associa-tion of Government Labor Officials, and the National Association of Mutual CasualtyCompanies to act as spon

11、sors for a safety code for laundry machinery and opera-tions. These associations accepted the sponsorship and, according to the procedureof AESC, organized a sectional committee to draft such a code. The code was ap-proved as a tentative standard in 1924. In 1941, it was advanced without revision to

12、the status of American Standard.In 1953, the American Institute of Laundering (formerly Laundry Owners National As-sociation) resigned from the sponsorship, and the Institute of Industrial Launderers,Inc., was officially accepted as a sponsor for this project. The three sponsors, Inter-national Asso

13、ciation of Governmental Labor Officials (formally AGLO), NAMCC, andIIL, submitted a revised scope, which was approved in June 1953. Several drafts ofproposed revisions were circulated and studied. After review and endorsement bySectional Committee Z8, this revision was approved by the American Stand

14、ards As-sociation (formerly American Engineering Standards Committee) in 1961.In 1970, IIL and Laundry and Cleaners Allied Trades Association (LACATA) spon-sored a revival of the Z8 Committee for the purpose of updating American NationalStandard Z8.1-1961. The newly formed Z8 Committee met several t

15、imes thereafterto review proposals on revisions of the standard received from the laundry and dry-cleaning industry and from other interested organizations. The final draft of the stan-dard was approved in 1972. The standard was again revised in 1990.The Textile Care Allied Trades Association (TCATA

16、), formerly LACATA, took over asSponsor of the Z8 Committee and the standard was revised in 1996.The Z8 Committee met again in 2004, 2005 and 2006 to review new proposals on thestandard. The final draft of that standard was approved in late 2006.ANSI Z8.1-1996 had been approved on March 8, 1996. It

17、was not revised or reaf-firmed within the next 10 years. Because of this inaction, and in accordance withANSI procedures, ANSI administratively withdrew 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 standa

18、rd are welcome. They should be sent tothe Textile Care Allied Trades Association, Inc., 271 Route 46 West, #D203, Fairfield,NJ 07004. Consensus for this standard was achieved by use of the Canvass Method.The following organizations, recognized as having an interest in the standardizationof safety re

Inclusion in this listdoes not necessarily imply that the organization concurred with the submittal of theproposed standard to ANSI.David Cotter, Z8 Committee SecretaryA

22、to wrap or tie articles. 3.17 puff irons: A heated device for smoothing or shaping textile articles. 3.18 shall: This term denotes a requirement. 3.19 should: This term denotes a recommendation. 3.20 singular form: Where these standards refer to a person or a device in singular form, it shall be int

23、erpreted to apply also to persons and devices. 3.21 squeeze extractor: Any mechanically, pneumatically, or hydraulically operated compacting machine for removing excess liquid from textile articles by squeezing. 3.22 textile article: Woven, knitted, or other fabric. . 3.23 tumbler: A machine in whic

24、h textile articles are shaken out or dried by tumbling within a rotating cylinder. 3.24 washer/extractor: Any machine in which both the washing and extraction operations are performed. 3.25 washing machine: A machine used for washing, but not extracting water from, textile articles. 3.26 wringer: On

25、e or more power-driven rolls used for removing excess liquid from textile articles. 3.27 manual: This adjective, when used in conjunction with a machine, defines the fact that the machine was designed to operate with the physical intervention of an operator and would include semi-automatic and autom

26、atically timed laundry and drycleaning garment presses and cabinet garment presses. 3.28 Jog or jogging: Controlled low speed rotation of the cylinder or basket to assist the loading or unloading of the machine. This applies to open pocket washer extractors and tumblers. 3.29 Washroom System Conveyo

27、rs: Non-stationary conveyors incorporated into automatic, semi-automatic or tunnel washing systems which either traverse or elevate, or do both, without physical intervention of an operator. 3.30 Tunnel Washing System: A complete washing/drying system comprised of continuous tunnel washer(s), means

29、 the dryers. 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 conventional washing and drying systems from when goods enter the washer/extractor(s) until such goods exit the dryer(s).

30、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 machines in a system and/or to move machines themselves without direct operator involvement. This definition refers to

31、the intended design of the system. Such systems typically require some irregular operator intervention. 3.32 Semi-automatic Conventional Wash System: This term applies ONLY to conventional washing and drying systems from when goods enter the washer/extractor(s) until such goods exit the dryer(s). Th

32、e adjective “semi-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 machines in a system and/or to move machines themselves but requires some operator involvement in the process. This

33、specifically includes any integrated system of machines that requires an operator to control the ANSI Z8.1-2006 4 loading of a washer/extractor and/or unloading onto a shuttle conveyor which then may automatically convey goods to a dryer. 4 Equipment 4.1 General requirements 4.1.1 Power transmission

On such a machine: a) with a single access door, the interlock shall, however, enable the operator to inch or jog the cylinder with the access door open; b) with two or more access doors, the interlock shall enable the operator to inch or jog the cylinder only with the access door adjacent to the jog controls open while all other access doors must be closed. In either of these cases, the ANSI Z8.1-2006 6 jog control shall require the operator to press two buttons momentarily with both hands simulta
