37、eed for a standard for gas lights which were being installed in large numbers in various sections of the country. The group accordingly authorized establishment of a subcommittee to have jurisdiction over standards for gas-fired illuminating appliances.The subcommittee on Approval Requirements for G

38、as-Fired Illuminating Appliances held its first meeting on April 5-6, 1960, at which time a tentative draft standard was adopted and the American Gas Association, Inc., Laboratories were requested to conduct experimental tests on representative types of gas lights. The results of these experimental

39、tests were reviewed by the subcommittee at its April 17, 1962 meeting, at which time a draft standard was adopted for review and comment.The draft standard was distributed for review and comment during June, 1962. It was reconsidered by the subcommittee at its September 13, 1962 meeting, in the ligh

40、t of comments received. The resultant standard was ratified by the ASA Sectional Committee Z21 by letter ballot.The first edition was later approved by the sponsor, the American Gas Association, Inc., and endorsed as an American Standard by the American Standards Association, Inc., on July 26, 1963.

41、On August 24, 1966, the American Standards Association, Inc., was reconstituted as the United States of America Standards Institute. On October 6, 1969, the United States of America Standards Institute was renamed American National Standards Institute, Inc.Following the same procedure outlined above

42、, further revisions deemed necessary in line with developments in the industry were endorsed by the American National Standards Committee Z21 at its February 18, 1970 meeting. The third edition was subsequently endorsed as American National Standard by the American National Standards Institute, Inc.

43、, on April 8, 1993.This, the fourth edition, was approved by the Technical Committee on Standards for Performance and Installation of Gas Burning Appliances and Related Accessories on October 2, 2013; and subsequently by the American National Standards Institute on October 18, 2013.Previous editions

44、 of gas-fired illuminating appliance standard, and addenda thereto, approved by the American National Standards Institute or its predecessor organizations are as follows:Z21.42-1963 Z21.42a-1970Z21.42-1971 Z21.42a-1973Z21.42b-1981Z21.42-1993 Z21.42a-2004Note: This 2013 edition of ANSI Z21.42 incorpo

46、and materials:a) for use with natural gas;b) for use with manufactured gas;c) for use with mixed gas;d) for use with liquefied petroleum gases;e) for use with butane gas; andf) for use with LP gas-air mixtures.The construction of illuminating appliances for use with the above-mentioned gases is cove

47、red under Clause 4, Construction.The performance of illuminating appliances for use with the above-mentioned gases is covered under Clause 5, Performance.1.2 This standard also covers gas-fired illuminating appliances for either outdoor or indoor installation, or both, for attachment to fixed gas pi

48、ping systems.1.3 Appliances found suitable for indoor use under this standard are satisfactory for use in mobile homes or travel trailers when properly installed.1.4 This standard is not intended to cover open-flame illuminating appliances having an input rating in excess of 5,000 Btu per hour (1 46

49、5 W) per burner.1.5 All references to psi throughout this standard are to be considered gage pressures unless otherwise specified.1.6 Clause 2, Reference publications, contains a list of standards specifically referenced in this standard and sources from which they may be obtained.ANSI Z21.42-2013Gas-fired illuminating appliancesNovember 2013 2013 CSA Group 122 Reference publicationsCSA GroupANSI Z21.15-1997 (R2008)/CGA 9.1-M97, and Addenda ANSI Z21.15a-2001(R2008)/CGA 9.1a-2001 (R2008), and Addenda ANSI Z21.15b-2001 (R2008)/CGA 9.1b-2001 (R2008),Manually Oper
